How Blood Pressure Works Animation - Understanding Blood Pressure Measurement Monitor Readings Video
 
01:44
Normal blood pressure is important for proper blood flow to the body’s organs and tissues. The force of the blood on the walls of the arteries is called blood pressure. Blood pressure is measured both as the heart contracts, which is called systole, and as it relaxes, which is called diastole. Normal blood pressure is considered to be a systolic blood pressure of 115 millimeters of mercury a diastolic pressure of 70 millimeters of mercury (stated as "115 over 70"). If an individual were to have a consistent blood pressure reading of 140 over 90, he would be evaluated for having high blood pressure. If left untreated, high blood pressure can damage important organs, such as the brain and kidneys, as well as lead to a stroke. High blood pressure is a common disease in which blood flows through blood vessels (arteries) at higher than normal pressures. Measuring Blood Pressure Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure, sometimes called hypertension, happens when this force is too high. Health care workers check blood pressure readings the same way for children, teens, and adults. They use a gauge, stethoscope or electronic sensor, and a blood pressure cuff. With this equipment, they measure: Systolic Pressure: blood pressure when the heart beats while pumping blood Diastolic Pressure: blood pressure when the heart is at rest between beats Health care workers write blood pressure numbers with the systolic number above the diastolic number. For example: 118/76 mmHg People read "118 over 76" millimeters of mercury. Normal Blood Pressure: Normal blood pressure for adults is defined as a systolic pressure below 120 mmHg and a diastolic pressure below 80 mmHg. It is normal for blood pressures to change when you sleep, wake up, or are excited or nervous. When you are active, it is normal for your blood pressure to increase. However, once the activity stops, your blood pressure returns to your normal baseline range. Blood pressure normally rises with age and body size. Newborn babies often have very low blood pressure numbers that are considered normal for babies, while older teens have numbers similar to adults. Abnormal Blood Pressure Abnormal increases in blood pressure are defined as having blood pressures higher than 120/80 mmHg. The following table outlines and defines high blood pressure severity levels. The ranges in the table are blood pressure guides for adults who do not have any short-term serious illnesses. People with diabetes or chronic kidney disease should keep their blood pressure below 130/80 mmHg. Although blood pressure increases seen in prehypertension are less than those used to diagnose high blood pressure, prehypertension can progress to high blood pressure and should be taken seriously. Over time, consistently high blood pressure weakens and damages your blood vessels, which can lead to complications. Types of High Blood Pressure There are two main types of high blood pressure: primary and secondary high blood pressure. Primary High Blood Pressure Primary, or essential, high blood pressure is the most common type of high blood pressure. This type of high blood pressure tends to develop over years as a person ages. Secondary High Blood Pressure Secondary high blood pressure is caused by another medical condition or use of certain medicines. This type usually resolves after the cause is treated or removed. Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. When used without further specification, "blood pressure" usually refers to the arterial pressure in the systemic circulation. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature. Normal resting blood pressure in an adult is approximately 120/80 mm Hg. Blood pressure varies depending on situation, activity, and disease states. It is regulated by the nervous and endocrine systems. Blood pressure that is low due to a disease state is called hypotension, and pressure that is consistently high is hypertension. Both have many causes which can range from mild to severe. Both may be of sudden onset or of long duration. Long term hypertension is a risk factor for many diseases, including kidney failure, heart disease, and stroke. Long term hypertension is more common than long term hypotension in Western countries. Long term hypertension often goes undetected because of infrequent monitoring and the absence of symptoms. Physiology: During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. Q. What blood pressure should I have? What is normal blood pressure?

HIGH BLOOD PRESSURE | HYPERTENSION | HIGH BLOOD PRESSURE SYMPTOMS AND TREATMENT IN URDU/HINDI

HIGH BLOOD PRESSURE | HYPERTENSION | HIGH BLOOD PRESSURE SYMPTOMS AND TREATMENT IN URDU/HINDI HIGH BLOOD PRESSURE: High blood pressure is also known as hypertension, caused by the increase in blood circulation in the body. If it is not treated on time, it can cause brain haemorrhage, coma and even death. For this reason it is vital that it be taken proper care of. The most important thing to know about high blood pressure control what it exactly it, what causes and what are the ways to treat this health condition. Heart Pumping and Blood Pressure: Human body contains 5-6 liters of blood depending on the sex and age. Almost 5 liters of blood passes through the heart and is purified every second. Heart separates deoxygenated blood from oxygenated blood, send the deoxygenated blood to the lungs for getting oxygen and the oxygenated blood to all part of the body. This process is done by the contraction & relaxation of the heart muscles, each cycle called a heart beat. After purifying the blood, it delivers the blood to all body parts through veins and arteries. The amount of heart beats depends on the flow of blood from the heart. If the pressure of blood flow is high, the heart beat rate will also be higher. Same is the other way around. This increased or decreased blood pressure causes the veins & valves to contract and expand accordingly putting pressure on the blood vessels and the heart. Symptoms: Headache Vomit Low energy level Weak eye sight Improper working of digestive system How to measure the blood pressure & its diagnosis: The first step in high blood pressure treatment is diagnosing whether a patient has high BP of low. If the blood circulation is 140 / 90 torr or higher, then it will be categorized as high blood pressure. 139 / 89 torr pressure is known as pre-hyper tension, which indicates that it is the starting point of blood pressure. Diagnosis process needs to be carried according to following parameters: Sample should be examined three times in a week. If the blood pressure of the patient is very high then one should wait for half hour then check the blood pressure again. The blood pressure is measured with a strip and from upper part of arm. BP is measured in “mmhg”, which is known as Cardiac Output or heart rate; increased heart rate indicates high blood pressure. According to the American Heart Association blood pressure in measured in two parameters; Dialectic mmhg and Systolic mmhg. In a healthy human being, the level of systolic & dialectic blood mmhg should be according to the following figures. Systolic mmhg: hypertension 90, 90 – 119 Dialectic mmhg: hypertension 60, 60 – 79 High Blood Pressure Treatment: It important to avoid the things that cause high blood pressure in the first place. Hypertension is divided into five stages, first two stages are not very dangerous and by self precautions, you can prevent severe hypertension. At this stage patient should avoid foods with high fats, smoking & exercise regularly. Salt is the main cause of high blood pressure and drug therapy & Beta blockers are suggested for the patients. Eating a healthy diet and emphasizing on natural diet like fruits and vegetables can help control blood pressure a lot. If you have developed High BP, it is very important that you get checkup every now and then. Lastly, it depends on you that how much you are willing to control hypertension. Take things lightly, take exercise, take some time out for yourself away from routine life, go out with friends and add fun to your life. You won’t even know when you came out of it.

Blood Pressure
 
06:36
When you go the doctor to get your blood pressure measured, you will hear two numbers, for example; 120/80. What do those numbers mean? In order to understand the subject of blood pressure, we first have to know some information about the circulatory system (cardiovascular system). The circulatory system is made up of organs that work together: the heart; lungs; blood vessels; and blood. The heart, blood, and blood vessels make up the cardiovascular component of the circulatory system. The heart is a muscle the size of your fist. It constantly pumps blood through the blood vessels. The blood carries oxygen and nutrients to the body’s organs and drops off waste products to be filtered out by the kidneys, liver, lungs, and skin. Each heart beat pushes blood out of the heart into the arteries, then the heart relaxes while getting ready for the next pumping beat. So, in fact we observe two actions here: contraction and relaxation. The contraction is called systole, and the relaxation: diastole. The blood pressure is the amount of pressure exerted on your artery walls by the blood flowing into them, under the effect of the heart’s pumping action. Now let’s see, if the heart contracts to push the blood forward, this must be causing a higher pressure on the artery walls than when it relaxes, right? Exactly! So there are actually two readings for the blood pressure in one person: one while the heart contracts, which causes the higher pressure value: called systolic pressure; and the other when the heart relaxes/rests, called the diastolic pressure. The systolic pressure is the upper/higher one, and the diastolic is the lower one. Now let’s have a further look at the measurement unit of blood pressure. We say for example that my blood pressure is 120/80 mm of mercury. Which means that the blood presses on the walls of the arteries with the same pressure of a 1-mm thick column of mercury with the height of, say 120 mm, which is “the value we read”. A sphygmomanometer and a stethoscope are devices used to record your blood pressure. A sphygmomanometer consists of an inflatable cuff, a measuring unit (the mercury manometer, or aneroid gauge), and a mechanism for inflation which may be a manually operated bulb and valve or a pump operated electrically. The cuff is normally placed to fit around an upper arm, at roughly the same vertical height as the heart while the subject is seated with the arm supported. It is essential that the correct size of cuff is selected for the patient. For clinical measurements it is usual to measure and record both arms in the initial consultation to determine if the pressure is significantly higher in one arm than the other. The cuff is inflated until the artery is completely occluded. Using a stethoscope, we listen to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff. As the pressure in the cuffs falls, a "whooshing" or pounding sound is heard (see Korotkoff sounds) when blood flow first starts again in the artery. The pressure at which this sound began is noted and recorded as the systolic blood pressure. The cuff pressure is further released until the sound can no longer be heard. This is recorded as the diastolic blood pressure. We can also palpate/feel the radial pulse to make sure of the lower reading. The top number (the systolic blood pressure) is considered a major risk factor for cardiovascular disease for people above 50 years of age. In most people, systolic blood pressure rises steadily with age due to increasing stiffness of large arteries and long-term build-up of plaque due to unhelathy eating habits and a sedentary lifestyle. A single high reading does not necessarily mean that you have high blood pressure. However, if readings stay at 140/90 mm Hg or above (systolic 140 or above OR diastolic 90 or above) over time, this is a sign that you should start a treatment program. Such a program almost always includes lifestyle changes and often prescription medication for those with readings of 140/90 or higher. If, while monitoring your blood pressure, you get a systolic reading of 180 mm Hg or higher OR a diastolic reading of 110 mm HG or higher, wait a couple of minutes and take it again. If the reading is still at or above that level, you should seek immediate emergency medical treatment for a hypertensive crisis. Starting at age 20, it is recommended to do a blood pressure screening every 2 years. Even if your blood pressure is normal, you should consider making lifestyle modifications to prevent the development of HBP and improve your heart health.

Baroreflex Regulation of Blood Pressure, Animation.

How heart rate is controlled by the parasympathetic and sympathetic divisions of the autonomic nervous system, with overview of baroreceptor resetting.

All rights reserved. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia Baroreflex, or baroreceptor reflex, is one of the mechanisms the body uses to maintain stable blood pressure levels or homeostasis. Baroreflex is a rapid negative feedback loop in which an elevated blood pressure causes heart rate and blood pressure to decrease. Reversely, a decrease in blood pressure leads to an increased heart rate, returning blood pressure to normal levels. The reflex starts with specialized neurons called baroreceptors. These are stretch receptors located in the wall of the aortic arch and carotid sinus. Increased blood pressure stretches the wall of the aorta and carotid arteries causing baroreceptors to fire action potentials at a higher than normal rate. These increased activities are sent via the vagus and glossopharyngeal nerves to the nucleus of the tractus solitarius – the NTS - in the brainstem. In response to increased baroreceptor impulses, the NTS activates the parasympathetic system – the PSNS - and inhibits the sympathetic system – the SNS. As the PSNS and SNS have opposing effects on blood pressures, PSNS activation and SNS inhibition work together in the same direction to maximize blood pressure reduction. Parasympathetic stimulation decreases heart rate by releasing acetylcholine which acts on the pacemaker cells of the SA node. Inhibition of the sympathetic division decreases heart rate, stroke volume and at the same time causes vasodilation of blood vessels. Together, these events rapidly bring DOWN blood pressure levels back to normal. When a person has a sudden drop in blood pressure, for example when standing up, the decreased blood pressure is sensed by baroreceptors as a decrease in tension. Baroreceptors fire at a lower than normal rate and the information is again transmitted to the NTS. The NTS reacts by inhibiting parasympathetic and activating sympathetic activities. The sympathetic system releases norepinephrine which acts on the SA node to increase heart rate; on cardiac myocytes to increase stroke volume and on smooth muscle cells of blood vessels to cause vasoconstriction. Together, these events rapidly bring UP blood pressure levels back to normal. Baroreflex is a short-term response to sudden changes of blood pressure resulted from everyday activities and emotional states. If hypertension or hypotension persists for a long period of time, the baroreceptors will reset to the “new normal” levels. In hypertensive patients for example, baroreflex mechanism is adjusted to a higher “normal” pressure and therefore MAINTAINS hypertension rather than suppresses it.

A review of 1.25 million medical records of 30 year olds and older from a primary care practice for 5 years in England and looked at the different effects of systolic and diastolic blood pressure when it came to intracerebral bleeds, angina, abdominal aortic aneurysm, and renal disease. They published their results in the May issue of the journal The Lancet. It was discovered that in a 30 year old with hypertension the lifetime risk for developing cerebrovascular disease was 63% compared to 46% in those with normal blood pressure. They also found that those with hypertension developed cardiovascular disease about 5 years sooner.

The pulse is a wave of distension and elongation felt in an artery wall due to the contraction of the left ventricle forcing about 60 to 80 millilitres of blood through the already full aorta and into the arterial system. When the aorta is distended, a wave passes along the walls of the arteries and can be felt at any point where a superficial artery can be pressed gently against a bone. The number of pulse beats per minute normally represents the heart rate and varies considerably in different people and in the same person at different times. An average of 60 to 80 is common at rest. Information that may be obtained from the pulse includes: The rate at which the heart is beating. The regularity with which the heart beats occur, i.e. the length of time between beats should be the same. The volume or strength of the beat —it should be possible to compress the artery with moderate pressure, stopping the flow of blood; the compressibility of the blood vessel gives some indication of the blood pressure and the state of the blood vessel wall. The tension — the artery wall should feel soft and pliant under the fingers. Share, Support, Subscribe!!!

High Blood Pressure: Definition and Treatment
 
02:03
High blood pressure is a consistent reading of 140/90 or higher. Bethany Panchal, MD, a Family Medicine physician with Ohio State’s Wexner Medical Center, defines “consistent” as two or more readings taken days apart. When high blood pressure is considered borderline—or near that 140/90 range—changes in diet and exercise may be sufficient to lower readings. This can include a DASH or low salt diet. When readings are higher, at 150-160 range or above, medication may be added to lifestyle changes. Proper treatment is important, as high blood pressure increases the risk of heart attack, stroke and even blindness.

Hypertension - Definition, Causes, Symptoms and Treatment options
 
06:31
Hypertension - Definition, Causes, Symptoms and Treatment options In this week's video, I will be going over hypertension (high blood pressure), I will be talking about how to define hypertension, how hypertension is diagnosed, the causes of hypertension, the symptoms of hypertension and what are the certain treatment options for hypertension. Hypertension (AKA High blood pressure) is quite literally what it says on the tin, it's having the pressure in your blood vessels be too high. The normal range of blood pressure is 90-119 for systolic and 60-69 for diastolic. Hypertension can be divided into two groups, the majority of people fall into the first category, which is known as primary hypertension, this type doesn't have a cure and is a result of age and lifestyle choices. Most symptoms of hypertension do not manifest until, the pressure is very high, causing it to be known as the silent killer. When assessing a patient with newly diagnosed hypertension, you need to check that there is no damage to the organs mentioned above, 3 investigations that need to be done are funduscopic to check for any retinopathy, Urine dipstick to check for renal disease, ECG to check for left ventricular hypertrophy and Ischemic heart disease. HbA1c to check for diabetes as that is an important risk factor for cardiovascular disease and check lipids for similar reasons. The first type of treatment of hypertension is lifestyle changes, such as losing weight, exercising, eating less salt, stopping smoking etc. In terms of the medications the main classes I will speak about are diuretics, ACE inhibitors, Angiotensin 2 receptor antagonists, calcium channel blockers Blood pressure is calculated as flow (that is the volume of fluid in your vessels) times resistance. So higher flow or higher resistance leads to a higher blood pressure, as a result, most blood pressure medications work to lower either flow or resistance and thus lower blood pressure. DIruretics increase salt and water excretion, so lower the fluid volume in the body. ACE inhibitors interfere with the renin-angiotensin, aldosterone system. they stop the formation of angiotensin 2 which is a vasoconstrictor. not only that but without angiotensin 2 there is less aldosterone which normally helps to retain sodium and water, so ACE inhibitors lower resistance and flow Angiotensin 2 receptor blockers, these work in a similar fashion to ACE I but rather than stop the formation of angiotensin 2, they block the receptors for angiotensin 2. Calcium channel blockers block channels in the smooth muscles of your blood vessels, calcium normally causes these vessels to contract, so if they are blocked, the vessels will relax and have lower resistance Treatment: Step 1 less than 55 give ACEi (or ARB if can tolerate ACE), over 55 or if black give CCB (or Diuretic if can't tolerate) Step 2 CCB + ACEi/ ARB (never use ACEi and ARB together ) Step 3 ACEi/ ARBS + CCB + diuretic Sources: http://bestpractice.bmj.com/best-practice/monograph/26/treatment/step-by-step.html Passmedicine Oxford handbook of clinical medicine nice.org.uk FOLLOW ME Twitter and Instagram: Medic_Ene Twitter: https://twitter.com/Medic_Ene Instagram: https://www.instagram.com/medic_ene/ MedicEne provides a fun and different view of medical problems among other things, hope you enjoy it!

Blood pressure is simply defined as The Pressure of the Blood to the vessel wall and The Pressure of the vessel wall back to the Blood. BOP = COP x PVR Blood Pressure (BP) is equal to Cardiac Output (COP) times Peripheral Vascular Resistance (PVR). PVR can be influenced by Constriction/Dilatation of the Vessel. COP can be influenced by Stroke Volume. IT'S VERY SIMPLE! source: This is a review lecture taught by Dr Asseef in Sulaiman Al Rajhi College

High and Low Blood Pressure Symptoms and Precautions in Hindi
 
14:19
Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. When used without further specification, "blood pressure" usually refers to the arterial pressure in the systemic circulation. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature. Normal resting blood pressure in an adult is approximately 120/80 mm Hg. Blood pressure varies depending on situation, activity, and disease states. It is regulated by the nervous and endocrine systems. Blood pressure that is low due to a disease state is called hypotension, and pressure that is consistently high is hypertension. Both have many causes which can range from mild to severe. Both may be of sudden onset or of long duration. Long term hypertension is a risk factor for many diseases, including kidney failure, heart disease, and stroke. Long term hypertension is more common than long term hypotension in Western countries. Long term hypertension often goes undetected because of infrequent monitoring and the absence of symptoms.

What Causes Hypertension? I'm Dr. Frita. Did you know that high blood pressure is a leading cause of heart disease and heart failure, and the number two cause of kidney failure? __________ Subscribe so you’ll never miss my latest videos. https://www.youtube.com/channel/UCBve_ppCNE67fs3MsIocitg?sub_confirmation=1 Be sure to follow me on: Instagram: https://www.instagram.com/dr.frita/ Facebook: https://www.facebook.com/Dr.Frita Twitter: https://twitter.com/DrFrita __________ Do you know why they call hypertension the silent killer? Blood pressure. Don't let it get high off your own supply. Today, I will give a general overview of hypertension or high blood pressure. I will discuss the definition of hypertension, which actually just changed in 2017 based on the recommendations of the American College of Cardiologist and the American Heart Association. I will also talk about the consequences of poorly controlled blood pressure. And I will talk about how to prevent hypertension by not letting your blood pressure get high off your own supply. Don't let it get high off your own supply. So what is hypertension or high blood pressure? Hypertension or high blood pressure is when you have an elevated pressure in the blood vessels. We measure blood pressure with two numbers. There is that top number, or the systolic blood pressure and the bottom number, or the diastolic blood pressure. The systolic blood pressure, that top number, measures the pressure in your blood vessels while the heart is contracting or squeezing. That bottom number, the diastolic blood pressure measures the pressure within your blood vessels while the heart is relaxed. Normal blood pressure is when the systolic blood pressure is less than 120, and when the diastolic blood pressure is less than 80. You have elevated blood pressure when the systolic blood pressure is between 120 and 129, and when the diastolic blood pressure is still less than 80. So yes, with the new definitions you have elevated blood pressure when your systolic blood pressure, that top number, is between 120 and 129. So now, what is the definition of hypertension? It's when the systolic blood pressure is 130 or greater, and when the diastolic blood pressure is 90 or greater. What are the consequences of poorly controlled blood pressure? Well, heart disease, heart failure, stroke. And again, poorly controlled hypertension can lead to kidney failure. Hypertension is the second most common cause of kidney failure in the United States. What are the symptoms of hypertension? Well sure, you can get headaches. Some people will even get shortness of breath. There are different symptoms that you can get with severe high blood pressure. But the most common symptom of hypertension is nothing. So you could be walking around here with dangerously elevated blood pressures with no symptoms whatsoever, and that's why they call hypertension the silent killer. What can you do to prevent high blood pressure? Well, you can prevent it by not letting your blood pressure get high off your own supply. Don't let your blood pressure get high off your own supply. What is your own supply? Your own supply refers to the foods and the habits you have, which may be putting you at risk for hypertension. For example, if you sat down at the breakfast table and had five slices of bacon this morning, and then you checked your blood pressure and found out that it was elevated. Well, your blood pressure might be high off your own supply of bacon. What are some other things you may be supplying to your blood pressure to make it high? Number one, salt, or sodium. Don't let your blood pressure get high off your own supply of salt. Now when I ask most of my patients if they have a low salt diet, they immediately respond, "Oh yes, Dr. Frita. I never add salt to my food. I don't even pick up the salt shaker. And they're usually very proud of themselves. But once I delve a little deeper into their diet history I find that most of them have high sodium diets. So now I've given you a general overview of hypertension. We talked about the definition of hypertension. What causes Hypertension. When that top number is 130 or greater, or when that bottom number is 90 or greater. We talked about the consequences of hypertension, heart disease, stroke, kidney failure. We also talked about the most common high blood pressure symptoms. Nothing. We talked about how to prevent high blood pressure by not letting your blood pressure get high off your own supply. I want you to please comment down below. Please like my video. Share my video. And let me know whatever else you want me to discuss. I love hearing from you. Remember, prioritize yourself. Go to your doctor. Find out if you have high blood pressure, or if you're at risk. Strive to be a healthier, happier you. I'm Dr. Frita.

High blood pressure(हाई ब्लड प्रेशर का इलाज)
 
09:20
high blood pressure Blood pressure is the force exerted by the blood against the walls of the blood vessels. How great the pressure is depends on the work being done by the heart and the resistance of the blood vessels. Medical guidelines define hypertension as a blood pressure higher than 140 over 90 millimeters of mercury (mmHg). The systolic reading of 140 mmHg refers to the pressure as the heart pumps blood around the body. The diastolic reading of 90 mmHg refers to the pressure as the heart relaxes and refills with blood. The American Heart Association (AHA) defines the following ranges of blood pressure (in mmHg):   Systolic Diastolic Normal blood pressure 120 80 Prehypertension Between 120 and 139 Between 80 and 89 Stage 1 hypertension Between 140 and 159 Between 90 and 99 Stage 2 hypertension 160 100 Hypertensive crisis 180 110   If, when taking blood pressure, the reading shows a hypertensive crisis, the person should wait 2 or 3 minutes and then repeat the test. If the reading is the same or higher, this is a medical emergency. The person should seek immediate attention at the nearest hospital. Causes Blood pressure varies throughout the day. It is lower during sleep and higher on awakening. Occasionally having high blood pressure for a short time is a normal physiological response to many situations. Acute stress and intense exercise, for example, can briefly elevate blood pressure in a healthy person. For this reason, a diagnosis of hypertension normally requires several readings that show high blood pressure over time. However, a reading of 180 over 110 mmHg or higher could be a sign of a hypertensive crisis that warrants immediate medical attention. Risk factors A number of risk factors increase the chances of having hypertension. Age: Hypertension is more common in people aged over 60 years. With age, blood pressure can increase steadily as the arteries become stiffer and narrower due to plaque build-up. Ethnicity: Some ethnic groups are more prone to hypertension. Size and weight: Being overweight or obese is a key risk factor. Sex: The lifetime risk is the same for males and females, but men are more prone to hypertension at a younger age, while rates tend to be higher rate in women at older ages. Existing health conditions: Cardiovascular disease, chronic kidney disease, and high cholesterol levels are predictors for hypertension, especially as people get older. Other contributing factors include: physical inactivity a salt-rich diet associated with processed and fatty foods low potassium in the diet alcohol and tobacco use certain diseases and medications A family history of high blood pressure and poorly managed stress also contribute

Blood pressure - Medical Meaning and Pronunciation
 
00:56
Blood pressure Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called hypertension.

Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia CARDIAC OUTPUT is the amount of blood pumped by each ventricle in one minute. It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, and vice versa. For example, during physical exercises, the heart beats faster to put out more blood in response to higher demand of the body. It is noteworthy that the ventricles do NOT eject ALL the blood they contain in one beat. In a typical example, a ventricle is filled with about 100ml of blood at the end of its load, but only 60ml is ejected during contraction. This corresponds to an EJECTION fraction of 60%. The 100ml is the end-DIASTOLIC volume, or EDV. The 40ml that remains in the ventricle after contraction is the end-SYSTOLIC volume, or ESV. The stroke volume equals EDV minus ESV, and is dependent on 3 factors: contractility, preload, and afterload. Contractility refers to the force of the contraction of the heart muscle. The more forceful the contraction, the more blood it ejects. PRELOAD is RELATED to the end-diastolic volume. Preload, by definition, is the degree of STRETCH of cardiac myocytes at the end of ventricular filling, but since this parameter is not readily measurable in patients, EDV is used instead. This is because the stretch level of the wall of a ventricle INcreases as it’s filled with more and more blood; just like a balloon - the more air it contains, the more stretched it is. According to the Frank-Starling mechanism, the greater the stretch, the greater the force of contraction. In the balloon analogy, the more inflated the balloon, the more forceful it releases air when deflated. AFTERLOAD, on the other hand, is the RESISTANCE that the ventricle must overcome to eject blood. Afterload includes 2 major components: - Vascular pressure: The pressure in the left ventricle must be GREATER than the systemic pressure for the aortic valve to open. Similarly, the pressure in the right ventricle must exceed pulmonary pressure to open the pulmonary valve. In hypertension for example, higher vascular pressures make it more difficult for the valves to open, resulting in a REDUCED amount of ejected blood. - Damage to the valves, such as stenosis, also presents higher resistance and leads to lower blood output.
