Understand mechanical ventilation with this clear explanation by Dr. Roger Seheult of http://www.medcram.com. Includes a discussion on simplifying the different modes of ventilation (based on volume, pressure, rate, flow, O2, CPAP) and other ventilator basics. This is video 1 of 5 on mechanical ventilation.

An update to tidal volume. It is no long get 8 ml/ kg ideal body weight. It is now about 6-8 so 8 would be the max tidal volume. I choose the middle 7 so you can go up a bit and down a bit. The slightly lower tidal volumes are to protect the lungs. Max is now 8
This helped a lot. I took CCP in the summer and that was the hardest class I've ever taken so far. I still struggled to understand the basics of the vent and so far your video has helped cleared some cob webs lol.
Hi Medcram, I have throughly enjoyed listening to your videos on ventilation. I have an interest in producing educational videos and just wondered if you might be able to tell me which software you use to produce your handwritten videos? Any tips or further information you might be able to share about your creative process would be very gratefully received. Many thanks, FreeAnaestheticTutorials
+Kayla Roberts Continuous mandatory ventilation (CMV) is a mode of mechanical ventilation in which breaths are delivered based on set variables. ... Thus, today's CMV would have been called ACV (assist-control ventilation) in older nomenclature, and the original form of CMV is a thing of the past. Wikipedia- Continuous mandatory ventilation.
Great stuff, I am an ICU RN and am always learning new concepts, procedures and perspectives...still, the face pace to the ICU leaves me little time to quietly ponder and dissect all the information, and that's were these short videos really help me grasp the concepts fully. Bottom line, many thanks!
If AC is set volume....what is AC/PC. In the unit right now and one of the patients is on AC/PC with set pressure control and tidal volume is the dependent variable. This presentation, however, says tidal volume is fixed in AC.
Please note that AC does not imply volume ventilation. AC refers to the breath trigger as was explained. The breath can be cycled or terminated via volume, pressure, flow control, or adaptive/hybrid controls. It's a matter of what starts the mechanical or machine-delivered breath vs what ends it. It should not be assumed that AC is only used during volume ventilation and is somehow different from or unrelated to pressure ventilation.
erebusnux121 this sounds like PRVC which is a volume targeted mode that limits the pressure to 5 below the set upper pressure alarm limit. This mode is wonderful because it protects the lungs, but also allows for a targeted volume.
There are a few factors in sleep apnea treatment. One place I discovered which succeeds in merging these is the Stans Slumber Method (google it if you're interested) without a doubt the most useful resource that I've seen.Check out all the amazing info .
You make it seem so easy. That's awesome even tho is not easy at all. :) I am a new ICP and my portfolio includes ICU and CCU. I find ventilation very challenging for now but hey, I just started on my own a Week ago. Soon I'll have to start the CLI and VAP program. I read CDC and PIDAC documents. Any help there? Thank you.
Pulmonary compliance (or lung compliance) is a measure of the lung's ability to stretch and expand. In clinical practice it is separated into two different measurements, static compliance and dynamic compliance. Static lung compliance is the change in volume for any given applied pressure.
Where have you been all of my nursing life! I work in a pediatric vent facility with amazing RT's who try their best to explain settings/modes/ functions to me, but since I have them, I never found it necessary to 'know it all'. Now that I care for a baby at home on mechanical ventilation, although my education/experience has taught me everything that I need to know care for him, I just want to 'know it all' !! You explained mechanical ventilation in such a way that, now, my RT's smile in amazement when we converse ;-) thank you so much!
I had to create a you tube channel to make a comment / request .... Please do a video on ICP head injuries / meningitis In the critical care setting ... I'm a 4semester RN student wish there were more of your great videos ... Thanks!
