I'm a nursing student and haven't been able to wrap my head around this subject for about 2 years. Your video just made everything clicked and I feel so relieved. I can't express my gratitude enough. Thank you so much for this explanation, it was superb.
I've been an RT for many years and i found this to be the best and most easily understandable explanation of Pos. vs Neg. pressure ventilation. Excellent job!! Thank you.
I was having the most difficult time understanding this and finally threw up my hands in frustration and tears. THANK GOD I found your video!!! I can't learn by just hearing a lecture-I have to have a visual and a detailed explanation with the concept explained in various ways, usually to include an analogy (the syringe in this case.) As a nursing student, I can't thank you enough!
I know you made this a while ago BUT THANK YOU so much. I was struggling for so long to understand on the intrapleural pressure contributed to negative pressure breathing
Thank you for the great explanation! I find it enriching to know physics can help with this. P = F/A and negative pressure is when the diaphragm pulls down thus negative force.
I finally got it! TYSM! Others explained it and It still wasn’t clear and I just was not getting it. Thanks to your thorough explanation and diagram I got it. I can’t thank you enough. TY TY TY! I’m subscribing and will be liking your videos for support. 🎉
Thank you so much! Had a hard time trying to understand the subject, but this video helped me a lot, even if english isn't my first language! You explain it very well.
Hello, the interpleural pressure is always negative. It is not negative only when we contract the diaphragm, in that moment what happens is that the interpleural pressure becomes more negative
i sought out this video after wondering why a patient with atrophied lungs still required the use of an iron lung, rather than using new positive pressure ventilation systems. is it because if a persons lungs are so atrophied their natural chest wall recoil will not sufficiently create the negative pressure to deflate the lungs? thanks for this video!
Hi Tyler! You're video is great; very helpful. Can you please provide the link to the follow-up video of the different vent settings you mentioned? :)))
Hey! Great video. I just had a doubt. You said that the area between the two pleural membranes is empty. But, as of my knowledge isn't the pleural cavity between the two pleural membranes filled with pleural fluid secreted by the membranes??
hi, thanks for your video! I'd like to ask when a syringe is pushed, but not fully pushed, and there's some air inside the syringe, then may i say the the status inside syringe is still a vacuum?
In positive pressure ventilation, after the chest wall pushes back against the lungs, where does the air in our lungs exit? back through the ET tube and into the machine?
Hi, thank you for the video, it helps me understanding the subject better. Question please: If we use ambu bag or the piston as in the video, I understand that we create positive pressure for inhalation, but what happens during exhalation? Is that CO2 filling the ambu bag?
Just a note here about the relationship of pressure and volume PV = nRT the ideal gas law as the volume of lungs increase with the force of the pleura/diaphragm and the temperature of air inside the lungs is approx const pressure goes down. Due to Atmosphere pressure being constant as pressure in lungs changes air flows into lungs. The change in pressure(delta p) is negative but the pressure itself is not negative. But I guess when people say negative pressure they are actually talking about negative(delta p).
Like going off on a tangent about pleural effusion. It just got annoying and it took a while for you to get to the point. We are here for one reason; pos vs neg pressure. That's it.
+Meghan Nigro Not even. It was just an example to show how the pleural space works. You should be thanking him for a clear explanation. Unappreciative woman

8 years later still the best video on this concept, great explanation finally understood this concept thank youuuuu
9 years later too
I am an RT student , we are just being introduced to ventilatores and this is just GOLD!!!! DANKE SCHÖN!!!!!
I've been an RT for many years and i found this to be the best and most easily understandable explanation of Pos. vs Neg. pressure ventilation. Excellent job!! Thank you.
Thanks for the feedback! We are glad to hear that you enjoyed this video. Have a great weekend
Thank you brother
thanks a lot. I was rolling my eyes at first, but i watched till the end and finally get it!
What is your conclusion or summary on it? One pull one push

I am a nursing student and this was SO helpful! I appreciate you thoroughly explaining everything as you go, even the terminology, great review!
I have no formal medical education, and after watching this video I now understand the difference between the two... well done!!!! great video!
Thanks! Glad it helped
Thank you for the video! As a nursing student struggling to understand the underlying process of mechanical ventilation, this helped so much! I
The syringe analogy will help me visually understand this concept and now I won’t forget!
dope!
I bet that everybody is watching now has a physiology final tomorrow .. thanx man you made it easy !!
At first I was confused and towards the end I legit said "OHHH!!" wow that makes so much sense and much more simple than I thought. Thanks so much!
Wow, 2 years of medical school and i never understood this concept. This video is amazing thank you so much!!!!!
how are you doing now in your study ??
I wish you are getting better and better
Thank you so much! Now I understand the basic mechanics of a ventilator. This helped me big time! Thanks a lot!
Thanks for your feedback!!!much appreciated
made it clear unlike 2 years of paramedic school. thank you
I know you made this a while ago BUT THANK YOU so much. I was struggling for so long to understand on the intrapleural pressure contributed to negative pressure breathing
you rock kayla
this is great. oftentimes professors can skip the basis for concepts like this so I'm really glad i found this video
Omg thank you so much! that syringe example definitely made the explanation easier to understand and to visualize what is happening. *THUMBS UP*
That was an awesome explanation dude... The syringe example was sooo good... Thank you.. :)
+paritosh shrivatsa Paritosh, you're very welcome
Thank you

you're welcome, you're awesome
OUTSTANDING! Thank you for making this understandable. Great examples.
Omg, I just want to thank you veeeerrryyyyyy much I've been always trying to understand this, but couldn't. Thank you so much ❤❤❤❤❤❤❤❤
Thank you for the awesome explanation! The syringe example really helped me understand the content!
Such an excellent video! Straight to the point. Thank you so much😩👌🏽
I appreciate this video. I am in nursing school and this was a great explanation
Thanks, it's so clear that even a dummy like me could finally understand the difference between this two ventilation :)
Love it! It's such excellent demonstration and explanation!
Thank you so much! Had a hard time trying to understand the subject, but this video helped me a lot, even if english isn't my first language! You explain it very well.
Exmaples made it all easy ! Thank you now i get it !
Best explanation. I have always been confused about the difference between these two. The syringe demo is great.
Best video on ppv 👍🏻👍🏻
thanks!!
Super amzaing i watched alot of videos but it was very easy in providing the info that i needed
ahhhhmazing video thank you so much, was struggling to understand this concept. Happy I came across your vid!!
That was excellent and very EASY to understand!! Thank you.
Very very nice video....tnx for helping us to understand the real concept by giving such a good examples. ..gud luck
This makes so much more sense. THANK YOU
Thank you for explaining it in a simplest way.I can teach my nursing students now.Thank you so much
Great video!
Omg this is such a great instructional video!!!
Mind blowing explanation
Great explanation! Thank you.
you rock, Maria!
Thank you so much! Wow such a good explanation, you rock :)
beautiful explanation! great video sir
This Helped me with vet school! Thanks!
That was so helpful....thank you so much ❤
you're very welcome, samik! thank you
15:25 is the lightbulb moment where it all makes sense,
Wow!Very good explanation. 👏👏👏👏
beautifully explained sir
Thanks for the video!!!! Super helpful
thank you so much....it is very educative in a simple manner
Best explanation ever!
Really helpful 👍🏻👍🏻👍🏻👍🏻
Brilliant! Thank you for simplifying this.
Thank you so much , many concepts are cleared.
Awesome explanation thank you!!!! LOVE IT!!!
Hello, the interpleural pressure is always negative. It is not negative only when we contract the diaphragm, in that moment what happens is that the interpleural pressure becomes more negative
so when we exhale our intrapleural pressure is still negative? But higher than our lung pressure? Is it negative relative to the air outside the lung?
i sought out this video after wondering why a patient with atrophied lungs still required the use of an iron lung, rather than using new positive pressure ventilation systems. is it because if a persons lungs are so atrophied their natural chest wall recoil will not sufficiently create the negative pressure to deflate the lungs? thanks for this video!
you rock cassica
thanks for this... i got it now! more power to you Med school Made Easy! ; )
Amazing video!
Thank you so much that was so helpful!!!!
Thanx for this awesome video!
excellent content....never thought about this.... :-)
thanks, Andrew!
nice explanation, other videos do not talk about the intrapleural space.
Hi Tyler! You're video is great; very helpful. Can you please provide the link to the follow-up video of the different vent settings you mentioned? :)))
Great Video! Thank you.
this is a brilliant video...
Thnx a lot ths video cleared my doubts 😄
I'm trying to figure out why the iron lung man can't be using a different ventilator. Living in a capsule doesn't sound good.
You are amazing!! You explained this perfectly. Thank you!!!
Hey! Great video. I just had a doubt. You said that the area between the two pleural membranes is empty. But, as of my knowledge isn't the pleural cavity between the two pleural membranes filled with pleural fluid secreted by the membranes??
Yes ,Area between the two pleural membranes is not empty , but filled with pleural fluid , which the speaker referred to as "*pleural effusion*" .
SOOO helpful! thank you
this was such a great video.. thanks alot!!
Brilliant! Thanks.
very well explained
hi, thanks for your video! I'd like to ask when a syringe is pushed, but not fully pushed, and there's some air inside the syringe, then may i say the the status inside syringe is still a vacuum?
Great explanation
Nice sir
Thank you so much! I read about it, but it made more sense to see it here!
In positive pressure ventilation, after the chest wall pushes back against the lungs, where does the air in our lungs exit? back through the ET tube and into the machine?
yep
please .can you make avideo about difference between static and dynamic lung compliance??? and thanks alot
very nice expanation
Hi, thank you for the video, it helps me understanding the subject better. Question please: If we use ambu bag or the piston as in the video, I understand that we create positive pressure for inhalation, but what happens during exhalation? Is that CO2 filling the ambu bag?
this is what I don't understand either... If there is a closed system, how are we getting CO2 out?
Just a note here about the relationship of pressure and volume PV = nRT the ideal gas law as the volume of lungs increase with the force of the pleura/diaphragm and the temperature of air inside the lungs is approx const pressure goes down. Due to Atmosphere pressure being constant as pressure in lungs changes air flows into lungs. The change in pressure(delta p) is negative but the pressure itself is not negative.

Yes.. correct
Thank you!! 🙇♀🙇♀🙇♀
you rock, Lidiya!
Wow this was great!! Very thorough explanation. Thank you so much! :)
Nice explained
In my emt class didn’t even know there was negative pressure breathing (like a couple weeks in)
So negative is inhaling and positive is exhaling?
Thank you sir
excellent
I am so aware that I am breathing right now
Good sir
THANK YOU SOOOOOOOOOOOOO MUCH!
JUST AWESOME!!!!
Thank you
you're welcome, Rudolf!
0:43 ........... Coro.....
Oh wait, wrong year haha
🎉🎉❤tqsm
That was great
Thank u soooo much
To much excess detail for negative-positive pressure. But other than that, great video!!!!!!
