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.

8 years later still the best video on this concept, great explanation finally understood this concept thank youuuuu

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 am an RT student , we are just being introduced to ventilatores and this is just GOLD!!!! DANKE SCHÖN!!!!!

thanks a lot. I was rolling my eyes at first, but i watched till the end and finally get it!

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

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 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!

The syringe analogy will help me visually understand this concept and now I won’t forget!

I have no formal medical education, and after watching this video I now understand the difference between the two... well done!!!! great video!

Thank you for the video! As a nursing student struggling to understand the underlying process of mechanical ventilation, this helped so much! I

Wow, 2 years of medical school and i never understood this concept. This video is amazing thank you so much!!!!!

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.

Thank you so much! Now I understand the basic mechanics of a ventilator. This helped me big time! Thanks a lot!

I bet that everybody is watching now has a physiology final tomorrow .. thanx man you made it easy !!

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. 🎉

made it clear unlike 2 years of paramedic school. thank you

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!

Omg thank you so much! that syringe example definitely made the explanation easier to understand and to visualize what is happening. *THUMBS UP*

this is great. oftentimes professors can skip the basis for concepts like this so I'm really glad i found this video

That was an awesome explanation dude... The syringe example was sooo good... Thank you.. :)

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 ❤❤❤❤❤❤❤❤

15:25 is the lightbulb moment where it all makes sense,

Thank you for the awesome explanation! The syringe example really helped me understand the content!

Thanks, it's so clear that even a dummy like me could finally understand the difference between this two ventilation :)

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.

Such an excellent video! Straight to the point. Thank you so much😩👌🏽

Best video on ppv 👍🏻👍🏻

Super amzaing i watched alot of videos but it was very easy in providing the info that i needed

Great video!

I appreciate this video. I am in nursing school and this was a great explanation

Exmaples made it all easy ! Thank you now i get it !

Omg this is such a great instructional video!!!

Best explanation. I have always been confused about the difference between these two. The syringe demo is great.

Great explanation! Thank you.

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

Thank you for explaining it in a simplest way.I can teach my nursing students now.Thank you so much

Thank you so much! Wow such a good explanation, you rock :)

That was so helpful....thank you so much ❤

That was excellent and very EASY to understand!! Thank you.

Mind blowing explanation

Great video thanks

Love it! It's such excellent demonstration and explanation!

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

Thanks for the video!!!! Super helpful

ahhhhmazing video thank you so much, was struggling to understand this concept. Happy I came across your vid!!

I am so aware that I am breathing right now

Nice sir

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!

0:43 ........... Coro..... Oh wait, wrong year haha

Wow!Very good explanation. 👏👏👏👏

In my emt class didn’t even know there was negative pressure breathing (like a couple weeks in)

This Helped me with vet school! Thanks!

Really helpful 👍🏻👍🏻👍🏻👍🏻

beautifully explained sir

beautiful explanation! great video sir

Thank you so much that was so helpful!!!!

Brilliant! Thank you for simplifying this.

thank you so much....it is very educative in a simple manner

Awesome explanation thank you!!!! LOVE IT!!!

thanks for this... i got it now! more power to you Med school Made Easy! ; )

Thank you!! 🙇‍♀🙇‍♀🙇‍♀

Thank you so much , many concepts are cleared.

Best explanation ever!

Amazing video!

Thank you sir

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).

nice explanation, other videos do not talk about the intrapleural space.

Thanx for this awesome video!

Fantastic video!

Great Video! Thank you.

Brilliant! Thanks.

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.

Good sir

Thank you

excellent content....never thought about this.... :-)

SOOO helpful! thank you

excellent

this is a brilliant video...

Thnx a lot ths video cleared my doubts 😄

🎉🎉❤tqsm

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??

this was such a great video.. thanks alot!!

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? :)))

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?

please .can you make avideo about difference between static and dynamic lung compliance??? and thanks alot very nice expanation

To much excess detail for negative-positive pressure. But other than that, great video!!!!!!

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?

very well explained

You are amazing!! You explained this perfectly. Thank you!!!

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

So negative is inhaling and positive is exhaling?

THANK YOU SOOOOOOOOOOOOO MUCH!

JUST AWESOME!!!!

❤❤❤❤❤

Wow this was great!! Very thorough explanation. Thank you so much! :)
