The explanation is thorough, with the perfect speed and enthusiasm, which makes this video a success. I could feel your passion as you were reviewing the concepts that were previously explained and it's the kind of nonchalance that makes your tone agreeable and the viewer more comfortable. Finally, thank you for making the video, it's clear that it took you a lot of time and effort to produce, I hope our sincere comments will make the latter worth it.
I am so lucky to have found this channel, dude your videos are a piece of art. It’s so great of you to do so much work and spreading your knowledge on this platform. I hope you keep making more videos, because honestly whenever I study some topic ,I am like I have to visit your channel and see the actual explanation. Kudos¡
Excellent video, but it seems that "work of expiration" is not just limited to those with pulmonary problems - indeed, it is the normal function for trained singers! Would love to see you do a video on the pressure-relaxation curve - thanks!
I literally get overwhelmed and frustrated with medical school every new unit with the flood of information. And then I watch your videos and enjoy it again. You make learning these concepts a lot of fun.
Thank you so much for amazing content, as always! I had a question about the work of breathing I was hoping you could please answer... in COPD, the resistance is higher so to decrease the work of breathing, I read that they breathe slower and deeper to decrease resistance. Why is that? What is the physics relationship between resistance and velocity of air in lungs (fast breathing versus slow breathing). Thank you so much in advance!
Can you please explain this, sir? In the pressure- volume graph when we consider the gradient as compliance, isn't it higher in 'lungs only' than in 'lungs+ chest wall' ? So, why won't the compliance is higher in ' lungs only' than that of the combined system?
Please help In gyton’s book ,I read that (the compliance of the combined lungthorax system is almost exactly one half that of the lungs alone) .and can’t match it with what you mentioned here about differences between compliance of lungs and lung with chest wall ......... thanks
In pneumonectomy, Doesn’t the decrease in intrathoracic pressure cause the diaphragm to pull downwards to accommodate the increase in volume? If not, why not?
Thank you for these great videos and your great explanation..i have a question and i will be very thankful if you answer (i know that surfactant lines the alveoli and it gives it the tendency to get smaller because of its surface tension so why surfactant opposite surface tension ?)
Pleural pressure is same as transpulmonary pressure, just change the sign. This is valid only when intrapulmonary P. is 0, right? That is at the beginning and end of inspiration/expiration.
In inspiration as alveolar volume increases, surfactant density decreases therefore leading to increasing surface tension and thereby lessening compliance. That means that as the curve proceeds the slope should be going down rather than up right ? But then how come the inspiration plot is sloping upwards with increasing inspiratory volume ?
Medicosis, thank u for this amazing video! At 17:00 tho, I think it should be like this: Compliance lung only = Compliance chest wall only (they both should be 2 L / kPa) > Compliance lung + chest wall (which should be 1 L / kPa) right?
Yeah I think so too. That should be true as compliance is the gradient of the pressure- volume curve and clearly it's seen that gradient is lower in the combined system than that of lungs only or chest wall only . And may be the gradients of lung and chest wall are the same.✌

Hi, I am an Italian medical student (pardon for my english) ! I have a question: why did you change the pressure into positive values ? I've searched on lots of sites and I didn't understand why the pressures are positive. Don't we have negative pressures in the lungs at the beginning of inspiration ? The negative pressure is useful in order to let the air flow in the lungs,. Thank you so much !
17:05 If lungs alone have a tendency to collapse, so surfactant molecules are accumulating i.e. conc of surfactant increases 11:01, decreased surface tension, increased compliance. So shouldn't the compliance be on higher side for lungs alone??? I think the answer lies in the analogy that lungs alone have increased tendency to collapse, and when placed alone they start collapsing, now if we try to fill the collapsing lung with air, they would resist the filling, so decreased compliance Similarly when chest wall alone is placed, they have a tendency to expand, and they start expanding, and now while expansion when we try to fill the chest wall with air, they take up air very easily and expand even faster, hence highly compliant, so max compliance. Is this the right line of thinking plzz explain???

My new favorite channel. Love the humor hahaha
Why have I only discovered this channel?! One video in and I would sacrifice my life for this guy 😂 best explanation ever
Thank you so much 😊
AS a medical device sales this is an amazing video very informative,educational and easy to understand
Thank you 😊
Awesome video ❤
Really appreciated 🙏
I had recommend this channel to all my friends
Thank you so much!
Thank you for this informative video....can you explain pressure and volume curves of the heart please and thank you
You are save the doctors life's big love from iraq♥️
You are saving ****
Why I'm feeling U R from baghdad 🙃🙃?
Thanks alot it was amazing 💪❤️

What is the difference between static and dynamic pressure-volume curves?
Please help
In gyton’s book ,I read that (the compliance of the combined lungthorax system is almost exactly one half that of the lungs alone) .and can’t match it with what you mentioned here about differences between compliance of lungs and lung with chest wall ......... thanks
Thank you so much ♥️🙏
My pleasure 😇
Outstanding 🙏🙏🙏
Thank you 😊
thank you sir !! you save me every single semester ,, plz make videos about endocrine system soon ..
Thank you so much 😊
I will try
In pneumonectomy, Doesn’t the decrease in intrathoracic pressure cause the diaphragm to pull downwards to accommodate the increase in volume? If not, why not?
Huge thanks sir ❤
My pleasure 😇
Thank you for these great videos and your great explanation..i have a question and i will be very thankful if you answer (i know that surfactant lines the alveoli and it gives it the tendency to get smaller because of its surface tension so why surfactant opposite surface tension ?)
It’s a fact in physics that surfactant decreases surface tension...Please watch my video on surfactant.

hi, nice video. isnt the compliance for lung only, greater than lung + chest wall, since it's slope is greater?
I think it should be like this: Compliance lung only = Compliance chest wall only (they both should be 2 L / kPa) > Compliance lung + chest wall (which should be 1 L / kPa)
Okay.. We will not confuse with flow volume loop😂
Awesome 👏
why in the beginning of expiration the curve is flat?
Thank.you.sir.
My pleasure 😇
Is relaxation pressure and pressure volume means same?
Can not find pulmonary playlist. Please add link to this video

Hilarious Lecture!🤣
Thank you so much 😊
@@MedicosisPerfectionalis ❤
So you're saying the pressure volume loop and flow volume loop are the same thing, right? Thanks!
No, they are not! 😊
Your are gem +funny🥰
how does having no surfactant leads to increased surface tension? mechanism...?
Great question.

Negative pressure 👌💥💥
Hi, I am an Italian medical student (pardon for my english) ! I have a question: why did you change the pressure into positive values ? I've searched on lots of sites and I didn't understand why the pressures are positive. Don't we have negative pressures in the lungs at the beginning of inspiration ? The negative pressure is useful in order to let the air flow in the lungs,.
Thank you so much !
Which part of the lecture? Can you give me the timestamp? (i.e. at which minute and second)?
@@MedicosisPerfectionalis thank you for the reply, I've understood it later !
Sir excellent teaching but just wanted to ask that are u a Vietnam veteran
Thanks 🙏
No, I am not.
I'm here to save my academic year 😤
I wish you success!
Why conpliance is high for expiration?
Have you watched my video titled “compliance”?
Do u use magic¿ how could u make it so easy¿
Thank you so much ☺️
Does obesity affect plateau pressure?
I wish UA-cam removes ad from educational videos.
And how will I put food on my table? 😭😢

Won't intrinsic lung disease cause decreased elasticity ?
Elasticity is the opposite of compliance. In restrictive lung disease (including intrinsic), compliance is low, whereas elasticity is high.
17:05 If lungs alone have a tendency to collapse, so surfactant molecules are accumulating i.e. conc of surfactant increases 11:01, decreased surface tension, increased compliance. So shouldn't the compliance be on higher side for lungs alone???
I think the answer lies in the analogy that lungs alone have increased tendency to collapse, and when placed alone they start collapsing, now if we try to fill the collapsing lung with air, they would resist the filling, so decreased compliance
Similarly when chest wall alone is placed, they have a tendency to expand, and they start expanding, and now while expansion when we try to fill the chest wall with air, they take up air very easily and expand even faster, hence highly compliant, so max compliance.
Is this the right line of thinking plzz explain???
