Video Summary:
Compliance is basically measure of extensibility of lungs. It's change in lung volume per unit change in transpulmonary pressure. It is determined by elastic force exerted by elastin and collagen fingers of lung parenchyma and surface tension of fluid lining the wall of airway. In general compliance is higher at lower lung volume and lesser at higher lung volumes.

It helped a lot. Thanks

[@krishsavani3082]

Very very nice lecture 👌

[@tahrimnisar8778]

Very nice explanation sir 🥺...thank you so much....sir can u please make a video on static and dynamic compliance...i am weak in these concepts

[@anshsinghgautam4126]

Thanks 😌😌

[@shayanfatima2522]

That was really nice

[@shubhamroy8462]

Fantastic explanation sir 👏 thanks a lot 🙏

[@NonstopNeuron]

You're most welcome

[@aan.ne___--22]

Nice

[@shaiksana1325]

Thank you so much

[@NonstopNeuron]

You're most welcome

[@charanraj9454]

Sir at starting stage of inspiration there will be more surfactant density so I think there will be a less
Surface tension please explain it sir

[@NonstopNeuron]

Yes, you are right

[@ledey70]

I couldnt underrstand this comment. Is the video wrong?

[@NonstopNeuron]

What you said is right during normal breathing. In the video the graph is started with completely collapsed lungs in which case there is no surfactant. Both are different situations. I have also shown the graph during normal breathing.

[@ledey70]

@@NonstopNeuron ah okay, I just got it now. Thank you so much sir.

[@inhkynguyen3792]

i have the same question with u guys. Thanks you Nonstop Neuron because of yoru complete answer :)) It's so amazing to be honest, I love respiratory specialist

[@amnahussain111]

0:40, but isn't pressure inversely proportional to volume? that is if transpulmonary pressure increases, shouldn't volume of lung decrease?

[@NonstopNeuron]

transpulmonary pressure = alveolar pressure - intrapleural pressure. Or in simple words it's force in direction from alveoli to pleura. So as this pressure increase, lungs expand. I hope it helps
