I was literally in depression since last 3 days because I couldn't understand this topic.....I went through Physiology to Medicine books....but was a hell lot confused....Then I saw your videos about pressure,compliance and DLCO....I was relieved....No one can explain like you...I repeat no one....I just can't thank you enough.....Wish to meet you once in my life.....Lots of love and respect...From India🙏🙏🙏🙏

[@MedicosisPerfectionalis]

My dear student...This is why I do what I do...Reading your comment made me ao happy 😃...Thank you so much 😊

I believe I am too blessed to have visited this video. The last time I was this thankful to God was probably when I made it to med school :D

[@MedicosisPerfectionalis]

I am so thankful for your comment, dear :) Can you please help me by sharing?

[@jessicakaushal3327]

Medicosis Perfectionalis of course Sir :)

[@greensahuaro2834]

I once had an old man for substitute teacher in high school. Substitute teachers don't teach anything but stay in classroom as a guardian. But I never forgot what he said about learning! He said:" If you make learning fun, it is easier to learn"! So, you not only teach objective matter; but indirectly, you help us learn easier by making us laugh. So, you are doing more than teaching. You are making life fun. Thank you so much! I can picture you in a comedy show on TV! "Laughter is the best medicine"!

[@MedicosisPerfectionalis]

I appreciate you so much!

[@Chaudharys1]

This is the best lecture ever in pulmonology I have had. I am so grateful.

1-Your videos are wonderful specially biochimistry playlist it helped me a lot thx 2- our teacher asked us why the intrapleural pressure is negative from the beginning (he wasn't talking about its variations)

[@MedicosisPerfectionalis]

Thank you so much 😊

[@MedicosisPerfectionalis]

Thank you so much ☺️

[@MuhammadShoaib-dw4yu]

So you explained beautifully the concept of intrapleural and intrathoracic pressures . My question is that if pressure in any intrathoracic structure like ivc trachea esophagus must be equal to intrapleural pressure then why does the esophagus looks a *bit collapsed* than trachea on CAT scan images .Like you explained intrapleural pressure is the same in the esophagus ..

[@drinaciofernandes]

i was searching for a mnemonic for PLUMMER VINSON and your video came up about the italian wife . hahaha it was amazing. already subscribed earlier to your channel but i dont receive updates so i hit the bell icon . keep making the amazing videos

[@MedicosisPerfectionalis]

What about patients that have undergone pleurectomy? How does this affect the venous return and such?

[@stardust8361]

You're amazing, thank you so so much! 💓

[@MedicosisPerfectionalis]

My pleasure 😇

[@supriyodeb1828]

During inspiration, the chest wall expands, but so do the lungs, so where the lungs and chest wall moving opposite direction that makes the intraplural pressure more -ve ?

[@akabdurahman]

4:12 HOW CAN YOU HEAR MY INSIDE VOICE looooool

[@argumentumadbaculum]

Thanks a lot. As always you teach great.

[@MedicosisPerfectionalis]

So simply explained..thankyou🙏

[@MedicosisPerfectionalis]

My pleasure 😇

[@khadijah3343]

What do you mean when yu state the positive intrapleural pressure will push the mediastinum to the negative side?

[@sarahbakri1067]

you are amazing, thank you so much

[@MedicosisPerfectionalis]

You’re very welcome ☺️

[@justdoit8075]

During inspiration, the intrapulmonary pressure becomes negative so that the air can move in. At the same time, the chest wall is expanding which means an outward force on the chest wall. If the lungs and chest wall are moving in the same direction, how can the intrapleural pressure become MORE negative during inspiration? Or is it that even though the lungs are expanding, the pressure is actually in the opposite direction?

[@issakhan2000]

Thanks for making this so easy

[@MedicosisPerfectionalis]

My pleasure 😇

[@rehanaahmad5419]

Really uh are great ☺️

[@Dr.SheldonShelby]

Just awesome..saw so many videos but none at your level ...you and your videos are legendary...hats off to your fun and easy explanation 🙌🏼🙌🏼🙌🏼🙌🏼❤️

[@MedicosisPerfectionalis]

Thank you, dear!

[@malamin1549]

may i ask question is the Intrapleural pressure necessary for alveoli ? if we just cancel the Intrapleural pressure is the ventilation will absolute lost ? in case the answer is yes ، so how we kapt the lung out side the body in case of lung transplant

[@gojames1239]

Thank you!

[@MedicosisPerfectionalis]

My pleasure 😇

[@khadijah3343]

As intrapleural pressure is between -5cm-7cmH2O from which region of the lung are these values from?

[@kondayugandhar9748]

Absolutely amazing explanation 😍😍

Thank you so much 😊

[@dorukd.3814]

Hello, there is a feeling of pressure, tightness and shortness of breath in the upper lobe of the right lung, which has become chronic, a tomography was taken, nothing came out, what else can I do?

Great video, you just have the signs backwards on the alveolar pressures during inspiration and expiration.

[@MedicosisPerfectionalis]

Andrew You're right. They are the other way around.
