Transmural Pressures (transpulmonary, transthoracic, transrespiratory pressure)

[@pdiala2]

This is literally all my professor had to say, they make this so difficult when it's actually simple. Thank you

[@bluedolphin4574]

Thank you for this excellent video. Please keep making more videos like this. ❤❤❤❤❤❤❤❤❤❤❤❤❤

You are AMAZING. I used to struggle with understanding these concepts. But now, I got them! Thank you doc 🙏

[@sanketkawade2683]

Tysm sir....this video has really cleared all the doubts....now can read other stuff peqcefully

[@student4ever]

Highly conceptual ❤ Sir please add videos to the playlist like all related to respiratory system in the respiratory playlist it will help ....

Really very helpful

Best explanation,thank you

Brilliant explanation!)))

thank you so much your explanation will save me in my test

[@DrCK-mn2tb]

Very easy explanation...thank you

[@adnanshamim-3891]

thank you so much. this is amazing !!

[@hajirhameed2893]

Thank you we appreciate your efforts for understanding us the pressure in human body it's self and you demonstration it in very very simple and smart way But please in case of pneumothorax how we made this negative pressure supposed I am not in hospital How we made this negative pressure in tube we use it to treat pneumothorax ? If you make this video, I think you ll be the first one show the way which is used to generate the negative pressure to treat patients with pneumothorax? Welly it's important to know how it's work in case we asked by someone We hope you take it seriously and demonstrate it

[@dr.UmarMedLec]

Hey Hajir Hameed! Thank you for your feedback/ Let me see what can I do)

Man I love you

i think transthoracic pressure equals to intraalveolar pressure minus body surface...but u mentioned intrapleural pressure minus body surface...

[@nahlahany8967]

thanks so much that was a life saving

Can you add captions to your videos,please?

Wow Great😍👌

Very good..thanks

thank you very much!

[@abhinavajith92]

Hello guys i have a doubt. It'd be great if someone could clear it. So, Ganong says after quiet expiration the lung tends to recoil from chest wall and the chest wall tends to recoil in opposite direction which is balanced at FRC. But the transmural pressures, namely transpulmonary pressure for the lungs (usually +ve) and transthoracic pressure for the chest wall (usually - ve) is opposite to these tendencies.. This seems to give me the impression that transpulmonary pressure(almost like distending pressure) balances or counteracts the collapsing tendency while transthoracic pressure which is negative is counteracting the expanding tendency of chest wall. Is this a correct interpretation? It'd be great if anyone could shed some light on this. Thank you

[@gowthamkrishnamoorthym6897]

You are right

[@sinanshah8378]

This vedio inpired me a lot

wow, thanku

[@kitpesec1536]

Great!!!!!!!!!!

[@mansoorahmad4441]

thanks

[@ImpliedFP]

What if you take a needle and inject just enough air to make IPP not +2 but 0, would that make TPP=0 and the lung will collapse just like with pneumothorax? To get to IPP of +2, must of passed 0. Please explain.

Very helpful thanks 💜💜💜💐

[@obiwan922]

FA says in a healthy person, at FRC , transpulmonary pressure is 0 cm water. but u r saying it is +5 cm water. 03:45 I dont get it . can someone pls explain a bit?

[@thomascao6153]

bravo

[@abcd-yh8kr]

During inspiration trans thoracic pressure is dominant over trans pulmonary pressure. What does that signify?

[@survivor7070]

Can someone Tell me why the pAtm (atmospheric pressure) is zero in his equations? Normaly The pAtm is 760mmhg or am i thinking wrong???

[@anandsubramaniam4688]

Bro 1 atm is equal to 760mm of Hg

[@bitterguard5233]

It is taken as standard . Kind of like for reference purposes... it is kept as zero. Otherwise the pressure value is same

[@hawraaali1853]

When is transthorasic pressure negative .؟؟

[@ajmalminhas14]

Is transpleural and transpulmonary pressures same??

[@andrebj95]

Thank you for the video, just one question. I can't understand why atmospheric pressure is 0...shoulnd't it be 760 mmHg?

[@MorongwaMPH]

Andrea Baldazzi the reason zero is used instead of 760mmHg is that zero is a relative pressure since what matters is the difference between the pressures and not their absolute values. So you can either refer them according to their absolute or relative values atmospheric = zero relatively (760mmHg absolutely ) intralveolar/intrapumlonary = zero relatively (760mmHg absolutely) intrapleural/ intrathoracic = -4 relatively (756mmHg absolutely) hope it clears the confusion

[@andrebj95]

All clear now, thank you very much :)

[@rijakhalid9011]

According to Guyton and Hall's Physiology, 0 and -5 are measurements in cm of water. We designate 1 atm or 760 mmHg the value of 0 cmH20. So if you decrease the pressure by 5 cmH20, the pressure would become -5 cmH20. cmH20 is similar to mmHg except that Water is used in the Barometer instead of Mercury.

[@34geet]

why the all transpleural pressure is calculated on FRC???Ppleas explain

[@dr.UmarMedLec]

Hello Geet Govind! Well, because at FRC the alveoli are in direct comunication with atmospheric air. and at FRC Both have the same pressure (air and alveoli)

[@rajkumarkc1456]

Why pleural pressure is negative?

[@xiPandaaaaaa]

I believe it's due to cohesion of friction reducing "fluid" between parietal and visceral pleura, as well as the slight *suction* of lymphatic drainage (thus imagine a vacuum almost). So, when we breathe in and the ribs move up and out, the parietal pleura moves with the ribs (as it is attached to the thoracic wall) causing the volume of the pleural cavity to increase meaning pressure decreases (see Boyle's law). I hope this helps! This is how I make sense of it.

[@rajkumarkc1456]

@@xiPandaaaaaa thank u sooo much

[@divyaprasad7215]

@@xiPandaaaaaa the pleural pressure is negative even when the lungs are at resting state.( due to reasons such as lymphatic drainage , differential growth of the chest cavity and lungs in foetus , etc) During inspiration it becomes more negative , owing to an increase in intrathoracic cavity volume as the chest expands as u mentioned.
