Partial Pressures of the Respiratory Gases

thank you a lot!this really helped

Nice man...very simple and clear cut.

There are some wrong values

Read the same 20 slides today over and over for more than an hour, couldn't make sense of it. 5 minute video and perfect picture. Thanks!

Thank you very much! I found this really useful and you explained it clearly.

Great video but there is one thing I don't understand. Why exactly does the pO2 in the alveola remain constant at 100 mmHg even though oxygen diffuses into the blood. And why does the pO2 in the tissue remain constant at 40 mmHg even though oxygen diffuses there. Like why does it not increase ?

Thank you. Explained clearly. I need a favour. What software did you use to create the figures and presentation?

Thank you sir

thanx <3

wow thanks!!

thank youu it was so helpful

Supper wonderful explanation
I wanna ask why the pression of o2 I tracheal airs from 150 to 100 in alveolar cuz of dead spaces ??

Thank you! That was really informative 🤍

Superb ! God bless you 😇

Woahh thanks sooo much.... I understood it now. You explained it sooo well. Thank you!!!

Hi Thank you for your video! I have a question about something that is been confusing me so much and I haven’t found an answer to, when you say PaO2 in blood is that in the gaseous state or liquid state( dissolved)? If dissolved then how come it’s 100 mmHg and the solubility of oxygen is only 0.003? Also I read that the partial pressure of oxygen in plasma is equal to the dissolved and undissolved oxygen does that mean (100mmhg of oxygen + 100mmhg*0.003)?
Thank you very much in advance.

Sir for oxygen po2 160mmhg to 150mmhg-----decreased by humidification
But pco2-o.3(atmp air) to alveoli pco2-40mmhg
Sir my doubt is how co2 increased??

Thanks it helped
