Thank you so much! I just graduated as a doctor and no-one has ever taken time to explain this to me properly and i really struggled finding resources on it! Super helpful thank you!
PaO2 is the O2 partial pressure in the arterial blood, PAO2 (capital "A") is the partial pressure of O2 in the alveoli. I noticed you used the wrong one in the video and they are not equivalent (cf.the Aa gradient). Be careful it can get very confusing if you start switching them up!
"This is an alveoli." Actually, it's an alveolus (singular) :-) Otherwise, a much needed clarification for what is often poorly understood. What is needed is to integrate the amount (volume) of oxygen transport capacity, i.e. hemoglobin. An anemic/hemorrhagic patient will have the same PaO2 and SaO2 readings, but have a total reduction of oxygen volume. For example an SaO2 of .98 x 1.34 (coeff) x 15Hb = 19.7 mL O2/dL The same SaO2 of .98 x 1.34 x 7Hb = 9.2 mL O2/dL. Despite an unchanged PaO2 and SaO2, the oxygen volume is 50% less.

Oh wow you have just the right voice and delivery of a great instructors/professor/teacher well done:)...kept me listening
Finally someone "actually" explained these PaO2 and FiO2 .
Tnx Doctor 🙏🙏🙏
I am not a nurse, still i am benefiting from this beautiful video.
Thank you. ☺
Best video on Pa02

well done Max ,,, I’ve noticed that as well
PAO2 is Alveolar oxygen, PaO2 is arterial Oxygen. There is formula for that gradient: A-a.
Thank you so much for an explanation clear enough for a lay person!
This video is incredible. Thank you!
thanks a lot ,,, you’ve made so clear ,,, salute
This. Was. Amazing. Thank you 🙏🏻
This is really great thank you!
you are great teacher. thank you
I wish I had your ad a professor when I was in nursing school Tx!!
thank you very much, that was really helpful
Big Thanks.
