This guy deserves an award. One of the best medical teaching videos of all time

[@ZeroToFinals]

Thanks!

[@highdopamine29]

dear students or whoever anaphysio maybe confusing but to be very honest, in real practice u will understand it, u will learn to connect things once u encounter real patient during clinicals.. good luck

Thank you sir, explanation is so good.

[@TheWeirdF]

Also worth mentioning adjusting for FiO2 when interpreting PaO2. Very roughly, a normal PaO2 is FiO2 - 10. So if FiO2 is 80%, then a so-called "normal" PaO2 is actually profoundly hypoxic.

[@ZeroToFinals]

Good point!

[@championssportsagency3540]

When you run a ABG, you will have to enter FIo2 and temperature so your results are taking those in consideration

Thanks, a great video. Additionally, a method of assessing appropriate oxygenation is 5×FiO2, if PaO2 is below that means imapired oxygenation

This is a very informative data. However, I do have a question. What would indicate an underline of a medical problem if your blood work shows a low level of "pO2 (v) POC" at 25 mmHg in ref. to the average between 80 - 105 mmHg? Symptoms are shortness of breath, weakness in body upon exertion. Resting seems help. Thank you! BTW, do we need this test as well?

My step son is in ICU on a ventilator & ECMO machine. He has Covid & a severe bacterial pneumonia. Psuedomonis and Klebsiella. He's pretty sick. His lungs are full of clots. They did a bronchoscopy & found his chest tube has punctured his airway. He's a mess. I feel so helpless.

so sorry to hear that. it does feel helpless but just being there is what goes a very long way. how is he doing now?

[@janethrees9907]

They fool you by telling you these manufactured gases are in the atmosphere Just need to look at the processes they use to “extract” them to see it’s not an extraction process Look up patents for oxygen and nitrogen production Eg Carbon filters that give required concentrations of carbon to nitrogen
