1.What happen to PH ,PO2 and PCO2 of blood when you inject room air into vein while drawing blood into a syringe ?

2. If you draw blood from vein ( ex: femoral vein) what will be its PH, PO2 AND PCO2 while compared to arterial blood ?

1. How much air? A 10 ml syringe, no Effect.

2. Venous PO2=40, PCO2=45, pH=7.2?

Q1. potentially can lead to air embolism..
Q2 Blood gas composition of femoral vein will be similar to that of mixed venous blood i.e.,
PO2 = 40 mmHg
PCO2 = 46mmHg
pH = 7.4

If this was a potential answer on the test, I would probably pick it, but from a practical standpoint, it would have to be a lot of air, that's why I asked.

here u go...

:arrow: 1. blood will show increased PO2 ,decreased PCO2 and increased PH.

:arrow: 2.venous blood will have PO2 less (when compared to artery) ,
increased PCO2 and decreased PH (when compared to artery)
