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

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)
