What Does PO2 Mean In A Blood Test?

PO2 is also known as partial pressure, oxygen. The specimen type is the blood of the human body. PO2 is a member of a panel which is known as the blood gas panel. For a specimen of blood gas, you need to use a heparinised plastic syringe which has the capacity to hold a maximum of five millilitres of blood.

There are two ranges of reference. The two ranges of reference are the arterial range of reference and the venous range of reference. The arterial range of reference has a low of 74 millimetres per hectogram and a high of 109 millimetres per hectogram. On the other hand, the venous range of reference has a low of 25 millimetres per hectogram and a high of 44 millimetres per hectogram. An ideal sample of blood should contain approximately five millimetres of whole blood. The unit which is used to measure the blood is millimetres per hectogram, which is abbreviated as mm/hg.
