Q

pCO2

A

The partial pressure (tension) exerted by CO2 in mmHg. The respiratory
component. Carbon dioxide (CO2) is
produced by metabolism and carried by the
blood to the lungs where it diffuses into the alveoli and is eliminated by exhaled breath. The amount of CO2 dissolved in the blood is measured by the partial pressure it exerts and is reported in mmHg. When CO2 dissolves in H2O it combines to form H2CO2 (carbonic acid) the most important acid in the body.
The [H2CO2] is directly proportional to the CO2 dissolved in the blood (paCO2)
and the paCO2 is a measurement of the ventilation status of the patient.
Therefor the paCO2 is known as the respiratory
component of the acid-base
balance. As with pH, the body maintains the pCO2 within strict limits. The normal pCO2 is 35-45 mmHg with a mean of 40 mmHg.

Q

pO2

A

partial pressure of oxygen; Oxygen is used by the body as a metabolic
substrate to produce energy. A constant
supply of oxygen is needed to maintain
living tissue. 21% of the air we breath is oxygen and at sea level it exerts a pO2 of ~159 mmHg. The air is taken into lungs with each inhalation and moved into the alveoli where the pO2 is
~100 mmHg. The O2 diffuses into the blood
and dissolves in the plasma where it exerts a pO2 of ~95 mmHg. In normal arterial blood with a pO2 of ~95 mmHg the blood is ~98% saturated with oxygen.
The oxygen is carried to the tissue by the blood and by the time the venous blood returns to the lungs it has a pO2 of ~40 mmHg and is ~75% saturated. The paO2 is assessed on the ABG to provide a measure of the arterial oxygenation.
