That depends on whether you are asking about the red blood cells themselves, or the blood as a whole. The fluid portion of the blood will have a O2 partial pressure around 20%, but the red blood cells will have an O2 partial pressure nearing 100%.
Pulmonary artery/Systemic veins
PCO2 = 45
PO2 = 40
Pulmonary vein/Systemic arteries
PCO2 = 40
PO2 = 100

The partial pressure of oxygen in expired air is 109 mmHg. Partial pressure is calculated at the proportion of oxygen in the air, so at 1 atmosphere for dry air pressure is 713 mmHg (which is 760 total pressure - 47 mmHg water vapor) and oxygen is 21% of the dry gas concentration so inspired pO2 is 150 mmHg.

Because of difference in partial pressure
C02:alveoli
pco2 is partial pressure of o2 in the capillary and paco2 is partial pressure of co2 in the arteries. So, one is a measurement of O2 and the other is CO2
a falling blood PH and a rising partial pressure of carbon dioxide due to pneumonia or emphysema indicates?
metabolic acidosis
The concentration of Carbon Dioxide in arterial blood. Partial (Pa) Carbon Dioxide (CO2) pressure in ABG.
You can consume up to ten times as much oxygen in exercise as at rest, and produce the same increase in CO2.
PaO2 is the partial pressure of oxygen in arterial blood. Pa is the abbreviation of partial.
