However, researchers explain that people who receive concentrated oxygen may be at risk of oxygen toxicity or oxygen poisoning. WebThe amount of pressure exerted by carbon dioxide dissolved in the blood is known as the partial pressure of carbon dioxide, or pCO2, according to Eastern Kentucky University. In healthy people, the normal level of pCO2 is 35mm to 45mm of mercury, says Orlando Regional Healthcare.

The Fick equation (see Chapter 18) defines CO2 elimination from the lungs (Vco2) as: (V co2) = (V aFaco2)- (V iFico2), where Vco2 is the difference between the CO2 expired from the alveoli and the amount of CO2 inspired to the alveoli. Fico2 is nearly zero, so the inspired terms can be dropped. highly rated virginia beers
