Question 1

What is the alveolar air equation

Answer 1

PAO2 = [FiO2 (Patm – PH2O)] – [PaCO2 / R]

Where
PA02=partial pressure of O2 in alveoli
F102=fractional [] of 02 in inspired air
P1=Pressure of inspired air
PH20=Partial pressure of water
PaCO2= Partial pressure of CO2 in arterial blood
RQ=respiratory quotient
