|
|
Cardiac Output (CO)
|
CO = HR x SV
|
|
|
Cardiac Output (CO)
|
CO = O2(Consumed)/(PulmonaryA-VO2 difference)

|
|
PAO2
|
PAO2=(760-47)FO2-(PACO2/R) |F2 = [O2], PACO2 = Av. PCO2, R = Resp Exchange Ratio CO2 produced/O2 consumed = 0.8 or 1
|
|
|
Pulm Flow
|
Flow = O2 consumed/AtoV O2 difference
|
|
|
Vel(gas) diffusion
|
Vel(gas) diffusion = Area/Thickness x Gas diffusion constant x Difference in partial pressure
|
|
|
Vent(total)

|
|
|
Compliance
|
Compliance = Vole/ Pressure
|
|
|
Pressure
