normal PAO2
100 mmHg
when the inspired air is 100% saturated 37 degrees and holds
44 mg/L maximum humidity
47 mmHg water pressure
when combined - diffusion constant is - times faster than -
CO2
20
O2
PV=
nRT
- only moves gas from one location to the other
ventilation
R& n are - therefore are eliminated from the equation
constant
equilibrium of gas concentrations are usually accomplished in about - seconds, a total transit time in the capillaries would be -
0.25
0.75
the - the tissue the more difficult the diffusion
thicker
fluid within the lungs creates greater distance for gases to transfer through
pulmonary edema
Altitude elevation will cause a - in gas concentration in the air this causes a - in partial pressure of gases
decrease

barometric pressure (Pb) always migrates to -

what things can affect diffusion

normal PCo2 (Arterial blood)
35-45 mmHg

transpulmonary and transairway pressure changes created by diaphragm
measures the amount of CO diffuses across the ACM into blood
diffusion capacity of carbon monoxide (DLCO)
if you bypass upper airway way you decrease the...

water in a gaseous form =
water vapor or molecular water
the amount of blood flow
