Pulmonary Volumes and Capacities Flashcards
SaO2
Percent saturation of hemoglobin of oxygen in arterial blood
PCO2
Partial pressure of carbon dioxide
Palv
Alveolar pressure
Functional residual capacity
ERV + RV
This capacity is the amount of air that remains in the lungs at the end of normal expiration (about 2300 milliliters).
PAO2 and PACO2 in alveolar capillaries
PAO2 = 100mmHg
PACO2 = 40mmHg
PO2 and PCO2 in systemic circulation at site of cells
PO2 = 40mmHg
PCO2 = ~46mmHg
Dyspnea
Shortness of breath or air hunger
VO2
Rate of oxygen uptake per minute
SO2
Percent saturation of hemoglobin with oxygen
Label pulmonary values for men and women
VCO2
Amount of CO2 eliminated per minute
PvCO2
Partial pressure of CO2 in venous blood
PaO2 and PaCO2 in arterial blood
PaO2 = 95mmHg
PaCO2 = 40mmHg
Eupnea
Normal or quiet breathing
CvO2
Total concentration of oxygen in venous blood
