Factors affecting oxygen uptake
Pulmonary Disease
Cardiac Shunt
Alveolar Ventilation
Affects the body’s ability to absorb the oxygen they are receiving
Factors affecting oxygen transport
Anemia Hemodilution Decreased pO2 Smoke/gas Poisoning Affect the body's ability to attach oxygen to the RBC, or to move the RBC where it needs to go.
