Oxygen Transport Flashcards
1
Q
What is cooperative binding?
A
Increased affinity of hemoglobin for oxygen as more oxygen binds with it
2
Q
What is the bohr effect?
A
The shifting of the hemoglobin oxygen dissociation curve.
3
Q
What are the 8 steps in the oxygen cascade?
A
Inspiration and air quality, airway, lungs and chest wall, diffusion, perfusion, myocardial function, peripheral circulation, and tissue extraction.

Q
What is Exercise Induced Arterial Hypoxemia?
A
A decrease in oxygen saturation greater than 3-4% below resting levels during exercise
