Question 1

Definition oxygen-hemoglobin dissociation curve

Answer 1

The bohr effect describes hemoglobin lower affinity for O2 secondary to an increase on CO2 or decrease on PH (acidosis)x
This decrease affinity enhances the unloading of oxygen into tissues to meet O2 demand of the tissues.

Question 2

Mechanisms of hypoxemia

Answer 2

1- hypoventilation
2- decrease oxygen % in inspired air
3- perfussion ventilation missmatch
4-diffussion impairement
5-intrapulmonary shunt
