Detailed explanation-1: -Hypoxemic hypoxia Hypoxemia can be caused by lung and heart diseases, congenital heart defects, and medications that slow your breathing. Traveling to a high altitude, where levels of oxygen are lower, can also cause hypoxemia.
Detailed explanation-2: -Several factors influence the binding of oxygen to hemoglobin: temperature, pH, PCO2 and 2, 3 diphosphoglycerate (2, 3 DPG). Increasing the temperature of Hb lowers its affinity for O2 and shifts the oxygen dissociation curve to the right, as shown in Figure 3.
Detailed explanation-3: -Hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).
