Hypoxic hypoxia occurs when the <i>P</i>O2 of arterial blood falls. This could occur because inspired <i>P</i>O2 is lower than normal (high altitude) or it could be due to a respiratory problem (e.g., hypoventilation, diffusion impairment caused by pulmonary edema, ventilation–perfusion mismatch, or anatomic shunt of blood past the gas exchange region). In terms of O2 transport, decreased arterial blood oxygenation (hypoxemia) is the primary limitation, and thus, the problem resides with the respiratory system. Oxygen delivery is abnormal since [O2]a is less than normal. The circulatory system responds in two ways to improve tissue oxygenation.
