What causes stagnant hypoxia?

Stagnant hypoxia occurs when there is an inadequate blood supply to tissues, leading to insufficient delivery of oxygen to meet the metabolic needs of those tissues. This condition can arise from various factors that impair blood circulation, such as heart problems, shock, or any condition that affects blood flow. As a result, even if oxygen content in the blood is normal, the lack of proper circulation means that oxygen is not effectively delivered to the body's cells.

Understanding the underlying mechanisms of stagnant hypoxia is important for recognizing the symptoms and taking appropriate measures in aeromedical situations. Conditions that may contribute to stagnant hypoxia include decreased cardiac output and physical factors, such as prolonged stationary positions that impede blood flow.
