Hypoxia refers to a condition in which there is a deficiency of oxygen in the tissues or cells of the body. This lack of oxygen can lead to various physiological issues because oxygen is crucial for cellular metabolism and energy production. When cells do not receive adequate oxygen, they may not function optimally, and in severe cases, it can result in cell death or organ damage. Understanding hypoxia is vital in healthcare as it may occur in various situations, such as respiratory illnesses, high altitudes, or conditions that impair blood flow. Recognizing the signs and symptoms of hypoxia is important for providing appropriate care and intervention.
