hypoxia
Pronunciation: hi-POK-see-ah
Medical condition characterized by insufficient oxygen levels in body tissues.
Full Definition
Hypoxia is a pathological condition in which tissues receive inadequate oxygen supply to meet metabolic demands, despite normal blood flow. It can result from various causes including lung disease, heart failure, anemia, or carbon monoxide poisoning. Hypoxia differs from hypoxemia, which specifically refers to low oxygen levels in blood. Symptoms may include shortness of breath, confusion, rapid heartbeat, and cyanosis. Chronic hypoxia can lead to serious complications including organ dysfunction and cellular damage. Treatment focuses on addressing the underlying cause and providing supplemental oxygen when appropriate. Early recognition and intervention are crucial for preventing irreversible tissue damage.
Usage
Usage note: Distinguish clearly from 'hypoxemia' which refers specifically to low blood oxygen levels.
