hypoxia
Tissue oxygen deprivation
Hypoxia is a deficiency of oxygen reaching body tissues.
The condition ranges from mild (causing confusion or shortness of breath) to severe (causing organ damage or death).
Climbers at high altitude risk hypoxia from thin air.
Medical contexts distinguish hypoxia from anoxia, the complete absence of oxygen.
The patient showed signs of hypoxia after the cardiac arrest.
