oxygen deprivation
Lacking breathable air
Oxygen deprivation is a shortage of oxygen reaching the body's tissues.
The brain is especially vulnerable—even brief deprivation can cause permanent damage or death.
The condition occurs through drowning, choking, smoke inhalation, high altitude, or medical emergencies.
The climbers carried supplemental oxygen to prevent oxygen deprivation.
Also called hypoxia in medical contexts.
