What term means without oxygen and is synonymous with suffocation?

The term that means "without oxygen" and is synonymous with suffocation is anoxia. Anoxia refers specifically to a state where there is a deficiency of oxygen in the tissues, which can lead to serious health consequences, including loss of consciousness and death, if not addressed quickly. In medical contexts, anoxia highlights the critical need for adequate oxygen delivery to cells for survival. This condition can arise from various situations, such as drowning, choking, or respiratory failure, all of which prevent the body from obtaining the necessary oxygen. The recognition of anoxia is vital in health care, as swift intervention can often reverse its effects.
