Oxygen deprivation occurs when the body or a part of the body does not receive enough oxygen to function properly. This can happen due to various reasons, such as high altitudes, drowning, choking, or certain medical conditions. When the body lacks sufficient oxygen, it can lead to symptoms like confusion, shortness of breath, and fatigue. If oxygen deprivation continues for an extended period, it can cause serious damage to vital organs, particularly the brain and heart. In severe cases, it may result in loss of consciousness, brain injury, or even death. Prompt medical attention is crucial to restore oxygen levels and prevent long-term effects.
