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, 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, it can cause serious health issues, including brain damage or even death. The brain is particularly sensitive to low oxygen levels, and prolonged deprivation can result in irreversible harm. Prompt medical attention is crucial to restore oxygen levels and prevent complications.
