Asphyxiation occurs when the body is deprived of oxygen, leading to unconsciousness or death. This can happen due to various reasons, such as choking on food, drowning, or exposure to toxic gases. When the brain and other vital organs do not receive enough oxygen, they can suffer serious damage. Symptoms of asphyxiation include difficulty breathing, confusion, and a bluish tint to the skin. Immediate action is crucial, such as performing the Heimlich maneuver for choking victims or calling emergency services. Preventive measures, like being cautious while eating or ensuring proper ventilation, can help reduce the risk of asphyxiation.
