Asphyxiation is a condition caused by a lack of oxygen or an excess of carbon dioxide in the air. It occurs when the airway is blocked or when the body is unable to take in enough oxygen to sustain normal breathing. Asphyxiation can be caused by choking, strangulation, suffocation, smoke inhalation, or a medical condition such as asthma or a heart attack. It can also be caused by drowning, drug overdose, and exposure to hazardous materials. In some cases, it can be fatal.
Symptoms of asphyxiation include difficulty breathing, chest tightness, and a feeling of panic. Other symptoms may include dizziness, confusion, unconsciousness, and blue skin. If someone is suffering from asphyxiation, it is important to call for medical help immediately.
Treatment of asphyxiation depends on the cause. For example, if someone is choking, the Heimlich maneuver should be performed. If someone is suffering from smoke inhalation, oxygen should be administered. If the person is unconscious, CPR should be given until medical help arrives.
