Asphyxia, also known as suffocation, is a type of death that occurs when a person is deprived of oxygen. It is a medical emergency that can occur when a person's oxygen supply is interrupted or cut off completely. The most common cause of asphyxia is choking, though it can also be caused by drowning, electric shock, smoke inhalation, and other forms of suffocation. In some cases, asphyxia can even be caused by a lack of air, such as in a vacuum or in a sealed room.
Symptoms of asphyxia include difficulty breathing, confusion, dizziness, loss of consciousness, and eventually death. In some cases, the person may experience a heart attack or stroke as a result of the asphyxia.
Treatment for asphyxia depends on the underlying cause. If the person is choking, the Heimlich maneuver can be performed to remove the foreign object from the airway. If the person is drowning, CPR may be necessary to restore breathing. For smoke inhalation, oxygen therapy may be necessary to increase oxygen levels in the blood.
In many cases, asphyxia can be prevented. To reduce the risk of choking, avoid eating large pieces of food or talking while eating. If you are in a space with limited air or a vacuum, be sure to wear a mask to protect your airway. Finally, always be aware of your surroundings and be aware of possible sources of smoke inhalation.
