What causes asphyxia?
Asphyxia, or a deficiency of oxygen, can be caused by a variety of factors. Common causes include choking, drowning, suffocation, smoke inhalation, and drug overdoses. Other causes include respiratory diseases, cardiac arrest, blocked airways, and high altitude. In some cases, asphyxia can occur due to a lack of oxygen in a person's environment, such as in a poorly ventilated room or in a confined space such as an underground mine. In addition, asphyxia can be caused by the body's inability to utilize oxygen properly, such as in the case of severe asthma attacks.
