Asphyxia

Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing.[3] [4] Asphyxia causes generalized hypoxia, which affects all the tissues and organs, some more rapidly than others. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death.

9.8 million unintentional worldwide (2015)[1]

35,600 worldwide (2015)[2]

In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths.[1][2] The word asphyxia is from Ancient Greek α- "without" and σφύξις sphyxis, "squeeze" (throb of heart).[5]

Acute respiratory distress syndrome

such as that from a car exhaust and the smoke produced by a lit cigarette: carbon monoxide has a higher affinity than oxygen to the hemoglobin in the blood's red blood corpuscles, bonding with it tenaciously, and, in the process, displacing oxygen and preventing the blood from transporting oxygen around the body

Carbon monoxide inhalation

Contact with certain chemicals, including (such as phosgene) and blood agents (such as hydrogen cyanide)

pulmonary agents

Drowning

Drug overdose

Exposure to extreme low pressure or from spacesuit damage (see space exposure)

vacuum

whether suspension or short drop hanging

Hanging

Self-induced by hyperventilation, as in shallow water or deep water blackout and the choking game

hypocapnia

Inert gas asphyxiation

or primary alveolar hypoventilation, a disorder of the autonomic nervous system in which a patient must consciously breathe; although it is often said that people with this disease will die if they fall asleep, this is not usually the case.

Congenital central hypoventilation syndrome

Respiratory diseases

Sleep apnea

A which stops breathing activity

seizure

Strangling

Prolonged exposure to

chlorine gas

Stand behind the affected person and wrap your arms around him/her.

Push inwards and upwards under the ribs with a sudden movement by your second hand.

If the performed actions were not effective, repeat them until you free respiratory tract of the affected person from a foreign body.

If there are symptoms of mechanical asphyxia, it is necessary to call the Emergency Medical Services.[22] In some countries, such as the US, there may also be self-acting groups of voluntary first responders who have been trained in first aid.[23] In case of mechanical asphyxia, first aid can be provided on your own. In such a situation, you need to do the following:

 – Nontoxic or minimally toxic gas which can displace oxygen in breathing air

Asphyxiant gas

 – Intentional restriction of oxygen to the brain for sexual arousal

Erotic asphyxiation

 – Abnormally high tissue carbon dioxide levels

Hypercapnia

 – Medical condition

Respiratory acidosis
