The sexual preference for that behavior is variously called asphyxiophilia, autoerotic asphyxia, hypoxyphilia. Colloquially, a person engaging in the activity is sometimes called a gasper. The erotic interest in asphyxiation is classified as a paraphilia in the Diagnostic and Statistical Manual of the American Psychiatric Association.

Physiology Author John Curra wrote, "The carotid arteries (on either side of the neck) carry oxygen-rich blood from the heart to the brain. When these are compressed, as in strangulation or hanging, the sudden loss of oxygen to the brain and the accumulation of carbon dioxide can increase feelings of giddiness, lightheadness, and pleasure, all of which will heighten masturbatory sensations."[1]

Author George Shuman describes the effect as such, "When the brain is deprived of oxygen, it induces a lucid, semi-hallucinogenic state called hypoxia. Combined with orgasm, the rush is said to be no less powerful than cocaine, and highly addictive."[2]

Concerning hallucinogenic states brought about by chronic hypoxia, Dr. E L Lloyd notes that they may be similar to the hallucinations experienced by climbers at altitude. He further notes that no such state occurs in hypoxia brought about by sudden aircraft decompression at altitude. These findings suggest to him that they do not arrive purely from a lack of oxygen. Upon examining the studies on hypoxia he found that "abnormalities in the cerebral neurochemistry involving one or more of the interconnected neurotransmitters, dopamine, 5-hydroxytryptamine, and β-endorphin had been reported in all the conditions associated with hallucinations."[3]

History Historically, the practice of autoerotic asphyxiation has been documented since the early 17th century. It was first used as a treatment for erectile dysfunction.[4] The idea for this most likely came from subjects who were executed by hanging. Observers at public hangings noted that male victims developed an erection, sometimes remaining after death (death erection), and occasionally ejaculated when being hanged. However, ejaculation occurs in hanging victims after death because of disseminated muscle relaxation; this is a different mechanism from that sought by autoerotic asphyxiation practitioners. Commonly, teenagers are the ones most likely to commit suicide, so in some cases autoerotic asphyxiation may be falsely ruled as suicide.[5]

Practice Various methods are used to achieve the level of oxygen depletion needed, such as a hanging, suffocation with a plastic bag over the head, self-strangulation such as with a ligature, gas or volatile solvents, chest compression, or some combination of these.[6] Sometimes, complicated devices are used to produce the desired effects.[7] The practice can be dangerous even if performed with care and has resulted in a significant number of accidental deaths. Uva (1995) writes “Estimates of the mortality rate of autoerotic asphyxia range from 250 to 1000 deaths per year in the United States.”[8] Cases have also been reported in Scandinavia[9] and Germany.[10][11]
