Strangulation
Strangling is compression of the neck that may lead to unconsciousness or death by causing an increasingly hypoxic state in the brain. Fatal strangling typically occurs in cases of violence, accidents, and is one of two main ways that hanging causes death (alongside breaking the victim's neck). Strangling does not have to be fatal; limited or interrupted strangling is practised in erotic asphyxia, in the choking game, and is an important technique in many combat sports and self-defense systems. Strangling can be divided into three general types according to the mechanism used: * Hanging—Suspension from a cord wound around the neck * Ligature strangulation—Strangulation without suspension using some form of cord-like object called a garrote * Manual strangulation—Strangulation using the fingers or other extremity General Strangling involves one or several mechanisms that interfere with the normal flow of oxygen into the brain: *Compression of the carotid arteries or j ...

Strangulation In Domestic Violence
Strangulation in the context of domestic violence is a potentially lethal form of assault. Unconsciousness may occur within seconds of strangulation and death within minutes. Strangulation can be difficult to detect and until recently was often not treated as a serious crime. However, in many jurisdictions, strangulation is now a specific criminal offense, or an aggravating factor in assault cases. Differences from choking Although sometimes the words are used interchangeably, "strangulation" and "choking" are not the same thing. Choking is when air flow is blocked by food or a foreign object in the trachea – something that can be addressed by the Heimlich maneuver. Strangulation, by contrast, is defined by reduced air flow and/or blood flow to or from the brain via the intentional external compression of blood vessels or the airway in the neck. Notably, however, many victims of strangulation refer to the assault as "choking". Both manual strangulation (i.e., gripping the thro ...

Hanging
Hanging is the suspension of a person by a noose or ligature around the neck.Oxford English Dictionary, 2nd ed. Hanging as method of execution is unknown, as method of suicide from 1325. The ''Oxford English Dictionary'' states that hanging in this sense is "specifically to put to death by suspension by the neck", though it formerly also referred to crucifixion and death by impalement in which the body would remain "hanging". Hanging has been a common method of capital punishment since medieval times, and is the primary execution method in numerous countries and regions. The first known account of execution by hanging was in Homer's ''Odyssey'' (Book XXII). In this specialised meaning of the common word ''hang'', the past and past participle is ''hanged'' instead of ''hung''. Hanging is a common method of suicide in which a person applies a ligature to the neck and brings about unconsciousness and then death by suspension or partial suspension. Methods of judicial hanging T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Choking Game
The choking game or blackout challenge is the act of intentionally cutting off oxygen to the brain with the goal of inducing temporary loss of consciousness and euphoria. Reasons for practice Limited research has been conducted regarding motivations for practicing the fainting game, although thrill seeking has been identified as a risk factor, as has the perception that it is a low-risk activity. Anecdotal reasons stated include: * Peer pressure, a challenge or dare, a rite of passage into a social group or amusement over erratic behavior. * Curiosity in experiencing an altered state of consciousness, the experience of a greyout, or an imagined approximation to a near-death experience. * A belief that it can induce a brief sense of euphoria (a rushing sensation or high). * The prospect of intoxication, albeit brief, at no financial cost. Reasons for practice are distinct from erotic asphyxiation. Steve Field, chairman of the Royal College of General Practitioners in London, cl ...

Erotic Asphyxia
Erotic asphyxiation (variously called asphyxiophilia, hypoxyphilia or breath control play) is the intentional restriction of oxygen to the brain for the purposes of sexual arousal. The term autoerotic asphyxiation is used when the act is done by a person to themselves. Colloquially, a person engaging in the activity is sometimes called a ''gasper''. Erotic asphyxiation can lead to accidental death due to asphyxia. The erotic interest in asphyxiation is classified as a paraphilia in the ''Diagnostic and Statistical Manual'' of the American Psychiatric Association. Physiology Concerning hallucinogenic states brought about by chronic Hypoxia (medical), 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.

Garrote
A garrote or garrote vil (a Spanish word; alternative spellings include garotte and similar variants''Oxford English Dictionary'', 11th Ed: garrotte is normal British English spelling, with single r alternate. Article title is US English spelling variant.) is a weapon, usually a handheld ligature of chain, rope, scarf, wire or fishing line, used to strangle a person.Newquist, H.P. and Maloof, Rich, ''This Will Kill You: A Guide to the Ways in Which We Go'', New York: St. Martin's Press, (2009), pp. 133-6 Assassination weapon A garrote can be made out of many different materials, including ropes, cloth, cable ties, fishing lines, nylon, guitar strings, telephone cord or piano wire.Whittaker, Wayne, ''Tough Guys'', Popular Mechanics, February 1943, Vol. 79 No. 2, pp. 44Steele, David E., ''Silent Sentry Removal'', Black Belt Magazine, August 1986, Vol. 24 No. 8, pp. 48–49 A stick may be used to tighten the garrote; the Spanish word refers to the stick itself.

Carotid Sinus
In human anatomy, the carotid sinus is a dilated area at the base of the internal carotid artery just superior to the bifurcation of the internal carotid and external carotid at the level of the superior border of thyroid cartilage. The carotid sinus extends from the bifurcation to the "true" internal carotid artery. The carotid sinus is sensitive to pressure changes in the arterial blood at this level. It is the major baroreception site in humans and most mammals. Structure The carotid sinus is the reflex area of the carotid artery, consisting of baroreceptors which monitor blood pressure. Function The carotid sinus contains numerous baroreceptors which function as a "sampling area" for many homeostatic mechanisms for maintaining blood pressure. The carotid sinus baroreceptors are innervated by the carotid sinus nerve, which is a branch of the glossopharyngeal nerve (CN IX). The neurons which innervate the carotid sinus centrally project to the solitary nucleus in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyoid
The hyoid bone (lingual bone or tongue-bone) () is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra. Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. It is the only bone in the human body that is not connected to any other bones nearby. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Its name is derived . Structure The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns. Body The body of the hyoid bone is the central part of the hyoid bone. *At the front, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asphyxia
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects primarily the tissues and organs. 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. In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths. The word asphyxia is from Ancient Greek "without" and , "squeeze" (throb of heart). Causes Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; envir ...

Air Hunger
Shortness of breath (SOB), also medically known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct sensations, the degree of distress and discomfort involved, and its burden or impact on the patient's activities of daily living. Distinct sensations include effort/work to breathe, chest tightness or pain, and "air hunger" (the feeling of not enough oxygen). The tripod position is often assumed to be a sign. Dyspnea is a normal symptom of heavy physical exertion but becomes pathological if it occurs in unexpected situations, when resting or during light exertion. In 85% of cases it is due to asthma, pneumonia, cardiac ischemia, interstitial lung disease, congestive heart failure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
