Strangling is compression of the neck that may lead to unconsciousness or death by causing an increasingly hypoxic state in the brain. [1] 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).

Contents

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: [2]

General

The neck contains several vulnerable targets for compression including the carotid arteries. Gray513.png
The neck contains several vulnerable targets for compression including the carotid arteries.

Strangling involves one or several mechanisms that interfere with the normal flow of oxygen into the brain: [3] [4]

Depending on the particular method of strangulation, one or several of these typically occur in combination; vascular obstruction is usually the main mechanism. [5] Complete obstruction of blood flow to the brain is associated with irreversible neurological damage and death, [6] but during strangulation there is still unimpeded blood flow in the vertebral arteries. [7] Estimates have been made that significant occlusion of the carotid arteries and jugular veins occurs with a pressure of around 3.4 N/cm2 (4.9 psi), while the trachea demands six times more at approximately 22 N/cm2 (32 psi). [8]

As in all cases of strangulation, the rapidity of death can be affected by the susceptibility to carotid sinus stimulation. [5] Carotid sinus reflex death is sometimes considered a mechanism of death in cases of strangulation, but it remains highly disputed. [3] [9] The reported time from application to unconsciousness varies from 7–14 seconds if effectively applied [10] to one minute in other cases, with death occurring minutes after unconsciousness. [3]

Manual strangulation

Manual strangulation (also known as "throttling") is strangling with the hands, fingers, or other extremities and sometimes also with blunt objects, such as batons. Depending on how the strangling is performed, it may compress the airway, interfere with the flow of blood in the neck, or work as a combination of the two. Consequently, manual strangulation may damage the larynx [3] and fracture the hyoid or other bones in the neck. [5] In cases of airway compression, manual strangling leads to the frightening sensation of air hunger and may induce violent struggling. [3]

Manual strangulation is common in situations of domestic violence, [11] and is regarded by experts as an especially severe form of domestic violence, due to its extremely frightening and potentially lethal nature, and an observed correlation between non-fatal strangulation in domestic violence and future homicide. [12]

Manual strangulation also has a history as a form of capital punishment, during the 18th century, a sentence of "Death by Throttling" would be passed upon the verdict of a Court Martial for the crime of desertion from the British Army. [13]

More technical variants of manual strangulation are referred to as strangleholds, [14] or chokeholds (despite the term "choke" more technically referring to internal airway restriction), and are extensively practised and used in various martial arts, combat sports, self-defense systems, and in military hand-to-hand combat application. In some martial arts like judo, Brazilian jiu-jitsu, and jujutsu, when applied correctly and released promptly after loss of consciousness, strangleholds that constrict blood flow are regarded as a safer [15] means to render an opponent unconscious, when compared to other methods, especially strikes to the head, the latter of which can cause potentially catastrophic or fatal and irreversible brain injuries much more quickly and unpredictably. [16]

Ligature strangulation

Ligature strangulation (also known as "garroting") is strangling with some form of cord such as rope, wire, chain, or shoelaces, either partially or fully circumferencing the neck. [17] Even though the mechanism of strangulation is similar, it is usually distinguished from hanging by the strangling force being something other than the person's own body weight. [5] Incomplete occlusion of the carotid arteries is expected and, in cases of homicide, the victim may struggle for a period of time, [5] with unconsciousness typically occurring in 10 to 15 seconds. [17] Cases of ligature strangulation generally involve homicides of women, children, and the elderly. [5] Compared to hanging, the ligature mark will most likely be located lower on the neck of the victim.

During the Spanish Inquisition, victims who admitted their alleged sins and recanted were killed via ligature strangulation (i.e. the garrote) before their bodies were burnt during the auto-da-fé . [18] Throughout much of the 20th and 21st centuries, the American Mafia used ligature strangulation as a means of murdering their victims. Confessed American serial killer Altemio Sanchez used ligature strangulation in the rapes and/or murders of his victims, as did the Gary Ridgway (the Green River Killer), and British serial killer Dennis Nilsen. [19]

Incaprettamento is a method of strangulation in which the victims neck is tied to their legs bent behind their back (similar to hogtie), so that the victim effectively strangle themselves. This method was common throughout Neolithic Europe, and occurred for over two thousands years in northern and southern Europe, as evidenced by skeleton remains. It's uncertain why it was so common, but researchers speculate a person bound in this way might be considered to have strangled themselves, versus being killed by someone else. Victims may have been part of a ritual sacrifice. Rock art in Addaura Cave, in Sicily, made between 16,000 and 13,000 BP, depict two human figures bound in the incaprettamento manner. Today, it is a method of homicide mostly associated with the Italian Mafia, who have used it as a ritual warning or reprimand. [20] [21]

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 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.

Hanging is killing a person by suspending them from the neck with a noose or ligature. Hanging has been a common method of capital punishment since the Middle Ages, and is the primary execution method in numerous countries and regions. The first known account of execution by hanging is in Homer's Odyssey. Hanging is also a method of suicide.

A chokehold, choke, stranglehold or, in Judo, shime-waza is a general term for a grappling hold that critically reduces or prevents either air (choking) or blood (strangling) from passing through the neck of an opponent. The restriction may be of one or both and depends on the hold used and the reaction of the victim. While the time it takes for the choke to render an opponent unconscious varies depending on the type of choke, the average across all has been recorded as 9 seconds.

The choking game, or fainting game is the act of intentionally cutting off oxygen to the brain with the goal of inducing temporary loss of consciousness and euphoria. A related internet challenge, the blackout challenge, encourages the use of the choking game online.

A carotid-cavernous fistula results from an abnormal communication between the arterial and venous systems within the cavernous sinus in the skull. It is a type of arteriovenous fistula. As arterial blood under high pressure enters the cavernous sinus, the normal venous return to the cavernous sinus is impeded and this causes engorgement of the draining veins, manifesting most dramatically as a sudden engorgement and redness of the eye of the same side.

Grappling holds are used principally to control the opponent and to advance in points or positioning. The holds may be categorized by their function, such as clinching, pinning, or submission, while others can be classified by their anatomical effect: chokehold, headlock, joint-lock, or compression lock. Multiple categories may be appropriate for some of these holds.

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.
