Strangulation
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.
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".
Manual strangulation (i.e., gripping the throat with one’s hands) is the most common method of strangulation in intimate partner violence, although ligatures (e.g., belts, scarves) are sometimes used.
