What is a form of asphyxia resulting from external pressure on the neck?

Strangulation is specifically defined as a form of asphyxia that occurs when external pressure is placed on the neck, restricting airflow and blood flow to the brain. This can happen in various situations, such as during assaults or domestic violence encounters, where someone might be intentionally applying pressure to the throat. The result of such pressure leads to a deprivation of oxygen, potentially causing unconsciousness or death if not relieved quickly.

In contrast, suffocation generally refers to asphyxia caused by a lack of oxygen in the environment or by obstruction of the airways due to other means, while choking often involves an object blocking the airway from within. Breath-holding is a voluntary action where a person consciously stops breathing, which is also distinct from strangulation as it does not involve external pressure on the neck. Understanding these definitions is vital for recognizing the different causes and mechanisms of asphyxia in various scenarios.
