The act of intentionally impeding blood flow and/or airflow to the brain via external pressure to the neck results in a rapid loss of consciousness. Time to incapacitation is influenced by the method used and the amount of force applied. Research indicates that cessation of consciousness can occur within seconds when significant pressure is exerted on the carotid arteries, which supply blood to the brain, or when the trachea is compressed, preventing breathing.
Understanding the physiological mechanisms involved in such actions is crucial in fields such as forensic science and medicine. Precise timing and force analysis can provide essential information in investigations. Historically, the methods and effects have been a subject of study related to violent crime, self-defense, and even certain medical procedures where controlled pressure on the neck might be necessary.
