Manual strangulation is a form of asphyxiation where a person uses their hands to compress another person's neck. This action restricts airflow, leading to a lack of oxygen and potential unconsciousness or death. It is often associated with violent crimes and can leave physical marks on the victim's neck. The effects of manual strangulation can vary, including bruising, swelling, and damage to the trachea or carotid arteries. Victims may experience long-term health issues, such as difficulty swallowing or breathing problems. It is a serious act that can have fatal consequences if not addressed promptly.
