Asphyxiation methods refer to techniques that lead to a lack of oxygen in the body, resulting in suffocation. Common causes include choking, drowning, and the inhalation of toxic gases. These methods can occur accidentally or intentionally and can lead to serious health consequences or death if not addressed promptly. In emergency situations, recognizing the signs of asphyxiation, such as difficulty breathing or loss of consciousness, is crucial. First aid measures, like the Heimlich maneuver for choking, can help restore airflow. Understanding these methods is important for prevention and effective response in critical situations.
