According to the American Heart Association, bronchoscopy is a reliable method used to visualize the cause of choking when not resolved via oxygen and supportive care. [23] Bronchoscopy also is a crucial tool in foreign body removal after supportive care has been provided and the person who is choking is stable. [24]
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position.

The person applying then laces his closest arm around the back of the head, and places his entire body weight against the neck, causing both air constriction, and restriction of blood flow to the brain.

Carotid sinus syncope is due to pressure on the carotid sinus in the neck. [2] The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3]
