Why does a person wake up when he or she is strangled?

Raise blood pressure

Blood pressure is one of the important life indicators of human body, and low blood pressure can be life-threatening. Pinching can stimulate the blood pressure to rise and ensure the blood supply to all organs of the body in critical situations to maintain the normal operation of life activities.

Strengthening breathing exercise

Breathing is also one of the important vital indicators of the human body. Pinching the Renzhong point can stimulate respiratory movement, and proper rhythmic stimulation can cause continuous inspiratory excitation, which is conducive to strengthening rhythmic respiratory activity. The thumb tip can be used to pinch the Renzhong point, 20-40 times per minute, lasting 0.5-1 second each time.

When to pinch

After excluding cardiac arrest, the patient may faint due to heat stroke (deficiency, sweating, etc.), stroke (dizziness and fall, unfavorable speech, distorted mouth and eyes, etc.), or shock (cold skin, pale and rapid heartbeat, etc.), and can be rescued by pinching. First aid, whether it is pinching or CPR, the first time should immediately call the 120 emergency number.

Cardiac arrest should not be pinched

If a person is in cardiac arrest, there is no therapeutic effect, so if he or she is pinched, it will only waste the golden rescue time. If someone faints and shows symptoms such as loss of consciousness, no pulsation of the aorta, enlarged pupils, purple skin, and no thoracic movement, it is a sign of cardiac arrest, and cardiopulmonary resuscitation should be performed immediately.

The risk of awakening by pinching

Causing respiratory arrest

When pinching, weak stimulation at the side can cause continuous inspiratory excitation, and strong stimulation at the side can cause continuous inspiratory depression, and both inspiratory excitation and inspiratory depression caused by the side stimulation may lead to the suspension of respiratory activity.

Causing asphyxia

The jaw should be elevated when pinching, if the jaw is pressed down together, it will aggravate the backward fall of the tongue root and lead to airway obstruction. Some people coma is often accompanied by vomiting, vomit should be cleaned up in time, otherwise pinching will cause vomit airway reflux, resulting in asphyxia.
