Pinching people is sometimes a good first aid method. This kind of situation is mostly "unconsciousness", "fainting" and "going against the wind", which is what western medicine often says. It is an emergency caused by various epidemic pathogens or stroke, epilepsy, phlegm syndrome or asthma developing to a certain extent, which leads to the inversion of qi and blood and the obstruction of qi.

The human brain is the most sensitive place to oxygen and energy, and the slightest problem will give you color, so all tissues of the human body will have a good mechanism to coordinate and ensure that oxygen and energy are supplied to the brain at the first time. Once there is brain hypoxia, body regulation will start immediately to ensure normal blood supply to the brain, and people will wake up in a short time.

For patients with syncope, the first thing to do is to judge the patient's vital signs. If not syncope, but coma, cardiac arrest, respiratory arrest, can not wake up in a short time, the patient needs immediate cardiac resuscitation. If it is syncope, let the patient lie flat or face down, increase the blood supply to the brain, raise the mandible, ensure the unobstructed respiratory tract, and insist on whether there is trauma when the patient syncope, call 120 as soon as possible and send him to the hospital as soon as possible. In western medicine, patients will actively treat the causes of syncope after waking up.

People who pinch people usually lean their heads on themselves, or let the patient's head lower to ensure the airway is unobstructed. The patient will wake up after a while, so all the people who pinch people can wake up by themselves. If they are really in a coma, CPR will be much more reliable.

You can't pinch people in everything, it will harm patients.
