Recently, a black man in Minnesota, USA, died after being "neck pressed" by the police, according to an independent autopsy report issued by the black man's family, which was mainly due to suffocation caused by neck and back compression. So, here we have to talk to everyone about science, how long will it take to suffocate and lose consciousness?
First of all, human respiratory organs include the nose, pharynx, larynx, trachea, bronchi, and lungs. When people's respiratory tract is blocked for various reasons, resulting in insufficient oxygen in the lungs and no function of ventilation at all, it is called suffocation. Foreign bodies in the airway or the absence of an external source of oxygen, which eventually cause the lungs to be unable to breathe, are the causes of asphyxiation.
When the human body is severely hypoxic, the organ tissues in the body will be widely damaged and necrotic due to continuous lack of oxygen, especially the brain. Suffocation for 4 to 6 minutes may appear coma, and when the air in the lungs is completely depleted, the trachea is blocked and can not breathe, as long as 1 minute, there will be a phenomenon of cardiac arrest. If this time is rescued in time, the airway blockage is lifted, and breathing is restored, then the heartbeat will also beat again.
Clinically, asphyxia is divided into mechanical asphyxia, toxic asphyxia, pathological asphyxia, central respiratory arrest caused by cerebral circulation disorders, neonatal asphyxia and asphyxia due to lack of oxygen in the air.
Of course, there are many causes of suffocation, and first aid for suffocation should be based on its cause. The cause of airway obstruction and hypoxia is relieved, and some patients can recover quickly. However, asphyxia is one of the most important causes of death for critical illness. Therefore, in daily life, everyone needs to pay more attention. If there are small children at home, we must eliminate the safety hazards of the family in time to prevent accidents. #Medical Federation Media Super Group ##清风计划 #
