[0002] Pulmonary resuscitation is a life-saving technique for cardiac and respiratory arrest. Its purpose is to restore the patient's spontaneous breathing and circulation. The rescuer allows air to enter the lungs of the rescued person rhythmically through mouth-to-mouth, and then squeezes the rescued person's chest cavity and uses the elastic recoil of the chest and lung tissue to exhale the gas that has entered the lungs. This cycle is repeated to replace spontaneous breathing, and can effectively rescue people after their heart and breathing have stopped.

[0003] Referring to CN216456400U, a new type of artificial respirator is disclosed. The technical solution thereof mainly includes a balloon, a bottom plate and a squeezing mechanism for squeezing the balloon. The balloon is connected to a mask, a detector for monitoring breathing is arranged inside the mask, and the squeezing mechanism includes a telescopic rod electrically connected to a controller, and a pressing plate is connected to the telescopic end of the telescopic rod, and the pressing plate is arranged on the side of the balloon facing away from the bottom plate. The utility model has the following beneficial effects: the emergency personnel place the mask cover on the patient's mouth and nose, and control the breathing volume and breathing frequency by controlling the telescopic length and telescopic frequency of the telescopic rod, so as to carry out targeted rescue.
