I. Identification of Cardiac Arrest
Beat the patient’s shoulders and call the patient loudly on the ear side:
If there is no response
Place the head side above the patient’s head, the ear above the patient’s face, and look at the patient’s chest to observe whether the chest and abdomen fluctuate.
If there is no fluctuation
Go to the next step
II. Call Emergency System
Call 120, clarify the location and set aside the passage.
Three, start chest compressions
Overlap your hands, the palm root of the lower hand is placed in the lower half of the sternum, and the pressing position is about the two transverse fingers on the xiphoid process. Overlap your hands, vertically downward, and quickly press 30 times, 100-120 times per minute, each time 5-6 cm.
4. Open airway
Place one hand on the patient’s forehead
Lift the bony structure of the lower jaw with the index and middle fingers of the other hand.
The line between the corners of the mouth and the earlobe is vertical to the ground.
Five, artificial respiration
Hold the patient’s nose with your hand;
Blow air into the patient’s mouth for about 1 second;
After seeing the patient’s chest and abdomen ups and downs, it can stop.
Perform artificial respiration twice, return to the third step, and continue chest compressions.
6. Extracorporeal defibrillation
Defibrillation can stop a variety of ineffective heart beats and is a common method used by doctors to save patients with cardiac arrest. At present, a device called automatic external defibrillator is already available to ordinary people. If there is an automatic external defibrillator nearby, defibrillation can be started as follows:
After the defibrillator arrives, place the electrode sheet on the patient;
Press the analysis button and do not touch the patient during analysis.
If defibrillation is not recommended, return to the third step to continue chest pressure. If defibrillation is recommended, leave the patient and press the electric shock button.
After defibrillation is completed, repeat steps 3-4-5 in sequence for 5 consecutive cycles, and then judge whether defibrillation needs to be continued.
