The operating steps of two types of cardiopulmonary resuscitation simulators are provided for your reference.

1. Single-person rescue:

Step 1. First lay the simulator flat and then perform 30 correct chest compressions by a single person (the display shows 30 compressions on the monitor).

Step 2. Tilt the head back 70-90 degrees to open the airway, and blow manually for 2 times correctly (correct blowing is displayed as 2 on the monitor).

Step 3. Continuously perform 30 correct chest compressions and 2 correct artificial respirations (i.e. 30:2) for five cycles (including one cycle of steps ① and ②).

Step 4. Finally, the correct pressure is displayed as 150 on the monitor, and the correct blowing is displayed as 10. It is reported that the single-person operation is successful according to the program, and there is a voice prompt: "Operation is over", music is played automatically, the carotid artery pulses continuously, the heart automatically makes a sound of resuming beating, and the pupils automatically shrink from the original dilation, indicating that the person has been Save.

2. Double rescue:

Step 1. Lay the simulator flat, and then perform double chest compressions 30 times (displayed as 30 on the monitor).

Step 2. Tilt the head back 70 to 90 degrees to clear the airway and blow air manually 2 times correctly

Step 3. Repeat the first and second operations four times (press 30 blows 2 times).

Step 4. Finally, the correct pressing number on the monitor is 150, and the correct blowing number is 10. That means the double cardiopulmonary resuscitation operation is successful, and there will be a voice prompt: "First aid successful." Automatically playing music, the carotid artery continuously pulsates, the heart automatically emits the sound of resuming beating, and the pupils automatically shrink from their original dilation, indicating that the person has been saved.

The current new version of cardiopulmonary resuscitation operation guidelines are: C-artificial circulation (chest compressions), A-airway opening, B-artificial respiration.
