Features: 1.Simulate standard airway opening;
2.Manual chest compression, correct compression depth (5-6cm): The compression depth is insufficient and the yellow light is on. The compression intensity is correct, the green light is on, and there is a correct beep
sound.
If the pressing intensity is too strong, the red light will turn on and an alarm buzzer will
sound. 3.Artificial mouth-to-mouth respiration (air blowing): The size of the insufflated tidal volume can be judged by observing the rise and fall of the
chest (tidal volume standard ≤500ml/600m-1000ml≤). 4.Operating frequency: International standard: 100-120 times/min, marked by a "beep" sound;
5.Operation method: training operation.
