Functional features

Simulate standard airway opening.Manual hand position chest compression display alarm:1) The pressing position is correct, the wrong indicator light is displayed and the wrong alarm is given;2) The pressing intensity is correct (greater than or equal to 2cm area), error (less than 2cm area) indicator light display and error alarm.Mouth to mouth breathing (blowing) display alarm:1) The indicator light display and alarm when the tidal volume is less than 30ml ~ 50ml;2) The correct indicator light of the tidal volume in the range of 30ml ~ 50ml is displayed;3) If the tidal volume is too fast or too large, the gas will enter the stomach and the indicator light will display and give an alarm.Compression and artificial respiration ratio: 30:2 / single person or 15:2 / double person.Operation cycle: press and manual blowing 30:2 or 15:2 for five cycles of CPR operation.Operating frequency: International Standard: greater than or equal to 100 times / min.Operation mode: training operation.Check the brachial artery reaction: pinch the pressure ball to simulate the brachial artery pulsation.Working state: 220 V power supply.
