Combined with 2010 international standard cardiopulmonary resuscitation, the product features a comprehensive upgrade. CPR training can be carried out, with the electronic light display, compression depth when blowing volume and cardiac compressions detected artificial respiration. CPR training to adapt to the society CPR training institutions, hospitals, medical school, medical school and other medical units, simple, inexpensive. Standard: American Heart Association (AHA) 2010 International cardiopulmonary resuscitation (CPR) & Emergency Cardiovascular Care (ECC) guidance standard features: 1, analog standard airway open. 2, manual chest compressions correct compression depth (> 5cm): press the intensity is too small, yellow light; pressing strength is correct, the green light, and beep indicating correct; press the intensity is too large, the red light??? and an alarm beep indication; 3, artificial mouth to mouth breathing (blowing): blown tidal volume size by observing the ups and downs of the chest to determine (tidal volume standard ≤500ml / 600ml-1000ml≤)?. 4, the operating frequency: the latest international standards: 100 beats / min, in order to "drop" sound as the symbol. 5, operation: training operations. 6.
