CPR manikin feature:
1) Clearly anatomic characteristic, realistic touch feeling and lifelike skin color, vivid appearance
2) Can perform artificial respiratory, extracardial compression and airway open
3) Operation mode: CPR training, can perform compression and inflation

CPR instrument feature:
1) Indicator show inflation volume, correct inflation volume: 30ml- 50ml; Fast ventilation > 30ml within 0.27 seconds indicated by red light. When the inflation volume is excessive, proper, indicators will accordingly be yellow, green, and alarm will ring accordingly
2) Indicator show compression depth: correct compression depth: approximately 13mm-20mm When the compression depth is proper or excessive, indicators will accordingly be green, yellow, and alarm will ring accordingly
3) Indicator show compression position: Right compression position indicated by red light on the middle chest
4) Operation frequency: ≥100 times/ min
5) Ratio of compression and artificial respiratory: 30:2/single or 15:2/double
6) Operation cycle: after 2 valid inflation, then 5 cycles CPR operation according to the ratio of compression and inflation 30:2 or 15:2
