Features:
1. Simulate standard open airway 
2. External breast compression: display device and alarm device
1) Indicator light display of correct and wrong compression; alarm of wrong compression;
2) Intensity display of correct (at least 5cm) and wrong (less than 5cm) compression; alarm of wrong compression. Digital strip indicator light (yellow, green, red) shows compression depth;
3. Artificial respiration (Inhalation): display device and alarm device
1) Display of inhalation (≤500ml-600ml≤), strip indicator light shows inhalation volume; alarm of wrong operation
2) Inhalation too quickly or too much result in air entering into stomach; indicator light display and alarm prompting.
4. Ratio of compression and artificial respiration: 30:2 (one or two person)
5. Operating cycle: 2times correct respiration, one cycle includes five times of 30:2 (one or two person)
6. Operation frequency: at least 100 times per minute 
7. Operation methods: exercise operation
8. Examination of pupil response: mydriasis and myosis
9. Examination of carotid response: pinch the pressure ball by hand and simulate carotid pulse
10. Working conditions: Input power is 110-240V
