1. Pupil response: Bilateral pupils contrast observation.
2. Carotid artery response: pinching pressure the ball to simulate carotid pulse;
3. Chest compressions;
4. Standard airway open;
5. Feasible three ways to open the airway: lift jaw with head back, lift the head and neck, lift jaw by hands;
6. Mouth resuscitation and ventilator-assisted breathing, effective artificial respiration has visible chest rise;
7. Simulate larygeal mask airway and composite cannula can be inserted into the airway;
8. Verify endotracheal intubation is correct ot not: a catheter inserted into the trachea, lungs will swell (plastic bladder) when inflated; If the catheter is inserted by mistake esophagus, stomach will swell when inflated (plastic pouch). Observed pulmonary respiration;
9. Artificial ventilation;
10. Oral or nasal intubation and esophageal intubation;
11. Open the airway and practise from resuscitator bag to breathing mask or from resuscitator bag to the cannula;
12. Respiratory tract is simple and can be replaced;
13. Easy to carry, suitable for field training.
