Cardiac arrest (non-traumatic out-of-hospital cardiac arrest, with absolute contraindications for external chest compression)
Conditions
Interventions
Experimental group:Using the CPR-LW1000 abdominal compression and chest compression resuscitation device, fix the suction cup at the midline of the abdomen between the xiphoid process and the umbilicu
the compression force should be 20-30 kg, the pressure force 40-50 kg, the compression-to-ventilation ratio 1:1, and the compression-to-ventilation ratio 30:2. At the same time, follow the 2010 AHA Ad
