西雅图和金县的成功归因于以下高性能CPR的要素:
- Correct hand position
- 每分钟100-120节拍的压缩率
- Depth of compression of 2-2.4 inches (updated to meet American Heart Association 2015 guidelines)
- Full recoil on the upstroke
- 50:50值班周期
- 一秒钟的通风
- Minimal interruptions of CPR(no pause to exceed 10 seconds)
- Intubation and IV start without pausing chest compressions
