The success of Seattle and King County can be attributed to the following elements of high-performance CPR:
- 正确的手位置
- Compression rate of 100-120 beats per minute
- 压缩深度为2-2.4英寸(已更新以满足美国心脏协会2015指南)
- 上风的完全后坐力
- 50:50 duty cycles
- Ventilations of one second each
- CPR的最小中断(没有停顿超过10秒)
- 插管和IV开始而不会停止胸部压缩
- 除颤期间悬停在胸部。5
Each of these elements have been implemented system-wide and reinforced throughout the years.
