Want to improve your chances of success in the resus room?  Download a metronome app on your smartphone and set it to a rate of 100-120 beats per minute.  There are a number of cheap (usually free) metronome applications for both iOS and Android devices.
想要提高抢救室复苏成功率吗？在智能手机上应用程序上下载一个节拍器，将它设置为每分钟100-120次的速度。有许多便宜（甚至是免费的）并与iOS和Android设备兼容的节拍器。
A recent review looked at the evidence behind CPR feedback devices and found: 
一个文献回顾对在CPR时应用反馈装置的证据进行了分析，发现：
Compared to baseline, chest compression rates and end-tidal CO2 improved after activation of the metronomes.
与基线相比，在应用节拍器后胸部按压频率和呼气末CO2都有改善。
There was a significant improvement in the hands-off time per minute during CPR
在心肺复苏过程中，每分钟手离开时间有显着的改善。
The proportion of intubation attempts taking under 20 seconds improved
20秒内插管成功比例提高

There were Increased survival rates when implemented in the pre-hospital setting 
在院前就使用时可增加存活率
So go over to the App store and download a free metronome.  Your resus team will be able to stay on track with their compressions and even better - they won't have to hear you sing!
所以，到App店下载一个免费的节拍器。你的复苏团队将能够掌握他们的按压频率- 他们不需要再听你唱歌了！
