"PQRST" - Capnography in Cardiac Arrest
“PQRST”--心脏骤停时的二氧化碳检测仪的应用
1 Resuscitation of the patient in cardiac arrest can be stressful, chaotic, and variable depending on the setting.
2 心脏骤停的复苏过程可能是紧张的、混乱，和因病情而变化。
3 Capnography is a valuable tool in the management of patients in cardiac arrest.
4 二氧化碳检测仪是抢救心脏骤停患者的重要工具。
5 Heradstveit, et al. published a mnemonic for the use of capnography during cardiac arrest:
6 Heradstveit等发表了一篇文章，提出了一个帮助记忆心脏骤停时应用二氧化碳监测仪的要点。
P - Position of the tube
P – 气管导管的位置
The sensivity and specificity of capnography for endotracheal tube confirmation is superior to auscultation and capnometry.
二氧化碳监测仪对判断气管导管的位置的灵敏性和特异性优于听诊和二氧化碳变色器。
Q - Quality of CPR
Q – CPR的质量
Early detection of poor-quality compressions.
早期发现低质量的按压
R - ROSC
R -自主循环恢复(Return of spontaneous circulation，ROSC)
A sudden increase in end-tidal CO2 can indicate ROSC without interrupting CPR for pulse checks.
呼气末二氧化碳的突然增多预示着自主循环的恢复，不需要中断CPR检查脉搏
S - Strategy
S – 策略
May assist clinicians in determining underlying etiology of cardiac arrest.
可以帮助临床医生确定心脏骤停的根本原因。
T - Termination
T – 结束
An end-tidal CO2 value < 10 mm Hg after 20 min of resuscitation has been shown to be very accurate in
在复苏20分钟后呼气末二氧化碳的值< 10 mm Hg ，已经可以准确无误的预示死亡predicting death.
