"PQRST" - Capnography in Cardiac Arrest
“PQRST”--心臟驟停時的二氧化碳檢測儀的應用
1 Resuscitation of the patient in cardiac arrest can be stressful, chaotic, and variable depending on the setting.
2 心臟驟停的復蘇過程可能是緊張的、混亂，和因病情而變化。
3 Capnography is a valuable tool in the management of patients in cardiac arrest.
4 二氧化碳檢測儀是搶救心臟驟停患者的重要工具。
5 Heradstveit, et al. published a mnemonic for the use of capnography during cardiac arrest:
6 Heradstveit等發表了一篇文章，提出了一個幫助記憶心臟驟停時應用二氧化碳監測儀的要點。
P - Position of the tube
P – 氣管導管的位置
The sensivity and specificity of capnography for endotracheal tube confirmation is superior to auscultation and capnometry.
二氧化碳監測儀對判斷氣管導管的位置的靈敏性和特異性優于聽診和二氧化碳變色器。
Q - Quality of CPR
Q – CPR的質量
Early detection of poor-quality compressions.
早期發現低質量的按壓
R - ROSC
R -自主循環恢復(Return of spontaneous circulation，ROSC)
A sudden increase in end-tidal CO2 can indicate ROSC without interrupting CPR for pulse checks.
呼氣末二氧化碳的突然增多預示著自主循環的恢復，不需要中斷CPR檢查脈搏
S - Strategy
S – 策略
May assist clinicians in determining underlying etiology of cardiac arrest.
可以幫助臨床醫生確定心臟驟停的根本原因。
T - Termination
T – 結束
An end-tidal CO2 value < 10 mm Hg after 20 min of resuscitation has been shown to be very accurate in
在復蘇20分鐘后呼氣末二氧化碳的值< 10 mm Hg ，已經可以準確無誤的預示死亡predicting death.
