Abrupt rise of end tidal carbon dioxide level was a specific but non sensitive marker of return of spontaneous circulation in patient with out-of-hospital cardiac arrest. ↑ Grmec, S, et al.Utstein style analysis of out-of-hospital cardiac arrest-bystander CPR and end expired carbon dioxide.Capnography during cardiopulmonary resuscitation: Current evidence and future directions. The effectiveness of out-of-hospital use of continuous end-tidal carbon dioxide monitoring on the rate of unrecognized misplaced intubation within a regional emergency medical services system. ETCO2>24.5 mmHg has sensitivity of 90%, ETCO2ETCO2>35 mmHg has a sensitivity 100%, ETCO2250.ETCO2 monitoring detects clinically signifcant respiratory events before SPO2 or clinically noted apnea/hypoventilation.Capnography will show real-time respiratory changes and apnea.ETCO2 level of 10mmHg or less after 20 min of CPR predicts death.Loss of ROSC can be determined by a significant drop signifies drop in ETCO2.CPR does not have to be stopped for pulse checks.20mHg has a sensitivity of 20% and a specificity of 99% for ROSC.10mHg has a sensitivity of 33% and a specificity of 97% for ROSC.Attaining ROSC is associated with an ETCO2 jump 10mmHg with ROSC (13.5 on average).ETCO2 10-20mmHg signifies high quality chest compressions.In out of hospital use, this had SN 1.0 and SP 1.0 in detected good placement Ĭardiac Arrest Monitoring Ensure adequate chest compressions.Assess for ETT placement using presents of measurable ETCO2 and waveform.The curve peaks at the end of Phase III which is noted as the End-Tidal CO2 measurement.This is followed by a more gradual increase in CO2 (Phase III).Then a rapid rise in CO2 rich air is noted (Phase II). ![]()
