BACKGROUND: During @entity1167 , end-tidal @entity544 (ETCO2) monitoring is recommended as a chest compression performance indicator. However, its frequency of use during out-of-hospital @entity1167 (OHCA) and its benefits have never been evaluated in real clinical situations. OBJECTIVE: We investigated OHCA @entity1 in Taiwan to evaluate the frequency of ETCO2 monitoring and its effects on sustained return of spontaneous circulation (ROSC). METHODS: We sampled the Taiwan National Health Insurance claims database, which contains 1 million beneficiaries. All adult beneficiaries older than 18  years who presented with OHCA and received chest compression between 1 January 2005 and 31 December 2012 were enrolled. We further identified @entity1 with ETCO2 monitoring and matched each 1 with 20 @entity1 who did not receive ETCO2 monitoring based on their propensity scores. A simple conditional logistic regression model was applied to compare the odds ratio (OR) for sustained ROSC in the matched cohorts. RESULTS: A total of 5041 OHCA @entity1 were enrolled. The frequency of ETCO2 monitoring has increased since 2010 but still is low. After matching, 53 @entity1 with ETCO2 monitoring and 1060 without ETCO2 monitoring were selected. The OR of sustained ROSC in the ETCO2 group was significantly increased (2.38, 95  % CI 1.28-4.42). CONCLUSION: @entity1 who received ETCO2 monitoring during OHCA had a higher possibility of sustained ROSC, but the overall use of ETCO2 monitoring is still low despite strong recommendations for its use.

End-tidal XXXX monitoring may be associated with a higher possibility of return of spontaneous circulation during out-of-hospital @entity1167 : a population-based study.
