Cardiac arrest & resuscitation
Standardisation facilitates reliable interpretation of end-tidal CO2 (ETCO2) during manual cardiopulmonary resuscitation
Authors' conclusion
Standardising ETCO2 eliminates effects of VR and CD variations during manual CPR and facilitates comparison of values and trends among and within patients.
Study context
- Population
- OHCA cases with manual cardiopulmonary resuscitation (CPR)of 1,036 cases
- Participants
- 287 cases
- Exposure
- Standardised ETCO2 vs measured ETCO2
- Outcome
- ETCO2 values and trends during resuscitation
Main finding
As reported in the abstract
Ventilation rate (VR) mostly lower than recommended, highly variable within and among patients
8.8 vpm
Compression depth (CD) mostly within guidelines, less varied
49.8 mm
ETs lower than ETm
7.3 mmHg
Observational data: associations, not effects.
