Cardiac arrest & resuscitation
Filtered electrocardiogram combined with end-tidal carbon dioxide for the identification of patients’ cardiac arrest status during uninterrupted chest compressions in cardiopulmonary resuscitation
Authors' conclusion
Our findings suggest that the fEEt strategy might potentially help clinicians identify real time cardiac arrest status during ongoing chest compressions.
Study context
- Population
- Cardiac arrest patients during cardiopulmonary resuscitation at a tertiary hospital in China575 segments analysed
- Participants
- 51 patients
- Comparison
- fEEt strategy vs traditional assessment
- Outcome
- Consistency and accuracy of fEEt-classified cardiac arrest status (ROSC, shockable rhythm, PEA, asystole) vs traditional assessment

Performance
As reported in the abstract
Agreement with traditional assessment
| Test or model | Kappa, return of spontaneous circulation (ROSC) | Kappa, shockable rhythm | Kappa, pulseless electric activity (PEA) | Kappa, asystole |
|---|---|---|---|---|
| fEEt | 0.695 | 0.704 | 0.535 | 0.574 |
fEEt
Kappa, return of spontaneous circulation (ROSC)0.695
Kappa, shockable rhythm0.704
Kappa, pulseless electric activity (PEA)0.535
Kappa, asystole0.574
- Good consistency for ROSC and shockable rhythm
- P < 0.001
- Moderate consistency for PEA and asystole
- P < 0.001
Further findings
| Outcome | fEEt |
|---|---|
| Decision to stop chest compressions (ROSC/shockable = cessation; PEA/asystole = continue) | |
| Kappa | 0.656 |
- Decision to stop chest compressions (ROSC/shockable = cessation; PEA/asystole = continue) — Good consistency with traditional assessments
- p < 0.001
