Cardiac arrest & resuscitation
Association Between Capnographic Changes During Pulse Checks of Varying Durations and Clinical Outcomes During Cardiopulmonary Resuscitation: A Multicenter Study From Türkiye (CaPTuRe)
Authors' conclusion
Pulse checks completed within 5 seconds were associated with more favorable capnographic dynamics and higher ROSC rates than those lasting 6-10 seconds. These findings are hypothesis-generating and warrant prospective validation.
Study context
- Population
- Cardiac arrest patients undergoing cardiopulmonary resuscitation (CPR), Türkiyecardiac arrest patients included · Group A 124 · Group B 128
- Participants
- 252 patients
- Comparison
- Pulse checks ≤5 seconds vs >5 to ≤10 seconds
- Group An = 124
- Group Bn = 128reference
Primary result
As reported in the abstract
Capnographic parameters in patients with ROSC vs non-survivors, Group A
- In Group A, patients with return of spontaneous circulation (ROSC) had markedly lower loss rates and shorter recovery times than non-survivors, together with higher pre- and post-CPR ETCO2 values (all p<0.001)
Further findings
| Outcome | Group A | Group B | OR for ROSC (95% CI) | P value | |
|---|---|---|---|---|---|
| Return of spontaneous circulation (ROSC) | 36.3% | 19.5% | 2.39 (1.347–4.242) | P = 0.003 | |
| 0.20.5125OR for ROSC (log scale) |
- Return of spontaneous circulation (ROSC): logistic regression; pulse check duration an independent predictor of ROSC
- Return of spontaneous circulation (ROSC): ROSC rate p=0.005
