Acute cardiac care & 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

Primary result
As reported in the abstract
Capnographic parameters in 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
