Effect of rescuer heart rate changes on the quality of infant CPR: a simulation-based study.
Trial report in BMC medical education, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study aimed to evaluate whether increases in heart rate-used as an objective surrogate marker of rescuer fatigue-could influence CPR performance during infant chest compressions.
methodsThis study was a manikin-based simulation study that enrolled PALS-certified pediatric emergency nurses matched by clinical experience and randomly assigned to three groups. All participants performed three 2-min cycles of infant chest compressions on a manikin (Little Baby QCPR). Each group completed a 90-s exercise protocol at different time points to induce varying degrees of heart-rate elevation. The primary outcome was the difference in CPR quality across groups according to heart-rate variation (percentage increase from baseline).
resultsTwenty-seven nurses were enrolled and evenly allocated to Groups A, B, and C (n = 9 each). Heart rate increased immediately after exercise in all groups and gradually declined during subsequent compression cycles, with no significant between-group differences at any time point (baseline 85-100 bpm/cycle, peak 130-150 bpm/cycle). Across all cycles, CPR performance metrics-including total compression count, hand-placement accuracy, mean compression velocity, compression depth, and chest recoil-showed no significant within-group changes for any group. Similarly, no significant between-group differences were observed for any CPR parameter during any cycle. In post-hoc analyses, stratification by the median percentage increase in heart rate (> 67.7% vs. < 67.7%) revealed no statistically significant differences in CPR quality between groups.
conclusionWithin this short, three-cycle simulation, exercise-induced heart-rate elevation was not associated with measurable deterioration in infant CPR quality.
