Influence of environmental temperature on chest compression quality and rescuer physiological responses.
Article in Journal of occupational health, 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
objectivesPerforming chest compressions in high-temperature environments may increase the physiological strain on rescuers, potentially affecting the quality of cardiopulmonary resuscitation (CPR). This study aimed to examine the effects of environmental temperature on physiological responses, perceived exertion, and chest compression performance.
methodsTwenty male participants performed 10 minutes of chest compressions under 2 temperature conditions: 35°C (HOT) and 25°C (CON). Physiological parameters, including rectal temperature (Tre), skin temperature, heart rate (HR), and rating of perceived exertion (RPE), were measured. The number of successful chest compressions was also recorded.
resultsThe results indicated no significant differences in Tre, heart rate, or RPE during chest compressions between HOT and CON. However, Tre showed a tendency to increase continuously during the recovery phase at 35°C. HR decreased during recovery in both conditions but remained elevated at 35°C compared with resting levels. A significant interaction effect was observed in mean skin temperature, suggesting different thermoregulatory responses between HOT and CON.
conclusionsThese findings suggest that although subjective exertion and cardiovascular responses may not differ significantly, prolonged exposure to high temperatures could influence thermoregulation in rescuers. Future research should explore the long-term impact of heat stress on CPR performance and rescuer safety.
