Abstract

Background: The performance of quality chest compressions according to the international guidelines affects the outcomes and survival in cardiac arrest. Objectives: To analyze the influence of fatigue and physical fitness on the rescuer's performance during a period of 6 minutes of continuous chest compressions. Methodology: Descriptive-correlational study, with a sample of 38 professionals experienced in resuscitation. Fatigue was assessed through capillary blood lactate levels; physical fitness through strength tests and body composition; and the rescuer's performance through the percentage of correct compressions per minute, which were performed in manikin. Results: The percentage of correct compressions decreased every minute (p<.05). The lactate levels increased from a baseline value of 1.7±.7mmol/L to 5.4±1.5mmol/L, and remained high after 20 minutes of rest. Grip strength, and muscle strength and mass of the trunk and upper limbs were positively correlated with the percentage of correct chest compressions. Conclusion: The body mass index and the physical fitness components - muscle strength and mass - were the variables that best explained the quality of the heart massage over time.
