“…During sustained CCR blood lactate concentrations and heart rate increased significantly over time, and with comparable magnitude as reported in previous studies [7,20,21]. These markers of exercise intensity, as well as the appearance of shallow chest compressions, are repeatedly recorded concurrently after 1 min of sustained CCR [7,21,22].…”

“…These markers of exercise intensity, as well as the appearance of shallow chest compressions, are repeatedly recorded concurrently after 1 min of sustained CCR [7,21,22]. Noticeably, we were unable to predict changes in heart rate and blood lactate concentrations through participants' characteristics, cardiopulmonary exercise capacity and muscle strength.…”

Objective Sustained external chest compressions during cardiocerebral resuscitation (CCR) are physically demanding. It might be hypothesized that a high cardiopulmonary exercise capacity and/or muscle strength delays the development of physical fatigue and, consequently, preserves CCR quality. We intended to assess the impact of cardiopulmonary exercise capacity and muscle strength on CCR quality.Methods Fifteen healthcare professionals (10 men and five women, mean age 34 ± 9 years) performed a 15-min hands-on CCR session on an adult training manikin. CCR compression depth (from which CCR quality was calculated) and frequency were monitored. During CCR we assessed serial blood lactate concentrations, and provided continuous heart rate monitoring. Relationships were examined between participant characteristics, peak cardiopulmonary exercise capacity, ventilatory threshold, maximal muscle strength, muscle strength endurance and CCR quality.Results Significant univariate correlations were found between 15-min CCR quality and body height (r = 0.53), ventilatory threshold (r = 0.67), peak oxygen uptake capacity (r = 0.54), peak cycling power output (r = 0.54), and maximal isometric elbow extension strength (r = 0.55) (P < 0.05). CCR quality was significantly lower in females, when compared with males (P < 0.05). Within different timeframes, CCR quality was mainly related to the ventilatory threshold up to the first 5 min (P < 0.05), whereas CCR quality was mainly related to maximal isometric elbow extension strength after 5 min (P < 0.05).Conclusion In healthcare professionals, the ventilatory threshold is significantly related to CCR quality during the first few min. Healthcare professionals who are regularly involved in CCR should therefore aim to achieve/sustain a high aerobic exercise capacity.

“…One simulation study (LOE 5) 210 of six physicians (aged 25-40 years) and another study (LOE 5) 211 of 10 healthy medical students showed that performing chest compressions increased rescuer oxygen consumption. The authors considered that this increase in oxygen consumption was sufficient to cause myocardial ischaemia in individuals with coronary heart disease.…”

“…Some old studies report cardiocirculatory data of the ''rescuers'' in CRP trainings, e.g., a heart rate of 115/min (Lonergan et al 1981). But the conditions of the experiments were insufficiently described, e.g., there is no information given about the frequency of CC or the depth of the compressions (Lonergan et al 1981). Up to now, there are no data available which describe the workload during CPR in relation to a baseline workload measure to determine whether an individual is able to perform CPR safely or not.…”

CPR can be performed by healthy people within the range of aerobic endurance. The minimal requirements for trainings are 1.6-1.8 W/kg body weight in standard cycling ergometry. People at risk should be trained very careful. Since there is no significant lower workload when following the 1995 recommendations, people at risk should be trained according to the latest recommendations. In the case of a real resuscitation, such trained individuals must additionally take into account any symptoms.
