Rescuer's work capacity and duration of cardiopulmonary resuscitation

A b s t r a c tBackground: Providing high-quality chest compressions and rescue breaths are key elements in the effectiveness of cardiopulmonary resuscitation. Aim:To investigate the effects of a strength training programme on the quality of prolonged basic cardiopulmonary resuscitation on a manikin. Methods:This was a quasi-experimental trial. Thirty-nine participants with prior basic life support knowledge were randomised to an experimental or control group. They then performed a test of 10 min of chest compressions and mouth-to-mouth ventilation on manikins equipped with a skill reporter tool (baseline or test 1). The experimental group participated in a four-week strength training programme focused on the muscles involved in chest compressions. Both groups were subsequently tested again (test 2).Results: After training, the experimental group significantly increased the mean depth of compression (53.7 ± 2.3 mm vs. 49.9 ± 5.9 mm; p = 0.003) and the correct compression fraction (68.2 ± 21.0% vs. 46.4 ± 29.1%; p = 0.004). Trained subjects maintained chest compression quality over time better than the control group. The mean tidal volume delivered was higher in the experimental than in the control group (701.5 ± 187.0 mL vs. 584.8 ± 113.6 mL; p = 0.040) and above the current resuscitation guidelines. In test 2, the percentage of rescue breaths with excessive volume was higher in the experimental group than in the controls (31.5 ± 19.6% vs. 15.6 ± 13.0%; p = 0.007). Conclusions:A simple strength training programme has a significant impact on the quality of chest compressions and its maintenance over time. Additional training is needed to avoid over-ventilation of potential patients.

“…However, the actual effect on patient outcome is still unknown. Knowing that rescuers’ exhaustion is a limiting factor for CPR performance, 17,19,27,28 it is important to investigate the effects of such devices on rescuers’ physical strain.…”

“…It is difficult to set our findings in context with some prior reports because they recorded different outcome parameters and measured physical strain heterogeneously. While earlier studies used a combination of measures such as heart rate, oxygen consumption, lactate levels, and correct chest compressions, 16,17,19 recently performed studies have introduced scales such as the Borg scale 14,29 …”

“…The overall physical strain due to CPR seems to be well accepted by EMS providers, 13 even if CPR is performed during transportation 14 . Although there is no effect of age on the physiologic response, 15 the level of physical fitness, 16 respective of the rescuers` individual work capacity, 17 may be important to ensure the adequacy of chest compressions. Moreover, it is well known that there is a decrease in the quality of chest compression after the first minute 18,19 …”

“…Rescuer fatigue is a known problem with ACD-CPR, since it takes more energy to do active compression decompression than to do active compression alone 79,82 . Back fatigue is definitely reduced if the rescuer either kneels beside the thorax of the victim or works astride the victim on his or her knees.…”
