“…During CPR practise, triceps brachii plays an important role in extending the elbow [ 17 ], whereas rectus abdominis controls the trunk and stabilizes the upper body to provide a proper force distribution during chest compressions [ 6 ]. For this reason, contractile properties of these muscles were measured through non-invasive and non-demanding TMG in this study.…”

ObjectiveTo analyse the acute muscular fatigue (AMF) in triceps brachii and rectus abdominis during compression-only and standard cardiopulmonary resuscitation (CPR) performed by certified basic life support providers.MethodsTwenty-six subjects were initially recruited and randomly allocated to two study groups according to the muscles analysed; eighteen finally met the inclusion criteria (nine in each group). Both groups carried out two CPR tests (compression-only and standard CPR) of 10 min divided into five 2-min intermittent periods. The ventilation method was freely chosen by each participant (mouth-to-mouth, pocket-mask or bag-valve-mask). CPR feedback was provided all the time. AMF was measured by tensiomyography at baseline and after each 2-min period of the CPR test, in triceps brachii or rectus abdominis according to the study group.ResultsRectus abdominis’ contraction time increased significantly during the fifth CPR period (p = 0.020). Triceps brachii’s radial muscle belly displacement (p = 0.047) and contraction velocity (p = 0.018) were lower during compression-only CPR than during standard CPR. Participants who had trained previously with feedback devices achieved better CPR quality results in both protocols. Half of participants chose bag-valve-mask to perform ventilations but attained lower significant ventilation quality than the other subjects.ConclusionsCompression-only CPR induces higher AMF than standard CPR. Significantly higher fatigue levels were found during the fifth CPR test period, regardless of the method. Adequate rescuer’s strength seems to be a requisite to take advantage of CPR quality feedback devices. Training should put more emphasis on the quality of ventilation during CPR.

“…In 2013 in Japan, Yasuda et al 9 conducted a study to illustrate the different muscles used when performing chest compressions while kneeling on the floor and standing in a moving ambulance. They concluded that the low quality of chest compressions in ambulance may be attributed to an alteration of the technique of performing chest compressions.…”

“…Heart rate (HR) was measured at rest, during chest compression, and during recovery using a Life Scope 8 (Nihon Kohden Co., Tokyo, Japan). During chest compressions, the surface EMG collected data from the triceps brachii, deltoid, trapezius, erector spinae, external oblique muscle, rectus femoris, biceps femoris, and medial gastrocnemius muscles using SX230‐1000 electrodes (Biometrics Ltd., UK) (Trowbridge et al, ; Yasuda et al, ). The electrodes were attached to the belly of each muscle, and the skin was abraded and cleaned with alcohol before attachment to minimize impedance.…”

Aim Cardiopulmonary resuscitation is vital for survival after cardiac arrest, and chest compressions are an important aspect of this. When performing chest compression in a hospital setting, the rescuer often has to kneel on the bed to overcome inconvenient differences in height between the rescuer and the bed. However, as yet no study has evaluated the quality of chest compressions in this position. The aim of this study was to examine the impact on the quality of chest compressions while kneeling on the bed. Methods Fifteen female students performed 2‐min chest compressions on a manikin placed on the floor and a bed. Measurement parameters included compression depth, heart rate, integrated electromyogram, and a visual analog scale. The parameters were measured every 30 s and were statistically compared between the conditions. Results Compression depth at 30, 60, 90, and 120 s differed significantly between the conditions. Heart rate values at 150 and 210 s of recovery significantly differed between the conditions. Integrated electromyogram values for the trapezius, rectus femoris, and biceps femoris differed between the floor and bed conditions during 2‐min chest compressions, whereas the external oblique muscle significantly differed at 60 and 120 s. Visual analog scales for fatigue, effectiveness, and stability significantly differed between the conditions. Conclusion Kneeling on the bed does not enable grounding of the toe, causing the upper body to be unstable and limiting generation of the power required for chest compression. Our results suggest that rotation every minute is necessary to maintain effective cardiopulmonary resuscitation while kneeling on the bed.
