“…High-quality CPR in infants, [15,16] as well as in adults, [17,18] can be a challenge even for certified CPR providers. A constant quality assurance system, including repetitive practical training, is necessary, and the quality of chest compressions is influenced by motor skills and the working environment.…”

Background:Providing adequate chest compression is essential during infant cardio-pulmonary-resuscitation (CPR) but was reported to be performed poor. The “new 2-thumb technique” (nTTT), which consists in using 2 thumbs directed at the angle of 90° to the chest while closing the fingers of both hands in a fist, was recently introduced. Therefore, the aim of this study was to compare 3 chest compression techniques, namely, the 2-finger-technique (TFT), the 2-thumb-technique (TTHT), and the nTTT in an randomized infant-CPR manikin setting.Methods:A total of 73 paramedics with at least 1 year of clinical experience performed 3 CPR settings with a chest compression:ventilation ratio of 15:2, according to current guidelines. Chest compression was performed with 1 out of the 3 chest compression techniques in a randomized sequence. Chest compression rate and depth, chest decompression, and adequate ventilation after chest compression served as outcome parameters.Results:The chest compression depth was 29 (IQR, 28–29) mm in the TFT group, 42 (40–43) mm in the TTHT group, and 40 (39–40) mm in the nTTT group (TFT vs TTHT, P < 0.001; TFT vs nTTT, P < 0.001; TTHT vs nTTT, P < 0.01). The median compression rate with TFT, TTHT, and nTTT varied and amounted to 136 (IQR, 133–144) min–1 versus 117 (115–121) min–1 versus 111 (109–113) min–1. There was a statistically significant difference in the compression rate between TFT and TTHT (P < 0.001), TFT and nTTT (P < 0.001), as well as TTHT and nTTT (P < 0.001). Incorrect decompressions after CC were significantly increased in the TTHT group compared with the TFT (P < 0.001) and the nTTT (P < 0.001) group.Conclusions:The nTTT provides adequate chest compression depth and rate and was associated with adequate chest decompression and possibility to adequately ventilate the infant manikin. Further clinical studies are necessary to confirm these initial findings.

“…The quality of chest compressions (CC) performed by laypersons and staff with duty to assist is a decisive factor in the success of CPR [3]. However, some studies demonstrate that the quality of CPR performance during SCA is poor, even when CPR is conducted by medical staff [4][5][6][7]. Due to the fact that CC must be performed as continuously as possible and maintained over time, fatigue may be also a critical quality factor in CC [8][9][10].…”

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.

“…These feedback devices provide visual and/or auditory feedback based on quantitative CPR metrics and have been reported to improve the quality of CPR [8,9]. Furthermore, real-time feedback devices have been proven to improve CPR skill acquisition and retention, and enhance quality of chest compression, even if used by inexperienced providers [10][11][12][13]. Therefore, use of real-time feedback devices might be particularly advantageous, especially if used by low to moderately experienced CPR providers, including lifeguards.…”

A b s t r a c tBackground: Drowning is a common issue at many pools and beaches, and in seas all over the world. Lifeguards often act as bystanders, and therefore adequate training in high-quality cardiopulmonary resuscitation (CPR) and use of adequate equipment by lifeguards is essential. Aim:The aim of this study was to evaluate the impact of the recently introduced CPRMeter (Laerdal, Stavanger, Norway) on quality of CPR, if used by moderately experienced CPR providers. In particular, we tested the hypothesis that using the CPRMeter improves quality of chest compression by lifeguards compared to standard non-feedback CPR. Methods:The study was designed as prospective, randomised, cross-over manikin trial. Fifty lifeguards of the Volunteer Water Rescue Service (WOPR), a Polish nationwide association specialised in water rescue, participated in this study. Participants were randomly assigned 1:1 to one of two groups: a feedback group and a non-feedback group. Participants swim a distance of 25 m in the pool, and then they were asked to haul a manikin for the second 25 m, simulating rescuing a drowning victim. Once participants finished the second 25-m distance, participants were asked to initiate 2-min basic life support according to the randomisation. Results:The median quality of CPR score for the 2-min CPR session without feedback was 69 (33-77) compared to 84 (55-93) in the feedback group (p < 0.001). Compression score, mean depth, rate of adequate chest compressions/min, and overall mean rate during the CPR session improved significantly in the feedback group, compared to the non-feedback group. Conclusions:Using the visual real-time feedback device significantly improved quality of CPR in our relatively unexperienced CPR providers. Better quality of bystander CPR is essential for clinical outcomes, and therefore feedback devices should be considered. Further clinical studies are needed to assess the effect of real-time visual devices, especially in bystander-CPR.
