Background: Effective chest compression (CC) is vital in cardiopulmonary resuscitation (CPR), and rescuer’s fatigue negatively affects quality of CPR. However, there is no consensus on the appropriate number of personnel needed for CC to avoid rescuer’s fatigue. Objective: We determined the appropriate number of personnel needed for 30-min CPR in a rescue-team in a hospital. Methods: We conducted a preliminary randomized, crossover, manikin trial on healthcare providers. We divided them into Groups A to D according to the intervals between the 2-min CC and assigned a different interval to each group. Groups A, B, C, and D performed CCs at 2-, 4-, 6-, and 8-min intervals as in 2, 3, 4, and 5 personnel, respectively. All participants performed CCs for 30 min with different intervals depending on the assigned group; participants allocated to Groups A, B, C, and D performed 8, 5, 4, and 3 cycles, respectively. We compared the differences between first cycle and the second to the last cycle Results: We enrolled 42 participants (age: 25.2±4.2, men 47.6%) for the preliminary evaluation. We used Kruskal-Wallis for the analysis. Participants in the less interval Groups A and B performed faster (A: -24.28±15.18, B: -7.90±13.49, C: -11.27±17.01, D: -2.38±3.31, P=0.03) and shallower CCs (A: -4.42±6.92, B: -3.18±5.43, C: -0.18±5.74, D: -1.23±4.10, P=0.62). Women-rescuers performed faster (A: -27.25±12.23, B: -7.00±13.97, C: -8.16±19.26, D: 3.16±4.66, P= 0.05) and shallower CCs (A: -6.25±7.54, B: -3.00±6.89, C: -3.66±3.32, D: -0.16±4.35, P=0.58). However, CCs of men-rescuers were not faster (A: -20.33±20.65, B: -9.00±14.44, C: -15.00±15.11, D: -7.14±16.70, P= 0.60) or shallower (A: -2.00±6.55 B: -3.40±3.78, C: 4.00±5.33, D: -2.14±3.98, P=0.06). Conclusion: At least four rescuers (Group C) may be needed to reduce rescuer’s fatigue for 30-min CPR. If the team only includes women, more personnel would be needed as women experience fatigue faster.

Introduction: Although quality of cardiopulmonary resuscitation (CPR) is a key to increase survival after out-of-hospital cardiac arrest (OHCA), little is known about the quality of bystander CPR and its association with survival outcomes after OHCA. Objective: To evaluate the association of quality of bystander CPR and patient outcomes after OHCA. Methods: Designs: Population-based cohort study. Cases: All OHCA cases treated by emergency medical services (EMS) personnel in Toyonaka city between September 2011 and August 2013. Data collection and analyses: EMS personnel assessed bystanders’ CPR quality including hand position, depth, and tempo of chest compressions using a specific data form at the scene. Fleiss’ Kappa statistics was used to assess the evaluation reliability among EMS personnel and the Kappa value was 0.81 before the study. The primary outcome was patient one-month survival with favorable neurological outcome and it was compared between the good-quality CPR group and the poor-quality CPR group. Results: Among 877 cases, bystander CPR was attempted in 429 (48.9%). Data on quality of CPR was applicable in 272 (63.4%) of them. In the good-quality CPR group, bystanders were younger, more likely to be health care provider, and have experience of CPR training than in the poor-quality of CPR group. The proportion of patients with neurologically favorable one-month survival was somewhat greater in the good-quality of CPR group (4.6% versus 3.0%), although it was statistically insignificant. Conclusions: Better quality of bystander chest compressions might increase OHCA patient survival. Further efforts to improve quality of CPR by general public are needed.

Abstract Background: Out-of-hospital cardiac arrest (OHCA) is a life-threatening condition with an overall survival rate that generally does not exceed 10%. Several factors play essential roles in increasing survival among patients experiencing cardiac arrest outside the hospital. Previous studies have reported that implementing a dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) program increases bystander CPR, quality of chest compressions, and patient survival. This study aimed to assess the effectiveness of a DA-CPR program developed by the Thailand National Institute for Emergency Medicine (NIEMS). Methods: This was an experimental study using a manikin model. The participants comprised both health care providers and non-health care providers aged 18 to 60 years. They were randomly assigned to either the DA-CPR group or the uninstructed CPR (U-CPR) group and performed chest compressions on a manikin model for two minutes. The sequentially numbered, opaque, sealed envelope method was used for randomization in blocks of four with a ratio of 1:1. Results: There were 100 participants in this study (49 in the DA-CPR group and 51 in the U-CPR group). Time to initiate chest compressions was statistically significantly longer in the DA-CPR group than in the U-CPR group (85.82 [SD = 32.54] seconds versus 23.94 [SD = 16.70] seconds; P <.001). However, the CPR instruction did not translate into better performance or quality of chest compressions for the overall sample or for health care or non-health care providers. Conclusion: Those in the CPR-trained group applied chest compressions (initiated CPR) more quickly than those who initiated CPR based upon dispatch-based CPR instructions.

Background To compare the 2‐finger and 2‐thumb chest compression techniques on infant manikins in an out‐of‐hospital setting regarding efficiency of compressions, ventilation, and rescuer pain and fatigue. Methods and Results In a randomized crossover design, 78 medical students performed 2 minutes of cardiopulmonary resuscitation with mouth‐to‐nose ventilation at a 30:2 rate on a Resusci Baby QCPR infant manikin (Laerdal, Stavanger, Norway), using a barrier device and the 2‐finger and 2‐thumb compression techniques. Frequency and depth of chest compressions, proper hand position, complete chest recoil at each compression, hands‐off time, tidal volume, and number of ventilations were evaluated through manikin‐embedded SkillReporting software. After the interventions, standard Likert questionnaires and analog scales for pain and fatigue were applied. The variables were compared by a paired t ‐test or Wilcoxon test as suitable. Seventy‐eight students participated in the study and performed 156 complete interventions. The 2‐thumb technique resulted in a greater depth of chest compressions (42 versus 39.7 mm; P <0.01), and a higher percentage of chest compressions with adequate depth (89.5% versus 77%; P <0.01). There were no differences in ventilatory parameters or hands‐off time between techniques. Pain and fatigue scores were higher for the 2‐finger technique (5.2 versus 1.8 and 3.8 versus 2.6, respectively; P <0.01). Conclusions In a simulation of out‐of‐hospital, single‐rescuer infant cardiopulmonary resuscitation, the 2‐thumb technique achieves better quality of chest compressions without interfering with ventilation and causes less rescuer pain and fatigue.
