Aim of the Study: The aim was to compare cardiopulmonary resuscitation (CPR) quality of an automated external defibrillator (AED) with and without additional video instruction during basic life support (BLS) by laypersons.Methods: First-year medical students were randomized either to an AED with audio only or audio with additional video instructions during CPR. Each student performed 4 min of single-rescuer chest compression only BLS on a manikin (Ambu Man C, Ballerup, Denmark) using the AED. The primary outcome was the effective compression ratio during this scenario. This combined parameter was used to evaluate the quality of chest compressions by multiplying compressions with correct depth, correct hand position, and complete decompression by flow time. Secondary outcomes were percentages of incomplete decompression and hand position, mean compression rate, time-related parameters, and subjective assessments.Results: Effective compression ratio did not differ between study groups in the overall sample (p = 0.337) or in students with (p = 0.953) or without AED experience (p = 0.278). Additional video instruction led to a higher percentage of incorrect decompressions (p = 0.014). No significant differences could be detected in time-related resuscitation parameters. An additional video was subjectively rated as more supporting (p = 0.001).Conclusions: Audio–video instructions did not significantly improve resuscitation quality in these laypersons despite that it was felt more supportive. An additional video to the verbal AED prompts might lead to cognitive overload. Therefore, future studies might target the influence of the video content and the potential benefits of video instructions in specific populations.

ObjectivesThis study assessed the feasibility and preliminary efficacy of a 2-hour compression-only cardiopulmonary resuscitation and automated external defibrillator (CO-CPRAED) course in secondary school students.DesignProspective pre-post feasibility study.Setting and participants128 students (12–15 years old) without prior basic life support (BLS) training at four secondary schools in Hong Kong. All students were followed up at 3 months after training.InterventionsEmergency medicine-trained nurse and physicians taught the 2-hour CO-CPRAED course using the American Heart Association ‘CPR in School Training Kit’ programme. Students were trained in groups up to 40 students/session, with an instructor to student ratio not exceeding 1:10. To practise hands-on compressions, the manikin to student ratio was 1:1. For a simulated cardiac arrest, the manikin and AED to student ratio was 1:10.Primary and secondary outcomesCPR and AED knowledge, attitude statements towards bystander CPR and AED, quality of BLS performance skills during training and at 3 months.ResultsSome students (46%) knew how deep to push on an adult chest when doing CO-CPR before training. The course was associated with an increase in knowledge score (pretraining 55%, post-training 93%; adjusted mean difference (MD) 38%, 95% CI 33% to 43%; p<0.001). Most students (68%) thought that CPR education in senior secondary school was essential before training. The students had a very positive attitude towards CPR; no change in the mean (SD) attitude score out of 30 over time (pretraining 27.2 (2.5), post-training 27.6 (2.7); adjusted MD 0.5, 95% CI −0.1 to 1.0; p=0.132). Most students were competent in performing BLS immediately after training (77%) and at 3 months (83%) (adjusted MD 6%, 95% CI −4% to 15%; p=0.268).ConclusionsThe results demonstrate the feasibility of scaling up the number of secondary schools trained in a brief CO-CPRAED course within the local school curriculum.

Background: Public access defibrillation (PAD) with automated external defibrillator (AED) is a widely available and beneficial intervention for cardiac arrest. The quality of chest compressions (CC) is an important determinant of the outcome of cardiopulmonary resuscitation (CPR). In Japan, AED with real-time audiovisual feedback is being implemented, and has been available to bystanders since 2011. However, the benefit of CC feedback systems for laypersons remains unclear. In this study, we sought to determine the effects of audiovisual feedback system on the quality of CC in bystanders with different medical backgrounds. Methods: A total of 478 individuals (151 healthcare professionals [mean age, 31.3 years], 76 medical students [mean age, 23.6 years], and 251 non-healthcare professionals [mean age, 40.1 years]) participated in a CPR quality improvement challenge. Participants performed two 2-min trials of CC on a training manikin equipped with an accelerometer-based system for measuring both rate and depth of CC. Real-time audiovisual feedback was disabled during first trial, but activated during the second trial. The quality of CC was evaluated by counting the number of compressions with the appropriate depth (5.0-10 cm) and rate (100-120 cpm) in each trial. Results: Among all participants, mean depth of CC was higher (6.35 vs. 5.87 cm), and mean rate was lower (102.4 vs. 112.2 cpm) when the feedback system was activated than when it was disabled (p < 0.05). When real-time feedback was activated, non-healthcare professional participants performed CC of greater depth (6.41 vs. 5.63 cm) than healthcare professionals (6.25 vs. 6.09 cm) and medical students (6.34 vs. 6.19 cm) (p < 0.05). The quality index of CC, which the percentage of adequate depth and rate, was also significantly improved regardless medical backgrounds (p < 0.05). Conclusions: The use of real-time CPR feedback systems improves the quality of CC performed by individuals of all backgrounds, especially non-healthcare personnel. PAD with AED providing CPR feedback technologies may elevate the survival rate of out-of-hospital cardiac arrest and increase the likelihood of favorable outcomes.

Introduction The aim of this study was to determine the effect of hand positioning on the quality of external chest compression (ECC) by novice rescuers. Methods This observational simulation study was conducted for 117 included participants. After completion of an adult cardiopulmonary resuscitation (CPR) training program for 3-h, the participants selected which of their hands would be in contact with the mannequin during ECC and performed 5 cycles of single rescuer CPR on a recording mannequin. The participants were assigned to 2 groups: the dominant hand group (DH; n=40) and the non-dominant hand group (NH; n=29). The depth and rate of ECC were analysed to compare the effectiveness of ECC between 2 groups. Results The rate of ECC was significantly faster in the DH group (mean, 117.3 ±11.4/min) than in the NH group (mean, 110.9±12.2/min) (p=0.028). However, the depth of ECC in the dominant hand group (mean, 52.4±5.9 mm) was not significantly different from that in the non-dominant hand group (mean, 50.8±6.0 mm) (p=0.287). Similarly, the portion of ECC with inadequate depth in the dominant hand group (mean, 1.8±4.3%) was not significantly different from that in the non-dominant hand group (mean, 5.3±15.6%) (p=0.252). Conclusions ECC can be performed with an acceptably higher rate of compressions when the dominant hand of the novice rescuer is placed in contact with the sternum. However, the position of the dominant hand does not affect the depth of ECC. (Hong Kong j.emerg.med. 2014;21:382-386)
