Comparison between an instructor-led course and training using a voice advisory manikin in initial cardiopulmonary resuscitation skill acquisition

Abstract

Objective We compared training using a voice advisory manikin (VAM) with an instructor-led (IL) course in terms of acquisition of initial cardiopulmonary resuscitation (CPR) skills, as defined by the 2010 resuscitation guidelines.Methods This study was a randomized, controlled, blinded, parallel-group trial. We recruited 82 first-year emergency medical technician students and distributed them randomly into two groups: the IL group (n = 41) and the VAM group (n = 37). In the IL-group, participants were trained in "single-rescuer, adult CPR" according to the American Heart Association's Basic Life Support course for healthcare providers. In the VAM group, all subjects received a 20-minute lesson about CPR. After the lesson, each student trained individually with the VAM for 1 hour, receiving realtime feedback. After the training, all subjects were evaluated as they performed basic CPR (30 compressions, 2 ventilations) for 4 minutes. ResultsThe proportion of participants with a mean compression depth ≥ 50 mm was 34.1% in the IL group and 27.0% in the VAM group, and the proportion with a mean compression depth ≥ 40 mm had increased significantly in both groups compared with ≥ 50 mm (IL group, 82.9%; VAM group, 86.5%). However, no significant differences were detected between the groups in this regard. The proportion of ventilations of the appropriate volume was relatively low in both groups (IL group, 26.4%; VAM group, 12.5%; P = 0.396).Conclusion Both methods, the IL training using a practice-while-watching video and the VAM training, facilitated initial CPR skill acquisition, especially in terms of correct chest compression.

Effect of cardiopulmonary resuscitation training towards cardiac arrest emergency knowledge upon students at Student Health Association of Universitas Gadjah Mada, Indonesia

“…9 Furthermore, it was also explained that the application of practice while watching and hands-on experience method will improve psychomotor skill of CPR. 5 CPR training for students reduced fear in doing first aid upon emergency case. Students had quite enough cognitive and physical skills to play role as first aider in emergency case specifically in cardiac arrest.…”

“…4 Hence, education and training for first aider becomes an essential matter. 5 Training and education on CPR will be more optimal when it is given to students. Students have been capable in receiving materials regarding first aid and emergency prevention.…”

Effectiveness of first-aid training in school among high school students in Kulon Progo, Indonesia

“…The use of the method of practice while watching and hands-on experience would increase the psycho-motoric skill in CPR. 6 The first-aid training to the senior high school students decreased the fear in giving the rescue in the cases of emergency. The senior high school students possessed enough cognitive and physical skill as the first responder of the emergency case, especially cardiac arrest.…”

“…5 Therefore, the education and training for the first responder became an important matter. 6 The training and education about CPR will be more optimum if it is given to students in the level of senior high school. The students in the age of more or less 17 years are able to understand the materials of the first aid and handling the emergency situation.…”

“…322,326 One study showed worse CPR performance at the conclusion of training, although this study has a high risk of bias because of unclear outcome definitions and the use of the audiovisual feedback system to replace an instructor. 321 One observational study found improvements in delivered chest compression rate (118.61 +/10.74 compressions/min versus 137.72 AE 11.14 compressions/min; P < 0.001), with the use of a feedback device during training of student teachers. 325…”
