Randomized Controlled Trial Comparative Study
Dispatcher-assisted telephone cardiopulmonary resuscitation using a French-language compression-only protocol in volunteers with or without prior life support training: A randomized trial.
Due to the recent interest in hands-only protocols for dispatcher-assisted cardiopulmonary resuscitation (CPR) and the lack of any validated algorithms in French, our primary objective was to evaluate a new French-language protocol in terms of its efficacy to help previously untrained volunteers in performing basic life support efforts of appropriate quality, and secondarily to investigate its potential utility in subjects with previous training. ⋯ When used by dispatchers, this new French-language algorithm offers the opportunity to help previously untrained bystanders initiate CPR. The same protocol may serve to guide volunteers with prior basic life support training to reach their best CPR performance.

Randomized Controlled Trial Comparative Study
Performer fatigue and CPR quality comparing 30:2 to 15:2 compression to ventilation ratios in older bystanders: A randomized crossover trial.
We sought to compare bystander fatigue and CPR quality after 5min of CPR using the 30:2 vs. the 15:2 chest compression:ventilation ratios in a population of older participants. ⋯ In this study of older volunteers, the 30:2 CPR ratio resulted in similar objective measures of fatigue, but higher perceived fatigue than the 15:2 ratio. The 30:2 ratio resulted in proportionally more inadequate compressions.

Effectiveness of the new 'Mobile AED Map' to find and retrieve an AED: A randomised controlled trial.
Although early shock with an automated external defibrillator (AED) is one of the several key elements to save out-of-hospital cardiac arrest (OHCA) victims, it is not always easy to find and retrieve a nearby AED in emergency settings. We developed a cell phone web system, the Mobile AED Map, displaying nearby AEDs located anywhere. The simulation trial in the present study aims to compare the time and travel distance required to access an AED and retrieve it with and without the Mobile AED Map. ⋯ Although the new Mobile AED Map reduced the travel distance to access and retrieve the AED, it failed to shorten the time. Further technological improvements of the system are needed to increase its usefulness in emergency settings (UMIN000002043).

Randomized Controlled Trial Comparative Study
The effect of a cellular-phone video demonstration to improve the quality of dispatcher-assisted chest compression-only cardiopulmonary resuscitation as compared with audio coaching.
Bystander cardiopulmonary resuscitation (CPR) has shown to significantly improve the survival of cardiac-arrest victims. Dispatcher assistance increases the number of bystanders who perform CPR, but the quality of CPR remains unsatisfactory. This study was conducted to assess the effect of video coaching on the performance of CPR by untrained volunteers when compared with traditional audio instruction in simulated cardiac arrests. ⋯ Instructions from the dispatcher, along with a video demonstration of CPR, improved the time to initiate compression, the compression rate and the correct hand positioning. It also reduced the 'hands-off' events during CPR. However, emphasised instructions by video may be needed to increase the depth of compressions.
