Randomized Controlled Trial Comparative Study
A manually powered mechanical resuscitation device used by a single rescuer: a randomised controlled manikin study.
The goal of this randomized, open, controlled crossover manikin study was to compare the performance of "Animax", a manually operated hand-powered mechanical resuscitation device (MRD) to standard single rescuer basic life support (BLS). ⋯ Single rescuer cardio-pulmonary resuscitation with the manually operated MRD was superior to standard BLS regarding chest compressions in this simulation study. The MRD delivered a higher minute-volume but did not achieve the recommended minimal volume. Further clinical studies are needed to test the MRD's safety and efficacy in patients.

Randomized Controlled Trial Comparative Study
A randomised control trial comparing two techniques for locating chest compression hand position in adult Basic Life Support.
Chest compressions performed correctly have the potential to increase survival post cardiac arrest. The 2005 European Resuscitation Council (ERC) guidelines altered and simplified instructions for hand position placement to increase the number of chest compressions performed. This randomised controlled trial compares chest compression efficacy (hand position and number of effective chest compressions) after training using the 2005 guidelines or the 2005 guidelines with a hand position modification based on 2000 ERC guidelines. ⋯ The use of landmark measurement techniques in hand placement for external chest compressions does not have a detrimental effect on the number of chest compressions performed during BLS and increases correct hand positioning.

Effects and limitations of an AED with audiovisual feedback for cardiopulmonary resuscitation: a randomized manikin study.
Correctly performed basic life support (BLS) and early defibrillation are the most effective measures to treat sudden cardiac arrest. Audiovisual feedback improves BLS. Automated external defibrillators (AED) with feedback technology may play an important role in improving CPR quality. The aim of this simulation study was to investigate if an AED with audiovisual feedback improves CPR parameters during standard BLS performed by trained laypersons. ⋯ Use of an AED's audiovisual feedback system improved some CPR-quality parameters, thus confirming findings of earlier studies with the notable exception of decreased compression depth, which is a key parameter that might be linked to reduced cardiac output.

Randomized Controlled Trial Comparative Study
Combining video instruction followed by voice feedback in a self-learning station for acquisition of Basic Life Support skills: a randomised non-inferiority trial.
Current computerised self-learning (SL) stations for Basic Life Support (BLS) are an alternative to instructor-led (IL) refresher training but are not intended for initial skill acquisition. We developed a SL station for initial skill acquisition and evaluated its efficacy. ⋯ Compression skills acquired in a SL station combining video-instruction with training using voice feedback were not inferior to IL training.
