Knowledge and attitudes of Singapore schoolchildren learning cardiopulmonary resuscitation and automated external defibrillator skills.

Introduction: Victims of out-of-hospital cardiac arrests require timely cardiopulmonary resuscitation (CPR) and early defibrillation. Callers to emergency medical services are asked to provide dispatcher-guided responses until an ambulance arrives. Knowing what to expect in such circumstances should reduce both delay and confusion.

Measuring the effectiveness of a novel CPRcard™ feedback device during simulated chest compressions by non-healthcare workers.

Introduction: There is a need for a simple-to-use and easy-to-carry CPR feedback device for laypersons. We aimed to determine if a novel CPRcard™ feedback device improved the quality of chest compressions.

Methods: We compared participants' chest compression rate and depth with and without feedback.
