Can a Software-Based Metronome Tool Enhance Compression Rate in a Realistic 911 Call Scenario Without Adversely Impacting Compression Depth for Dispatcher-Assisted CPR?

Unlabelled: IntroductionImplementation of high-quality, dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) is critical to improving survival from out-of-hospital cardiac arrest (OHCA). However, despite some studies demonstrating the use of a metronome in a stand-alone setting, no research has yet demonstrated the effectiveness of a metronome tool in improving DA-CPR in the context of a realistic 911 call or using instructions that have been tested in real-world emergency calls.HypothesisUse of the metronome tool will increase the proportion of callers able to perform CPR within the target rate without affecting depth.

The effects of video self-evaluation on skill acquisition with yoga postures.

This study evaluated the use of video self-evaluation and video feedback to increase the accuracy of yoga poses. The interventions were assessed in a multiple baseline design across behaviors with 2 adults. Results showed that video self-evaluation increased the accuracy of all poses, and video feedback further increased the accuracy of 1 pose for 1 participant.
