Smartwatches as chest compression feedback devices: A feasibility study.
Recently, there have been attempts to use smartphones and smartwatches as the feedback devices to improve the quality of chest compressions. In this study, we compared chest compression depth feedback accuracy between a smartphone and a smartwatch in a hands-only cardiopulmonary resuscitation scenario, using a manikin with a displacement sensor system. ⋯ The smartwatch-based chest compression depth feedback was more accurate than smartphone-based feedback.
