Previous studies have demonstrated the potential for using smartwatches with a built-in accelerometer as feedback devices high-quality chest compression during cardiopulmonary resuscitation. However, to best of our knowledge, no previous study has reported effects this on compressions in action. A randomized, parallel controlled 40 senior medical students was conducted examine effect via smartwatch resuscitation manikins. application developed smartwatch, which visual provided depth and rate. Vibrations from were used indicate The participants randomly allocated intervention control groups, they performed manikins 2 min continuously or without feedback, respectively. proportion accurate (≥5 cm ≤6 cm) assessed primary outcome, depth, rate, complete decompression (≤1 residual leaning) recorded secondary outcomes. group significantly higher than that (64.6±7.8% versus 43.1±28.3%; p = 0.02). mean rate decompressions did not differ between two groups (all p>0.05). Cardiopulmonary resuscitation-related could provide assistance respect ideal range can easily be applied patients out-of-hospital arrest by rescuers who wear smartwatches.
