Background |
Chest compression (CC) quality is associated with rescuer posture and body weight. We designed a Kinect module-based real-time audiovisual feedback (AVF) device to investigate the relationship between rescuer posture, body weight, and CC quality.
Methods |
A total of 100 healthcare professionals were enrolled as participants in this randomized trial. A Kinect-based sensor system was used to monitor the depth and rate of CC and provide further real-time feedback. All participants were asked to perform continuous CC on a manikin with and without feedback for 2min individually in either a kneeling or standing position.
Results |
A kneeling posture can provide higher rate of CC than a standing posture can (111.4±22.6 per minute vs. 99.1±18.9per minute, p value=0.005). Real-time AVF feedback can provide a better compression depth, rate, and effective compression ratio (6.16±1.88cm vs. 5.54±1.89cm, p value=0.02; 103.2±21.0/min vs. 96.7±25.8/min, p value=0.03; 62.6±28.0% vs. 51.0±33.2%, p value=0.004). Regardless of the effect of real-time feedback, the CC depth correlated to the rescuers' body weight. Rescuers who weighed below 71kg benefited from the Kinect module-based real-time AVF device in terms of improved CC quality.
Conclusion |
The Kinect-based AVF device can significantly improve CC quality in manikin training in rescuers with their body weight<71kg.
