Respiratory Rates - Accuracy of Contact-free Monitoring of Respiratory Rates

Respiratory rate is an important predictor for many clinical outcomes in Emergency Medicine. Nevertheless it's measurement is often omitted as it is time-consuming and cumbersome. It is the only vital sign that is not routinely assessed by a device. In a pilot study was showed that a camera based monitoring system measures reliably respiratory rates in healthy volunteers. The goal of this study is to test the accuracy of the same system in real patients in the triage setting of an Emergency Department (ED).
