简要总结
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).
详细描述
For triage of emergency patients at the Emergency Department of the University Hospital Basel the emergency severity index (ESI) is used. At decision point "D" in the ESI-algorithm vital signs such as respiratory rate, heart rate and oxygen saturation are needed.
According to the guidelines the respiratory rate is visually counted for one minute (WHOrecommendation) by a triage nurse.
Simultaneously in addition to the visual counting, it is planned to measure the same vital sign as part of our study also through a camera-based prototype application (CBPA) and capnography as a gold standard.
Hence the triage process is not prolongated through our study, only completed and a guideline compliant procedure is ensured which is only performed in a relatively low percentage in the ED of the University Hospital Basel. Clinical decisions are exclusively based on the actual clinical standard of visual counting and are not influenced by the measurements of our study.
For the capnography, which were considered as the most accurate method, the patient wears a nasal sample line (Philips® Heartstart MRx mit Philips® Smart CapnoLine™PlusO2Long Oral/Nasal Sample Line).

结局指标
主要结局
Specificity and sensitivity of the camera based prototype application (CBPA)
时间窗: 1 year
In this study respiratory rates are obtained by 3 methods. 1. Camera based measurement, 2. with capnography and 3. with the WHO criterion standard of counting breaths for 1 Minute (18 measurements in whole). We want to study the Specificity and sensitivity of the CBPA compared to the gold standard (capnography)
次要结局
- Upgrade of patient's ESI level due to CBPA (from Level 3 to 2)(1 year)
