Brief Summary
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).

Outcome Measures
Primary Outcomes (1)
Specificity and sensitivity of the camera based prototype application (CBPA)
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)
1 year
Secondary Outcomes (1)
Upgrade of patient's ESI level due to CBPA (from Level 3 to 2)
1 year
Interventions
We measure Respiratory Rates in the Triage of Patients entering an Emergency Department by three different methods.
Eligibility Criteria
The study population will contain patients running through triage of the Emergency Department with an indication for vital sign assessment. The data will only be collected in the University Hospital of Basel.
You may not qualify if:
- Excluded will be (1) patients brought in by ambulance or helicopter, (2) unstable patients needing immediate medical treatment, (3) confused, restless, deaf patients having difficulty to follow the study instructions (4) Clear signs of refusal to participate the study.
