| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| spectral imaging | Other | non-contact, non-invasive hyperspectral and multispectral imaging without a diagnostic test | ||
| photoplethysmography | Other | non-invasive pulse oximetry without a diagnostic test |
| Measure | Description | Time Frame |
|---|---|---|
| RGB video data | true color video data (10 bit per channel [red, green, blue]) from tongues and fingers | 16 minutes |
| hyperspectral data | false color parameter images, representing the oxygenation in %; the perfusion; the hemoglobin, water, and fat content of tissue in arbitrary units betwenn 0 and 100 from tongues and fingers (imaged areas have to correspond to RGB video data) | 16 minutes |
| multispectral video data | true color video data (10 bit per channel [red, green, blue]) from tongues and fingers (imaged areas have to correspond to RGB video data) | 16 minutes |
| plethysmographic wave | numerical value in arbitrary values representing the amount of transmitted/reflected light over time through fingers or earlobes or from the forehead | 5 minutes |
| pulse | frequency in bpm (beats per minute) or Hz (Hertz) | 5 minutes |
| pulsation index | ratio between pulsating and non-pulsating tissue components in % | 5 minutes |
| SpO2 | oxygenation of arterial blood in %, measured with a pulse oximeter | 5 minutes |
