This clinical investigation aims to collect data for algorithm development and testing of Vitacam as well as to later validate the system using a simultaneously collected, but segregated, hold-out validation dataset. Vitacam is a software medical device for measuring vital signs, manufactured by NE Device SW Oy. It analyses digital video recorded using a smart device with a camera to locate a subject's face and chest region. From both these regions of interest, the video is further analysed to obtain the heart rate, heartbeat intervals, respiratory rate and oxygen saturation. These measurements are used as inputs to clinical decision making. Vitacam uses remote photoplethysmography to obtain the heart rate and heartbeat intervals, and will build on this to obtain oxygen saturation using information from red-green-blue channels. The main focus of this study is to validate the oxygen saturation, heart rate and heartbeat intervals measured by Vitacam against gold standard references, applying the ISO 80601:2019 standard.

Accuracy of oxygen saturation measurements - Root Mean Square Error
Timeframe: A 30-45 minute period during which the participant is subjected to the de-saturation process
Accuracy of oxygen saturation measurements - Mean absolute error
Timeframe: A 30-45 minute period during which the participant is subjected to the de-saturation process
