In emergency medicine and urgent care, the first assessment and triage are crucial to examine the severity of disease, condition or injury, for prioritizing tests and procedures. Vital signs are fundamental in this process and are investigated in all validated clinical assessment methods. This proposal aims to develop a camera-based system based on photoplethysmography enabling non-contact scanning of vital signs, specifically pulse rate and blood pressure (BP), replacing the conventional setup of devices that is time-consuming to operate and requires physical contact. The proposed solution will work by recording a video for a few seconds using a high-speed RGB camera. This video will then be processed by image and signal processing algorithms, and machine learning for categorizing levels of blood pressure and risk classes, to trigger a flag in case if a patient is in need of emergency care, enabling the staff in the care unit to decide on the level of caution to be taken.
