Summary

This study aims to develop an automated and real-time non-contact vital sign measurement system using cameras. It will collaborate with physicians from National Taiwan University Hospital to conduct measurements during outpatient visits or hospitalizations. This allows physicians to non-invasively measure multiple vital signs (such as heart rate, blood pressure, and oxygen saturation) upon your entry to the outpatient clinic or hospital. Simultaneously, the measurements will be verified using commercially available contact-based instruments. The research outcomes of this project aim to enhance the convenience, safety, and comfort of vital sign measurements for outpatient visits, hospitalizations, and long-term care in the future.

Detailed description

The experiment of this project is to use a camera to measure blood pressure, blood oxygen saturation and pulse, record images of the face and hands, and use the image processing algorithm we developed to extract the signals from the images to estimate blood pressure and blood oxygen Concentration and pulse values. The experimental process will be carried out in accordance with the "experimental setup, blood pressure measurement, and blood oxygen saturation measurement" process. At the same time, commercially available measurement instruments will be used to conduct clinical experiments and verification. The experimental setup diagram is shown in Figure 1. Blood pressure and blood pressure The oxygen saturation measurement process is shown in Figure 2. The blood pressure measurement process takes about 10 minutes, and the blood oxygen measurement process takes about 5 minutes.
