A non-contact measurement method for estimating blood pressure using video pulse waves has been developed. During fluctuation in blood pressure caused by respiratory arrest, the video pulse waves were measured by using a video camera to calculate the pulse transit time difference (PTTD) from a proximal part to a distal part with respect to the heart. Blood pressure was estimated by a multivariate...
In this study, an easy system for monitoring dynamic blood perfusion patterns and the pulse wave velocity (PWV) has been developed by processing video images of a human body to assess blood circulation for daily management of physical conditions or for detecting persons in poor physical condition in public places. The experiment suggested that this tool can be used to easily evaluate the PWV; however,...
