The project is devoted to development of remote touchless monitoring of blood pressure, pulse wave propagation velocity, heart rate, heart rate variability and respiratory rates. This technology is important for ICUs, long care facilities, clinics during pandemic where breathing and circulatory conditions are critical to control. The hardware/software prototype that was created can perform monitoring 24/7, even overnight exploiting a low power near infrared light source. This project is progressing in collaboration with Kagoshima University Hospital and Hamamatsu Corporation, Japan. The example of data collection of spatially resolved 2D pulse wave monitoring is shown: Pulse Transit Time (PTT) is determined as the maximum of the cross correlation between 2 segments of tissue to calculate Pulse Wave propagation velocity (PWV) and the blood pressure is computed via further transforms of the data.
