ABSTRACT
A continuous cuffless non-contact blood pressure (BP) measurement scheme using Doppler radar is proposed. This non-contact BP estimation scheme uses the periods in which the heart beats and periods in which the heart contracts. These periods are obtained using Doppler radar signals. Diastolic BP (DBP) was estimated using the period in which the heart contracts. Pulse pressure (PP) was estimated using one period in which the heart beats and one period in which the heart contracts. Systolic BP (SBP) was obtained by the sum of the estimated DBP and PP. The correlation of the estimated BP and the BP acquired by the BP monitor was calculated. The correlation coefficients were 0.79 for SBP, 0.88 for DBP, and 0.81 for PP. The BP was successfully measured in a contactless manner.
