Analysis of the contour of the peripheral pulse to assess arterial properties was first described in the nineteenth century. The reference technique to estimate central blood pressure (CBP), non-invasively, is by analyzing the radial pressure pulse acquired using a tonometer and then to establish a transfer function relating the radial pressure to the CBP. An alternative technique utilizes a volume pulse. This may conveniently be acquired optically from a finger. This technique deserves further consideration because of its simplicity and ease of use. The objective is to establish a transfer function estimating the central blood pressure (CBP), calibrated with a brachial pressure cuff and using the parameters obtained with the contour analysis of the photoplethysmographic pulse measured at the finger with the pOpmètre^® system. We positioned the photodiode sensor on the finger, insuring that the sensor's lens is in contact with the finger. Brachial blood pressure measurements was performed with a standard cuff. The central blood pressure values measured with Sphygmocor used as the reference values. Multiple regression analysis was done to establish the transfer functions. Sixty-nine subjects were included: 24 healthy subjects and 45 patients with essential hypertension aged 33±8years and 59±17years respectively. The correlation between the estimated central systolic pressure (CSP) and the reference one, was good and significant (r²=0.91; P<0.0001). A better correlation was found in terms of central diastolic pressure (CDP) (r²=0.92; P<0.0001). The Bland and Altman analysis, mean difference was 4mmHg P<0.0001 (CSP) versus 3mmHg P<0.0001 (CDP), the standard deviation of the difference was 5mmHg (CSP) versus 4mmHg (CDP), classifying the estimation as good agreement. The estimation of the central blood pressure with the finger pulse qualifies as good agreement with the reference technique for the central systolic and diastolic pressure estimation.
