Claim 6:
7. The apparatus of claim 6, wherein the processor is further configured to:
multiply a difference between a reference systolic blood pressure (SBP) and a reference mean arterial pressure (MAP) by a normalized feature for SBP of the obtained second pulse wave signal, to obtain a variation in the SBP, wherein the reference SBP and the reference MAP are determined at the time of calibration of the apparatus; and
multiply a difference between the reference MAP and a reference diastolic blood pressure (DBP) by a normalized feature for DBP of the obtained second pulse wave signal, to obtain a variation in the DBP, wherein the reference DBP is determined at the time of calibration of the apparatus.
