<p>A non-invasive apparatus and method for monitoring the blood pressure of a subject detects a blood pressure pulse signal at both a first and second location on the subject's body. The elapsed time between the arrival of corresponding points of the blood pressure pulse signal at the first and second locations is determined, and the estimated blood pressure determined by performing the following calculation: P = a + b ln(T), where a and b are constants dependent upon the nature of the subject and the signal detecting devices. The system is calibrated before the blood pressure calculation is made.</p> |
