ABSTRACT:
An electronic blood pressure meter including a cuff, a pressure system for pressurizing and evacuating the cuff, a pressure sensor for detecting the pressure within the cuff, a pulse wave parameter extraction circuit and a blood pressure determining circuit. The pulse wave parameter extraction circuit extracts the maximum level difference in the pulse wave component of the cuff pressure over a certain time intervals and also provides pulse wave maximum and minimum values corresponding to the maximum and minimum values of the pulse wave components over each of the time intervals chosen. The electronic blood pressure meter may also include circuitry for finding maximum and minimum values on each of the higher and lower cuff pressure sides of the cuff and deriving blood pressure measuring readings therefrom.
