A cuffless (in the sense that a pressurized upper arm cuff is not required) portable monitor for the continuous measurement of blood pressure, pulse rate and pulse wave velocity includes a pair of capacitative sensors 1, 2 located above the artery in the lower arm at a predetermined distance from each other. The time separated signals from the capacitative sensors that are generated in the sensors at each arterial pressure pulse are converted into pulse width modulated signals by integrated circuit 5 and digital signals indicative of the blood pressure, pulse rate and pulse wave velocity by the microprocessor 6.
