Abstract
A method for measuring blood pressure during a limited number of blood pressure cycles at an area overlying an artery of a living subject, includes applying a pressure (P) to the artery for occluding the artery in response to a pressure signal. Subsequently the pressure is released to re-open the artery in response to a pressure release signal. A delay time is computed, by comparing a first time duration with a second time duration. The delay time is from a reference point in time after which a next pressure release signal is to be supplied to a device for applying a pressure. A pressure to be applied to the artery in a next measuring cycle is computed. Subsequently a pressure signal and a pressure release signal corresponding to the computed pressure and delay time are supplied to the device for applying a pressure.
