Abstract
A method is disclosed for continuously monitoring a blood pressure measurement using a sensor connected by a hydraulic link to an arterial catheter, the method includes determining the dynamic parameters of the link, analyzing the frequency content of the incident signal, detecting one of the following situations: (a) ability of the link to transmit the incident signal with a distortion below a threshold, (b) ability of the link to transmit the incident signal with a distortion above the threshold and possibility of correcting the measured signal, (c) inability of the link to transmit the incident signal with a distortion below the threshold and impossibility of correcting the measured signal, periodic application of a mechanical action to the tubing providing the hydraulic link.
