摘要:
A method for estimating blood pressure (BP) values comprises: measuring at a first PTT value, a second PTT value, and further PPT values using a method comprising measuring a first arterial pressure pulse arrival time (PAT) and measuring a second PAT value; calculating a PTT value from the difference between the first PAT value and the second PAT value; processing a sequence of electrical impedance tomography (EIT) images to identify at least one region of interest (ROI); and estimating at least one of the first and second PAT value from the variation of impedance value determined from the at least one ROI. The method allows for the non-invasive and continuous determination of the PB values by using a calibration factor.
