Method and Apparatus for the Non-Invasive Measurement of Pulse Transit Times (PTT) |
摘要 |
Method and apparatus for measuring a pulse transit time (PTT) value of a subject, 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 said at least one ROI. The method allows for the non-invasive and continuous measurement of the PTT value and arterial blood pressures.
