Method for continuous determination of mean, systolic and diastolic arterial blood pressure by measurement of the pulse transition time using electrodes measuring impedance of separate body regions

摘要

Method for continuous determination of the arterial blood pressure uses the pulse transition time (PTT) in which the time of pulse arrival at two different body points is measured and then the difference between the two determined, from which a value for blood pressure is determined. Accordingly each sensor has two electrodes (1-6) that measure the impedance of the body region and the mean arterial blood pressure from the corresponding PTT. The invention also relates to a corresponding device.
