Evaluating arterial pressure, vasomotor activity and their response to diagnostic tests

摘要

Method and system for evaluating arterial pressure waves, vascular properties, as well as for diagnostic, physiological and pharmacological testing using various combinations of the following data acquisition and processing steps (some of the steps are optional): 1. Perturbing arterial pressure from its steady state. 2. Measuring the dynamics of at least one parameter related to the passage of arterial pressure waves along blood vessels. 3. Characterizing the magnitude and functional relation of changes in parameters described above in relation to changes in blood pressure during its displacement from and/or return to the steady state. 4. Classifying (comparing) the individual functional relation described above with a databank of parameters/functional relations for different states of vasomotor activity.

1. A method for dynamical evaluation of vascular properties and their response to interventions, said method comprising:
placing at least one sensor adapted for measuring at least two cardiovascular signals in the vicinity of at least one major blood vessel; displacing at least parameter of arterial pressure wave and vasomotor activity from its steady state using at least one physiological, psychophysiological or pharmacological maneuver; monitoring physiological signals; and processing said physiological signals to determine at least one parameter value and pattern of an individual's functional relationship between arterial pressure wave, vasomotor activity and calibrated arterial pressure.
