1. A measurement device for determining blood pressure, the measurement device comprising:

  • an exciter, configured to perturb at least one of volume and pressure of a patient'"'"'s artery with an oscillating perturbation signal, the oscillating perturbation signal oscillating at an exciter frequency;

    a detector configured to detect a signal indicative of an oscillation response to the oscillating perturbation signal;

    a band-pass filter set at a multiple of the exciter frequency and configured to provide a filtered signal output in response to the detected signal; and

    a processor, coupled to the band-pass filter, wherein the processor is configured to identify a time when transmural pressure is approximately equal to zero.
