1. A method of locating a blood pressure sensor over an underlying artery having a pulse, the method comprising:

  • positioning the blood pressure sensor at each of a plurality of locations above a known approximate location of the artery while applying hold down pressure at each location;

    wherein the blood pressure sensor has an active area which contacts a patient'"'"'s body and has a width greater than a width of the artery, and wherein the blood pressure sensor produces a single time-varying signal representative of pressure applied to the active area by the artery during a cardiac cycle;

    sensing pressure applied to the active area by the artery during a cardiac cycle with the sensor at each of the locations to produce at each location the time-varying signal representative of the pressure applied to the active area by the artery; and

    displaying an indication of maximum pressure signal sensed during each cardiac cycle at each location to aid in final positioning of the sensor.
