ABSTRACT:
A method of operating a non-invasive blood pressure (NIBP) monitor that includes a blood pressure cuff and a pressure transducer. The method initially inflates the blood pressure cuff to a level above systolic pressure and begins to deflate the pressure cuff using a continuous or linear deflation technique. During the linear deflation of the pressure cuff, the oscillation pulses from the pressure transducer are obtained and compared to predicted pulse estimates. If the obtained oscillation pulses vary from the predicted pulse estimates, the linear deflation technique is interrupted and the pressure cuff is then deflated in a sequence of distinct pressure steps. During each pressure step, the oscillation pulses are obtained and the pressure cuff is not deflated to the next pressure step until the oscillation pulses correspond to each other.
