Method and system for determination of pulse rate
First Claim
Patent Images
1. A method of determining pulse rate of a patient comprising:
- determining pulse period data in a microprocessor from pulses that meet predetermined criteria, wherein the predetermined criteria are selected so that a minimum number of pulse periods can be used to determine pulse rate, and wherein the minimum number of pulse periods is equal to or greater than a minimum required number of pulse periods;
determining a median pulse period;
evaluating whether an earlier pulse period is within a predetermined threshold of the median pulse period;
identifying pulse periods that are equal to half or double the median pulse period; and
determining the pulse rate in the microprocessor from the pulse period data.

Abstract
A method and system for determining pulse rate of a patient are disclosed. The method and system include acquiring measured information for at least one pulse at a pressure step, determining and storing quality values for the at least one pulse at the pressure step, analyzing pulse matching criteria for the pressure step, and determining pulse rate based on the measured information, quality values, and pulse matching criteria.
