ABSTRACT:
An apparatus for monitoring the respirations of a patient includes a device for generating a respiration signal having amplitude modulations representative of patient respirations, as well as respiration artifacts, and a processor coupled to the respiration signal generating device and responsive to the respiration signal for 1) detecting inflection points in the respiration signal; 2) determining if either one of a portion of the respiration signal which precedes or follows each detected inflection point has a slope which exceeds a predetermined slope threshold level which is indicative of a respiration artifact; and 3) developing breath indication information based upon the slope threshold determination.
