Abstract
A threshold detector for detecting the recurrence of a respiration event by comparing a filtered respiration signal to an adjustable threshold level. The adjustable threshold level is maintained at a value sufficient to substantially prevent the detector from indicating that a respiration event has occurred due to residual cardiovascular artifact being present in the filtered respiration signal.
