REDUCING NUISANCE ALARMS

摘要

Embodiments disclosed herein may describe systems and methods for reducing nuisance alarms using probability and/or accuracy of a measured physiological parameter, such as the pulse rate or SpO2 measurement generated by a pulse oximeter. Embodiments may include methods for adjusting a predetermined alarm threshold based on the probability distribution of the estimated pulse rate and/or oxygen saturation of a patient's blood.

主权项

1. A method for generating an alarm indicating that a physiological parameter has exceeded a predetermined threshold, the method comprising:
calculating a probability distribution of an actual value of the physiological parameter based at least in part upon data; identifying the predetermined threshold associated with the physiological parameter; and generating the alarm based at least in part upon the predetermined threshold and the probability distribution.
