Patient alarm detection using target mode
First Claim
1. A patient monitoring system comprising:
- a sensor for measuring values of a physiological parameter; and
a processor coupled to said sensor for processing said measured parameter values measured by said sensor, said processor comprising;
means for setting target limits of the physiological parameter in response to user selections;
means for initiating a target mode after setting of said target limits;
means for calculating time-varying dynamic limits based on the current value of the physiological parameter and on the target limits of the physiological parameter;
means for comparing said measured parameter values with said dynamic limits in said target mode; and
means for generating an alarm when any of said measured parameter values falls outside said dynamic limits.

Abstract
A method and apparatus for detecting an alarm in a patient monitoring system during the transient period which occurs after performing a procedure that intentionally alters the patient'"'"'s state. The patient monitoring system executes the steps of initiating a target mode when the user sets target limits of a physiological parameter, establishing dynamic limits that vary with time, comparing measured parameter values with the dynamic limits, and generating an alarm when any of the measured parameter values falls outside the dynamic limits. The target mode is terminated when any of the measured parameter values falls within the target limits. The dynamic limits ensure that the physiological parameter is monitored during the transient period after an intervention procedure, without generating false alarms.
