Abstract
A method and apparatus for detecting an alarm in a patient monitoring system. The patient monitoring system executes the steps of measuring values representative of a physiological parameter of a patient, determining whether the parameter values are within safe zone limits, initiating calculation of a trend vector that is a function of changes in the parameter values, when the parameter values go outside the safe zone limits, comparing the trend vector with an alarm limit function and issuing an alarm when the trend vector exceeds the alarm limit function. The alarm limit function typically varies with time after initiating calculation of the trend vector. The trend vector is calculated for each measured value until an alarm is issued or the parameter value returns to within the safe zone limits.
