1. An alarm processor comprising:
- a signal input responsive to a physiological parameter;
a plurality of parameter processors responsive to said signal input so as to provide a plurality of measurements of said parameter, said measurements having differing characteristics;
an alarm condition applicable to at least one of said measurements so as to define a limit for said parameter; and
an alarm indicator operating on said measurements and said alarm condition so as to provide an alarm output that changes state to indicate that said parameter may have exceeded said limit.

Abstract
An alarm processor has a signal input responsive to a physiological parameter and a plurality of parameter processors responsive to the signal input so as to provide a plurality of different measurements of the parameter. In addition, the alarm processor has an alarm condition applicable to at least one of the measurements so as to define a limit for the parameter. Further, the alarm processor has an alarm indicator operating on the measurements and the alarm condition so as to provide an alarm output that changes state to indicate that the parameter may have exceeded the limit.

10. A alarm method comprising the steps of:
-
inputting a sensor signal responsive to a physiological parameter;
processing said sensor signal to provide an smoothed measurement of said parameter and a predictive measurement of said parameter; and
triggering an alarm based on both said smoothed measurement and said predictive measurement. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An alarm processor comprising:
-
a processor means for deriving a plurality of measurements of a physiological parameter;
a condition means for specifying a limit on said parameter, said condition means applied to at least one of said measurments; and
an indicator means for generating an alarm in response to said condition means and said measurement means. - View Dependent Claims (18, 19, 20)
