1. A patient monitor comprising:
- a first input configured to receive a first parameter signal, said first parameter signal indicative of a first physiological parameter of a patient and said first parameter signal responsive to a first physiological sensor monitoring said patient;
a second input configured to receive a second parameter signal, the second parameter signal indicative of a second physiological parameter of the patient and responsive to a second physiological sensor monitoring said patient;
a processor responsive to said first and second inputs to determine trend data based on one or more of the first parameter signal and the second parameter signals and, to generate an alarm output based at least in part on said trend data; and
a pattern detector having a detection output responsive to said first parameter signal,said diagnostic indication of a patient condition or alarm output responsive to said detection output and said trend data.

Abstract
A physiological parameter system has one or more parameter inputs responsive to one or more physiological sensors. The physiological parameter system may also have quality indicators relating to confidence in the parameter inputs. A processor is adapted to combine the parameter inputs, quality indicators and predetermined limits for the parameters inputs and quality indicators so as to generate alarm outputs or control outputs or both.

7. A physiological parameter method comprising the steps of:
-
inputting trend data related to a parameter, the parameter responsive to a physiological sensor; inputting a quality indicator related to data confidence for said trend data; outputting a control signal from the combination of said trend data and said quality indicator, wherein said control signal is adapted to affect the operation of a medical-related device. - View Dependent Claims (8, 9, 10)
