1. A patient monitor comprising:
- a first input configured to receive a trend data signal indicative of trend data related to a first parameter signal, said first parameter signal indicative of one or more physiological parameters 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 responsive to a second physiological sensor monitoring said patient;
a plurality of predetermined limits for said parameter signals; and
a processor adapted to combine said trend data, determined values from said second parameter signal and said limits so as to generate an alarm output.

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.

11. 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 (12, 13, 14)

15. A system for indicating a diagnostic indication of a patient condition comprising:
-
a first sensor configured to measure a first physiological parameter and output an indication of trend data related to the first physiological parameter; a second sensor configured to measure a second physiological parameter different from said first physiological parameter and output an indication of trend data related to the second physiological parameter; and a processor which receives the outputs of the first and second sensors and determines a diagnostic indication of a patient condition from the outputs. - View Dependent Claims (16)
