1. A method of providing cohesive physiological parameter trend data through a change in measurement site, the method comprising:
- obtaining measurements of a physiological parameter from a first measurement site of a patient and determining trend information from the measurements of the physiological parameter from the first measurement site during a first time period;
obtaining measurements of the physiological parameter from a second measurement site of a patient and determining trend information from the measurements of the physiological parameter from the second measurement site during a second time period different from the first time period;
determining a physiological trend offset for the second trend information based on the trend information from the first measurement site.

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.

10. A system for indicating a wellness state of a patient comprising:
-
a first sensor configured to measure a first physiological parameter and output an indication of 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 the second physiological parameter; and a processor which receives the outputs of the first and second sensor, determines an indication of wellness from the outputs, and outputs an indication of wellness to a display device. - View Dependent Claims (11)
