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.
Claims8
A patient monitor comprising one or more hardware processors configured to:
- receive at least one pulse oximetry parameter responsive to irradiation of a tissue site with an optical sensor;
- receive a secondary parameter responsive to measurement from a second sensor, wherein the secondary parameter is different from the pulse oximetry parameter received by the optical sensor;
- generate a variable threshold for the pulse oximetry parameter based on the trend property of the secondary parameter;
- compare the pulse oximetry parameter with the variable threshold corresponding to physiological condition of a patient;
- and
- generate a diagnosis decision based on the comparison of the pulse oximetry parameter with the variable threshold.
