Noninvasive multi-parameter patient monitor
First Claim
1. A method, comprising:
- noninvasively, electronically determining measured values of a plurality of physiological parameters including at least a first physiological parameter and a second physiological parameter, wherein the determining is performed by processing one or more signals with one or more signal processors, said signals responsive to attenuation of light by body tissue of a monitored patient;
electronically combining at least one measured value of the first physiological parameter and at least one measured value of the second physiological parameter into a wellness qualitative indication;
displaying the wellness qualitative indication within a patient wellness area of a display device as a line, wherein the location of a distal end of the line and the slope of the line indicate a patient wellness level;
providing an alarm threshold for the first physiological parameter;
altering the alarm threshold for the first physiological parameter based on the at least one measured value of the second physiological parameter satisfying a threshold value; and
activating a caregiver alert upon the occurrence of a predetermined event, wherein the predetermined event is based on the at least one measured value of the first physiological parameter satisfying in the altered alarm threshold.

Abstract
Embodiments of the present disclosure include a handheld multi-parameter patient monitor capable of determining multiple physiological parameters from the output of a light sensitive detector capable of detecting light attenuated by body tissue. For example, in an embodiment, the monitor is capable of advantageously and accurately displaying one or more of pulse rate, plethysmograph data, perfusion quality, signal confidence, and values of blood constituents in body tissue, including for example, arterial carbon monoxide saturation (“HbCO”), methemoglobin saturation (“HbMet”), total hemoglobin (“Hbt”), arterial oxygen saturation (“SpO2”), fractional arterial oxygen saturation (“SpaO2”), or the like. In an embodiment, the monitor displays a line associated with a patient wellness level.

11. A patient monitor, comprising:
-
a sensor port configured to receive one or more signals from a sensor, wherein the signals are responsive to attenuation of light by body tissue of a monitored patient; and a processor in communication with the sensor port and configured to; noninvasively, electronically determine measured values of a plurality of physiological parameters including at least a first physiological parameter and a second physiological parameter using the one or more signals received from the sensor, electronically combine at least one measured value of the first physiological parameter and at least one measured value of the second physiological parameter into a wellness qualitative indication comprising a line, cause a display device in communication with the processor to display thereon the line, wherein the slope of the line indicates a patient wellness level, provide an alarm threshold for the first physiological parameter, alter the alarm threshold for the first physiological parameter based on the at least one measured value of the second physiological parameter satisfying a threshold value, and activate a caregiver alert upon the occurrence of a predetermined event, wherein the predetermined event is based on the at least one measured value of the first physiological parameter satisfying the altered alarm threshold. - View Dependent Claims (12, 13, 14, 15, 16)
