Noninvasive multi-parameter patient monitor
First Claim
1. A method of indicating abnormal behavior of a plurality of physiological parameters, the 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 plurality of physiological parameters comprises at least one of carboxyhemoglobin, methemoglobin, hemoglobin, oxygen saturation, and fractional saturation, and 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 on a patient monitor a patient wellness graph and a plurality of wellness regions within the patient wellness graph, the plurality of wellness regions corresponding to measurement levels of the at least one measured value of the first physiological parameter and the at least one measured value of the second physiological parameter;
displaying the wellness qualitative indication within at least one of the plurality of wellness regions;
displaying a line associated with the wellness qualitative indication and an axis of the wellness graph, wherein the slope of the line and the location of the wellness qualitative indication within the at least one of the plurality of wellness regions indicate a patient wellness level; and
activating a caregiver alert upon the occurrence of a predetermined event.

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 advantageously includes a plurality of display modes enabling more parameter data to be displayed than the available physical display real estate.
