Noninvasive multi-parameter patient monitor

A patient monitor configured to indicate abnormal behavior of a plurality of physiological parameters, the 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, wherein the plurality of physiological parameters comprise at least one of carboxyhemoglobin, methemoglobin, hemoglobin, oxygen saturation, and fractional saturation,
• 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,
• cause a display device in communication with the processor to display thereon the wellness qualitative indication within at least one of a plurality of wellness regions of a patient wellness graph, wherein the plurality of wellness regions correspond 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,
• cause the display device to display thereon 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
• activate a caregiver alert upon the occurrence of a predetermined event.
