17. A method of indicating signal quality in an electronic patient monitor when a displayed plethysmograph alone may not be a sufficient visual indicator, the method comprising:
-
electronically receiving a sensor output signal indicative of light attenuated by pulsing blood of a patient; determining with a signal processor plethysmographic data responsive to said sensor output signal; determining with said signal processor a measurement of confidence that said plethysmographic data accurately reflects physiological parameters occurring in said patient; displaying said plethysmographic data on a display of a patient monitoring device; displaying a visual indicator in proximity to said plethysmographic data; and modifying a color of said visual pulse indicator, said modification responsive to said measurement of confidence. - View Dependent Claims (18, 19, 20, 21, 22)

23. An electronic patient monitor including a signal processor communicating with a noninvasive optical sensor and a display device responsive to measurements and calculation made by said signal processor, said patient monitor configured to indicate signal quality, the monitor comprising:
-
a sensor signal input receiving a sensor output signal indicative of light attenuated by pulsing blood of a patient; a signal processor receiving said sensor output signal, determining plethysmographic data responsive to said sensor output signal, determining a measurement of confidence that said plethysmographic data accurately reflects physiological parameters occurring in said patient; and a display device displaying said plethysmographic data, displaying a visual indicator in proximity to said plethysmographic data to indicate to a caregiver which of said displayed plethysmographic data corresponds to an occurrence of a pulse of said patient, wherein a color of the visual indicator is dynamically modified responsive to said measurement of confidence. - View Dependent Claims (24, 25, 28, 29)
