PULSE AND CONFIDENCE INDICATOR DISPLAYED PROXIMATE PLETHYSMOGRAPH
First Claim
Patent Images
1. A method of indicating pulse occurrences and 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 pulse 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; and
modifying said visual pulse indicator, said modification responsive to said measurement of confidence.

9. 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 pulse occurrences and signal quality when a displayed plethysmograph alone may not be a sufficient visual indicator, 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 modified visual pulse 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, said modification to said visual pulse indicator being responsive to said measurement of confidence. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
