Patent Images
1. A patient monitor user interface comprising:
- an optical sensor configured to transmit light having multiple wavelengths into a tissue site and generate a sensor signal responsive to the transmitted light after attenuation by pulsatile blood flow within the tissue site;
a patient monitor in communications with the sensor signal so as to generate multiple parameter measurements responsive to the sensor signal, the patient monitor configured as a handheld device and including a color display, a plurality of user activated soft keys adjacent the color display and a plurality of icons provided on the color display proximate and corresponding to the soft keys;
an oxygen saturation measurement expressed as a first number;
a pulse rate expressed as a second number; and
a carboxyhemoglobin measurement expressed as a third number, wherein the first through third numbers are presented on the color display as a first through a third color, respectively.

Abstract
A patient monitor is configured as a handheld device including a color display, a plurality of user activated soft keys adjacent the color display and a plurality of icons provided on the color display proximate and corresponding to the soft keys. The color display has multiple modes that provide multiple parameter measurements of hemoglobin constituents that may include oxygen saturation displayed in a first color, carboxyhemoglobin displayed in a second color and methemoglobin displayed in a third color, among other parameters.

6. A patient monitor user interfacing method comprising:
-
providing a color display on a handheld patient monitoring device;
deriving a plurality of physiological parameter from a noninvasive multiple wavelength optical sensor attached to a patient tissue site and in communications with the handheld patient monitoring device;
presenting measurements of the physiological parameters on the color display as a selectable one of a plurality of views, wherein a first one of the views presents the physiological parameter measurements, a plethysmograph waveform and a signal quality waveform. - View Dependent Claims (7, 8, 9, 10)
