An oximetry device for monitoring blood oxygen saturation of a user includes a main body and a wrist strap coupled with the main body and adapted to removably secure the main body on a wrist of the user during operation of the device. The main body includes an oximeter sensor adapted to generate an output signal indicative of measured blood oxygen saturation, a controller in operative communication with the oximeter sensor and configured to determine a percentage blood oxygen saturation of the user as a function of the output signal generated by the oximeter sensor, and a display for presenting visual information generated by the controller to the user. The display includes a changeable backlighting color, the controller being configured to adjust a color of the display backlighting as a function of a measured blood oxygen saturation of the user.
