Abstract: An example method, apparatus, and pulse oximeter device for determining a blood oxygen saturation value in a subject are provided. The example apparatus may include a light source configured to emit monochrome light of a single emitted wavelength. The light source may be positioned to direct the monochrome light at a portion of a subject. The example apparatus may further include a light sensing diode configured to receive an unabsorbed portion of the monochrome light. The apparatus may also include a controller configured to determine a blood oxygen saturation value based on one or more characteristics of the unabsorbed portion of the monochrome light comprising light of the single emitted wavelength.
