    Abstract: A patient monitor device includes one or more sensors which measure physiological parameters of a patient, a controller which controls an audio source to generate an audible tone and adjust the pitch or frequency of the audible tone to indicate the measured physiological parameter according to a mapping scheme, the audio source which generates the audible tone, and an audio output device which outputs the audible tone. The mapping scheme clamping a frequency of the audible tone after reaching a predetermined threshold.
