Abstract
Systems and methods for generating a sonification output for presenting information about physiological parameters such as oxygen saturation and heart rate parameters in discrete auditory events. In a preferred embodiment, each event comprises two sounds. The first is a reference sound that indicates the desired target state for the two parameters and the second indicates the actual state. Heart rate is preferably represented by amplitude modulation. Oxygen saturation is preferably represented by a timbral manipulation.
