Abstract

The present invention provides methods and devices for monitoring physiological data such that a health care provider is able to effectively monitor a patient's health status, including, for example, blood flow characteristics, without having to maintain constant visual contact. In one embodiment of the present invention, a physiological data monitoring system measures at least one physiological characteristic wherein the physiological data monitoring system comprises a sensor unit and a monitoring unit in data communication with the sensor unit. The monitoring unit has a sonification module that comprises one programmable sound generator module to produce a plurality of signals indicative of a physiological parameter and a memory module for storing a plurality of control parameters for managing the programmable sound generator module, wherein the plurality of signals produced have a plurality of frequencies modified in accordance with at least one physiological data value. More specifically, the present invention provides a pulse oximetry sonification system that generates fixed frequency singular and/or combined amplitude-adjusted dual audio tones corresponding to predetermined transition and/or intermediate points over a range of SpO2 measurements.
