Method and Apparatus For Physiological Monitoring
First Claim
1. A method of representing or displaying blood pressure of a subject aurally, comprising the steps ofreceiving a signal representative of blood pressure information, andsynthesising an audio output from the signal,characterised in that the duration and pitch of the synthesised audio output are dependent on the blood pressure information.

Abstract
Blood pressure measurements are represented aurally. An audio synthesizer (15) receives a signal representative of blood pressure information, and synthesizes an audio output from the signal. Both the duration and pitch of the synthesized audio output are dependent on the value of the blood pressure information, according to a linear scale or a non-linear scale such as stepped scale. The blood pressure information includes at least one of arterial or pulmonary arterial systolic, diastolic and mean blood pressure measurements, and the audio output includes an earcon comprising a tone or sequence of tones, the tone(s) being representative of a respective type of blood pressure measurement. The earcon may also include one or more static or dynamic beacons.

18. Apparatus for representing a measured value of a physiological parameter of a subject aurally, comprising
sound synthesizer means adapted to receive a signal representative of the measured value of the physiological parameter and to synthesize an audio output from the signal, characterised in that the duration and pitch of synthesized audio output are dependent on the value of the measured physiological parameter.
