1. A medical patient monitor having an audio messaging system, the medical patient monitor comprising:
- a circuit which measures a physiological characteristic of a medical patient and produces a control signal in response to the physiological characteristic having a defined measured value;
an audio input device;
a loudspeaker; and
an audio processor having an input connected to the audio input device, an output electrically connected to the loudspeaker, a control input connected to the circuit for receiving the control signal, and a memory for storing an audio message related to the predefined event, the audio processor having a first mode in which a first signal received at the audio input is stored in the memory, and having a second mode in which the first signal is retrieved from the memory and used to generate a signal at the output in response to receiving the control signal.

Abstract
A patient monitor has a plurality of voice alarm messages stored in a memory. When the monitor detects an occurrence of an alarm condition, such as an usual physiological characteristic of the patient, a voice alarm message associated with that condition is played back through a loudspeaker. To enable the patient monitor to be used throughout the world, the end user is able to replace each of the prerecorded voice alarm messages. Thus the end user is able to store voice messages in the native language and dialect spoken where the monitor is used.

9. An audio messaging system for a medical monitor that measures a physiological characteristic of a medical patient and produces control signals in response to the physiological characteristic having different defined measured values, the audio messaging system comprising:
-
an audio input device;
a loudspeaker; and
an audio processor having an input connected to the audio input device, an output electrically connected to the loudspeaker, a control input for receiving the control signals and a memory which stores a plurality of prerecorded messages each of which is related to one of the different defined measured values, the audio processor having a first mode in which a user replaces at least one of the plurality of prerecorded messages with an audio signal received from the audio input device, and having a second mode which a message is retrieved from the memory and used to generate a signal at the output in response to receiving a particular one of the control signals from the patient monitor. - View Dependent Claims (10, 11, 12, 13)

14. A method of producing alarm messages from a medical monitor that measures a physiological characteristic of a patient, said method comprising steps of:
-
(a) a user of the medical monitor speaking an alarm message into a microphone that is connected to the medical monitor;
(b) recording the alarm message in a memory connected to the medical monitor;
(c) generating a control signal in response to the physiological characteristic having a defined measured value;
(d) in response to the control signal, retrieving the alarm message from the memory; and
(e) employing the retrieved alarm message to generate a signal that is applied to a loudspeaker that is electrically connected to the medical monitor. - View Dependent Claims (15, 16, 17, 18)
