Audible alarm enhancement for monitoring systems
First Claim
1. An alarm system comprising:
- a main processor and a first speaker in a computer-based monitoring system;
a sensor communicatively connected to said main processor for receiving input;
a second processor communicatively connected to said main processor for exchange of messages; and
a second speaker;
wherein;
A) said main processor sends periodic status messages to said second processor to notify said second processor that said main processor is running;
B) said second processor sends periodic status messages to said main processor to notify said main processor that said second processor is running;
C) said main processor will set an alarm condition to true based on input from said sensor according to a predetermined alarm logic;
D) said main processor will generate an audible alarm in said first speaker if said alarm condition is true;
E) said main processor will send a control message to said second processor to generate an audible alarm in said second speaker when said first speaker has been sounding for a predetermined time interval;
F) said second processor will generate an audible alarm in said second speaker if no status message is received within a predetermined time interval or if said control message is received from said main processor; and
G) said main processor will generate a visual or audible alarm if said status message from said second processor is not received within a predetermined time interval.

Abstract
An alarm system for a computer-based monitoring system such as a patient medical monitoring system is provided. The system comprises a main processor connected to a first speaker, a second processor communicatively connected to the main processor for exchange of messages; and a second speaker controlled by the second processor. A sensor is communicatively connected to the main processor of the monitoring system for receiving input such as physiologic input from a patient. The second speaker acts as a back-up in the event that the main processor fails to annunciate an alarm or an operator fails to respond to the first alarm within a predetermined time interval. An audible alarm is sounded when the main processor or second processor are not functioning normally.
