ABSTRACT:
This invention provides apparatus for collecting parameter disturbance information from each connected apparatus which can disturb measuring vital signs, and broadcasting a message regarding the disturbance and a coordinating clock signal to all apparatus. Connected sensors susceptible to parameter disturbances identify them from the message and suppress their audible alarm during an interval given in the message. This eliminates false audible alarms caused by such disturbances. The disturbance interval can be extended for later disturbances unless it is a new source or disturbance type and the alarm is already suppressed. A brickwall timer limits the total maximum suppressed interval to a safe maximum. A recovery timer allows a sensor to recover from a parameter disturbance before responding to a subsequent one.
