ALARMS
Alarms are activated by life-threatening, medical and technical events.
WARNING: Because of the large physiologic differences among individuals, we cannot
ensure that every life threatening event will trigger an alarm.
The PatientNet System cannot replace skilled nursing care and proper sur-
veillance. Any alarm or abnormal indication displayed by this system should
be reviewed by skilled clinical staff to determine if the appropriate diagnostic
procedure should be initiated.
This instrument may not produce alarms from some pacemaker patients who
experience cardiac arrhythmias. Maintain high-risk and pacemaker patients
under close surveillance.
WARNING: When using a bedside device with the instrument transceiver (DT-7000/7001),
the bedside device is the primary monitor and alarm source. Disabling
alarms on the bedside device is not safe clinical practice.
Alarm Detection
Alarms are detected according to patient type as follows:
Ambulatory patients: all alarms are detected at the Central Station.
Bedside monitored patients: alarms are detected at the bedside monitor, at the
Central Station, or both.
Ventilator patients: all alarms are processed at and by the ventilator unit; the
Central Station only displays the alarms received from the ventilator.
