6. Alarms
6.1 Introduction
The ViSi Mobile Monitoring System provides a comprehensive alarm system that alarms on changes to the
patient’s physiologic status (alarms) and technical alarms (alerts).
The system provides default alarm limits for physiological alarms. The clinician can manually manage the
alarm limits for each patient to provide individualized care.
Technical alarms (alerts) are provided to notify the clinician of situations that may impede the ability to
monitor your patient.
6.1.1 System Alarm Management
During the installation of the ViSi Mobile Monitoring System, alarm configurations may be modified to
conform to the alarm policies set by the clinical care unit.
General Alarm Management Rules
The following general alarm management rules pertain to the ViSi Mobile Monitoring System:
• All ViSi Mobile Monitoring System alarms conform to IEC 60601-1-8.
• Alarms and alerts originate from the ViSi Mobile Monitor (worn by the patient).
• Silencing/acknowledging a patient’s alarm or alert suspends the audio tones for up to 2 minutes.
When a new alarm/alert occurs during the 2 minute silenced/acknowledged period, the new alarm/
alert will be immediately annunciated.
Note: When the clinician silences/acknowledges an alarm/alert, all active alarms/alerts in progress
will also be silenced/acknowledged for the 2 minutes. The clinician does not need to silence/
acknowledge each alarm/alert individually.
• Alarm annunciation may be turned off for an indefinite period of time. This disables the
annunciation of alarms and alerts on both the ViSi Mobile Monitor and the Remote Viewer for the
“off” duration. Turning the alarms off must be done directly from the ViSi Mobile Monitor (worn
by the patient), however, alarms may be turned back on from either the ViSi Mobile Monitor or the
Remote Viewer.
• Alarm annunciation may be paused for 2 minutes. This disables the annunciation of alarms and
alerts on both the ViSi Mobile Monitor (worn by the patient) and the Remote Viewer for the
paused duration. Pausing the alarms must be done directly from the ViSi Mobile Monitor (worn by
