patient movement detection
The patient movement detection system can be set to alarm
when undesired movement of the patient occurs. The
sensitivity of the patient movement detection, relative to the
centre of the mattress platform, can be varied incrementally.
The controls for the patient movement detection system are
located on the foot end split side rails.

In Bed:

detection and increases the sensitivity of the system.
Patient movement detection threshold display:

shows the current system status and the selected sensitivity of
patient movement detection.
Egress:
this button activates/deactivates patient movement
detection and decreases the sensitivity of the system.
Operation
Before activating patient movement detection, make sure that:
• The patient’s weight has been measured and recorded.
• All additional items (e.g. accessories) have been
accounted for using the Auto Compensation function.
• The weighing system display is blank.
WARNING
The patient movement detection function should be checked
periodically for correct operation and before each new patient uses
the bed.
Mattresses that are not approved by Arjo should be validated by the
user to ensure correct operation with the
VariZone
system.
NOTE
Adjusting the mattress platform profile while patient movement detection is active
can trigger an alarm if patient movement detection is set to a high sensitivity.
