Refer to Table 6 - 1 for description on how the Arm Lights function while armed, injecting,
and/or during a hold.
NOTE:
If a Reminder is set, the operator is provided a communication once the Reminder elapsed
time equals the setting. If a test inject phase is programmed, the Reminder elapsed time
begins with the start of the first phase after the test inject.
NOTE:
The Reminder communication is removed when either the operator acknowledges the
communication or another communication is activated.
NOTE:
Test Injection - an injection phase followed by a hold phase. After the injection phase, the
system holds the injection until the operator presses Start/Hold on the injector head,
workstation, or handswitch to resume the protocol.
Vessel Hazard - Serious patient injury may result.
• Follow institutional extravasation minimizing techniques.
• A small volume test injection may be utilized to confirm venous access.
• It is recommended that the operator stay by the patient's side at the beginning of the
injection and to instruct the patient to communicate immediately any pain or change in
feeling during the injection.
• Check for extravasation of contrast or saline during injection.
• If an extravasation is detected, stop the injection and refer to respective facility policy
regarding treatment.
