Section 2: Pump Setup and Programming
The Intermittent Delivery Mode (IDM) delivers a specified dose volume
over a specified duration. You may repeat the dose in a cycle of up to
96 hours. The KVO feature allows you to deliver a minimal amount of
medication between doses to maintain catheter patency. You may also
delay the start of dose delivery using the "Dose Starts In" feature.
