Preparing the Pump and IV Sets

Operator’s Manual
Secondary Infusion Setup
If the infusion is to include both a primary and a secondary bag and IV sets, follow these steps to
set up the bags and the IV sets.
NOTE:
The SIGMA Spectrum Infusion Pump does not infuse a primary and secondary infusion
at the same time.
To prepare the Pump for a secondary infusion:
1. Prepare primary and secondary bags and IV sets.
WARNING
Air Bubbles.
Failure to prime/remove all air bubbles from backcheck valves in
primary sets may cause the valve to malfunction, resulting in
secondary fluid flow back into the primary container.
CAUTION
Upstream Backcheck Valve Use
When connecting a secondary, ensure the primary administration set
contains an upstream backcheck valve.
2. Use a primary set with an upper Y injection site and backcheck valve.
3. Ensure the roller clamp on the secondary IV set is closed.
4. Connect the secondary set to the primary set’s upper Y injection site. Lower the primary bag
by fully extending the hanger approximately 50.8 cm (20 in) below the secondary bag. This
provides the secondary bag with a gravity advantage. It also causes the primary set’s
backcheck valve to close.
NOTE:
Secondary bag height must be 61 cm (24 in) from the top of the secondary bag to
the center of the Pump.
5. Confirm proper vent position, if applicable.
6. To program the secondary infusion, see “Secondary Infusion” on page 58.
