Purpose
The purpose of this test is to check the leakage of current from the Warmer into saline. As IV fluids are generally conductive, a fluid warmer is considered to
be electrically connected to the patient similar to an ECG lead; therefore, the leakage needs to be tested. The setup for this procedure is described below.
Procedure
1. Leave the cap on the female end of the Disposable Cartridge.
2. Put an extension set on the male end.
3. Insert a piece of wire into the extension set tubing.
4. Fill the Disposable Cartridge and extension set tubing with saline. Note: It doesn't matter which way the wire is inserted into the tubing, just be certain
that the wire is in contact with the fluid.
5. Next, put a non-venting cap on the open end of the extension set.
6. Place the Disposable Cartridge setup in the Warmer.
7. Connect the ECG lead from the leakage tester to the wire inserted into the extension set tubing.
8. Perform the ECG lead leakage test.
