vPad-IV OPERATORS MANUAL
3.5 Fluids, Connections and Priming
3.5.1 Compatible Test Fluids
CAUTION: use only distilled water or clean drinking water with vPad-IV
Distilled water is the preferred test fluid for vPad-IV. Bottled drinking water may also be used provided the
water is demineralized and is not carbonated. Domestic water (i.e. "tap water") is useable as long as it is
clean, transparent and low in mineral content. Water processed with reverse osmosis is also acceptable.
Ideally the water should be de-gassed, or at minimum it should not contain visible air bubbles as such
bubbles may interfere with the flow measurement process. Accordingly, if water is drawn from the cold
faucet, it should be allowed to warm up to room temperature in an open container for a period of time so
that any dissolved air is released. Warming the water while gently stirring can help release trapped air.
Store the water at room temperature in a closed container to prevent contamination with dust, mould and
bacteria. Keep the storage container away from direct sunlight to avoid stimulation of algal growth.
DO NOT
use a medical solution such as physiological saline, lactated Ringer's injection, dextrose in water
(D5W or D50W), TPN solution and similar fluids with vPad-IV.
DO NOT
connect IV administration sets
or other tubing which may have been contaminated with such solutions to vPad-IV. Viscous fluids and
fluids which have a sticky or oily quality will prevent the flow sensor in vPad-IV from functioning correctly.
Damage to vPad-IV caused by use of an incompatible fluid, or an IV set which
has been contaminated by such fluid, is not covered under warranty.
Failure to observe these recommendations may result in inaccurate, intermittent or erratic measurements of
flow and volume. The effects of contamination with a soiled or incompatible fluid can be overcome in some
cases by cleaning the
glass flow sensor which is internal to the affected Module. See Sections 5.3 and 5.4 in
the maintenance chapter for further instructions.
