GUIDELINE FOR USE OF WATERLESS MILK WARMERS
The use of the waterless milk warmer is a method to gently warm milk to keep living, bioactive, and essential
components of stored human milk intact so that it remains as similar to fresh milk as possible.
Using a controlled method of warming/thawing is the best practice for preserving nutrient content and
preventing adverse effects on human milk and milk additives
Applicability:occurs within the Neonatal Intensive Care Unit (NICU).

Warming Procedure
Notes
1. Obtain milk from fridge and initiate warming
procedure as soon as possible
Fresh milk can be fed immediately to infant as it
is at body temperature
Prevention of additive degradation and to
secure nutrition viability ideal milk temperature
is 32-370
To ensure final temperature of milk after
warming remains between 32-370:
oTake milk from fridge and put
immediately into warmer
oMinimally handle milk after taking it out
of the fridge (e.g. do not leave on
counter or hold in hand)
o*NB –if left at room temperature or held
in hand this will quickly change the
starting temperature of the milk resulting
in warmer final temperature which may
be above 37 degrees.*
2. Press enter to confirm “warm” mode
The warmer is set to default to warm mode when
turned on and displayed in screen
3. Select the milk starting temperature:
Refrigerated, Room or Frozen and press

muted
8. When warming cycle is completed the
automatic holding cycle starts for up to 30

may fall below the designed range of the
device.
Ensure milk that is warmed to feed is at fridge
temperature to start.
Warmed product should be gently shaken to
avoid any hot spots before feeding infant
(direction of warm air blowing in device may
create temperature differences between top
and bottom of syringes)
