1 Kanmed BabyWarmer BW3 - Quick instruction
Leave the system constantly switched on - to be ready for instant use!
Refer to the Users manual whenever in doubt.
Filling the Water Mattress
•Fill the Water Mattress with warm water (about 350C). Fill to the Max H2O level mark +1- 2 cm. Check by holding
the Water Mattress upright. Add Kanmed Clean Water Tablets.
•Write the expiry date on the Water Mattress. (one year forward)
•There must be no air in the Water Mattress. Place the Water Mattress on a flat surface. Grip the open mattress hole
to lift the mattress and press all air bubbles out. Lower the hole and close it properly.
•Check the Water Mattress daily for leaks.
Using the Kanmed Gel Mattress
•If the Gel Mattress mode is selected, note that the heat transfer is less than that of water. Also note that the actual
Gel surface temperature may vary from the displayed temperature setting.
Inserting the Heating Pad and selected mattress into the Kanmed Baby Nest
•Place the selected mattress upside down on a flat surface. Insert the Heating Pad in the pocket with its printed text
towards the mattress. Turn the mattress over again.
•Insert the mattress with Heating Pad into the Nest pocket. Use the opening in the head end of the Nest to assist in
fitting the Nest to the mattress.
•You can use the BW3 without the Kanmed Baby Nest but it simplifies the positioning of the baby.
Preparing the bed
•Ensure that the bed has drain-holes in the bottom (when the Water Mattress is used).
•Place the BabyWarmer nest package on the bed mattress.
•Protect the Nest with a sheet that is soft but not thick.
Connecting the Control Unit
•Connect the mains power cable at the bottom of the Control Unit and hang it over the small hook.
•Connect the Heating Pad at the back of the Control Unit. Be gentle, and fit the connector the correct way. Tighten
the connector screws gently.
•Place and secure the Control Unit in a safe place where the display can be clearly seen.
•Press the start button on the front panel and observe that the self test performs correctly.
•During the self test, check that the correct mattress mode (H2O or GEL) is set. Change mode if required.
Placing the baby
•Only when the desired temperature is reached (green smiley-indication), should you place the baby on the
mattress.
•Position the lightly dressed baby (nappy, long arm T-shirt, bare legs (and a cap on very small ones)) on its back in
the Nest. Other positions are subject to approval from authorised staff and local protocols.
•Adjust the Nest size by pulling the string. Hide the string under the mattress.
•Cover the baby with suitable cover, such as 1-3 layers of soft cotton blankets.
Temperature setting
•All babies are individuals and their temperature must be controlled frequently until you are familiar with the baby’s
reaction to the set temperature. Overheating is often caused by covering the baby too much.
•When the Water Mattress is used, 370C- 37,50C is a good starting temperature for slightly hypothermic babies and
for babies weighing about 1000g.
•36.50C - 370C is the most common temperature for babies weighing more than 1200g
•As the baby’s weight increases, the temperature is primarily controlled by changing the number of blankets that
cover the baby and secondly by changing the set temperature.
•When the lightly dressed and covered baby is maintaining body temperature with a Water Mattress temperature of
about 35.5 - 360C, then the baby is probably ready for a standard cot that has no additional warming.
•If the Gel Mattress is being used, try setting the temperature to 37-380C in order to compensate for the heat loss in
the Gel Mattress. Otherwise the same operating instructions apply, but beware of the reduced warming efficiency of
the Gel Mattress. Connecting a skin type temp sensor to the unit may be helpful in obtaining the right temperature.
Maintenance
•Wash the re-usable Kanmed Nest at maximum 900C. Preferably 600C. Tumble dry it. Kanmed recommends changing
the Baby Nest once a year.
•Disinfect the surface of the Mattress, the Control Unit, Gel Mattress and the Heating Pad.
•Check the water level in the Water Mattress frequently and remove any air. Replace the Water Mattress once a
year.
•See the user’s manual for further maintenance instructions and periodical safety checks.

2 Safety Instructions
Please study this manual thoroughly and you will find the Kanmed BabyWarmer BW3 to be both safe and
easy to use.
Intended use
The intended use of the Kanmed BabyWarmer BW3 is to keep newborn and premature babies normo-
thermic. Kanmed BabyWarmer BW3 is designed for hospital use only.
It must be used according to the instructions in the manual and according to established clinical routines
and by qualified personnel.
Essential Performance
The automatic system supervision will safeguard any malfunction that may have influence on the performance of the
system. If used according to this instruction manual, and if the warning information is considered, no unacceptable
patient risks should occur. However, always monitor the patient's vital signs and adapt the use after the patient's actual
requirements.
Warning
•Proper Use. To ensure optimal performance and to prevent incorrect use, the user manual must be
read completely before the system is being used. Only use genuine Kanmed BabyWarmer parts
together with the BW3 control unit.
•System Malfunction. If the BabyWarmer BW3 self test does not perform correctly or the system
displays an alarm or error message, or the Control Unit has been dropped, received mechanical
damage etc., it must be examined by a qualified technician before being used. If it is suspected that
the BabyWarmer BW3 is not operating properly, immediately consult a qualified technician for advice
and do not use it.
•Never use the BabyWarmer BW3 without a Kanmed Water or Gel Mattress!
•Electrical Hazard The system must always be connected to a mains power outlet with proper
protective grounding. Always remove the mains power cable before cleaning the Control Unit.
•Body temperature. The temperature monitor is intended for added safety purposes only, please use
a dedicated hospital grade precision thermometer, and a method in accordance to hospital procedures
for precise measurements of the patient’s actual body temperature.
•Never place a baby face down on the Kanmed Mattresses or in the BabyWarmer Nest unless this is
ordered by responsible staff.
•A cold mattress, or a mattress which is cooling down due to the heating being switched off, will
decrease the body temperature of the baby. Likewise, a too warm mattress can induce fever.
•Trans dermal medications (patches) can increase drug delivery, resulting in possible harm to patient
when used with warming devices.
Caution
•Check the Water Mattress daily for leaks.
•Be aware that the acoustic alarm has a reduced sound level of 55dBA (adapted for use in silent
environments, e.g. a neonatal ward).
•Always fill the Water Mattress to the required level before the unit is brought into use. Preferably fill
with lukewarm water at around 350C.
•Replace the Water Mattress periodically as indicated on the Water Mattress (after about 12 months of
use).
•Don't fold or bend the Heating Pad sharply, don't pull the Heating Pad cable or use it for carrying the
Heating Pad.
•Make sure that the text side of the Heating Pad is facing the Mattress.
•Make sure that there are at least 2 drain holes in the bottom of the bed if using the Water Mattress.
•Make sure that the adjusting string is placed outside the Baby Nest to prevent it from interfering with
the baby.
•Check the temperature of the baby regularly. Check the mattress temperature regularly.
•Continue to use appropriate monitoring of vital signs.
•Before first use, please clean everything according to your standard hospital routines and to
instructions in the user manual. Always wash a new re-usable Baby Nest before first use.
•Please note that the control unit BW3 shall be placed standing on a flat surface, or mounted with the
front end up, having the display clearly visible.
•The BW3 may not be interfaced with any other electrical system. If this is done a new “system” is
created per definition, and the safety classification of the BW3 may be effected. Please be aware that
use of HF surgical instruments or similar devices may interfere with the BW3 and may require special
precautions regarding potential equalization etc.
•The Kanmed Gel Mattress may not be used without its integrated aluminium-plate.

2. Always use a Kanmed Water (H2O)
or Gel (//////) Mattress.
Never place a baby directly on
the Heating Pad!
3. The Heating Pad must be inserted in the
pocket under the Mattress.
(This is best done if the Mattress is placed
upside down on a flat surface).
The Water Mattress
When filled to the level mark a standard Water Mattress contains about 4.5 litres of water. Always add
Kanmed Clean Water Tablets when the Water Mattress is filled. One Tablet per litre of water. The water
level should be checked frequently and water must be added if required. Big air bubbles must be removed.
When used for the first time, please write the date of expiry in the box (one year into the future).

The Gel Mattress
A Kanmed Gel Mattress may be used as an alternative to the standard Water Mattress. Please observe that
when a Gel Mattress is used, the heating capacity of the Kanmed BabyWarmer system is reduced
(compared to water). The indicated temperature is an estimated temperature value and may differ from
actual spot temperature readings on the Gel Mattress surface. In GEL-mode there is a 2,0° C offset added
to the Heating Pad temperature (compared to the set temperature) to compensate for the lesser heat
conductivity of the Gel Mattress.

6 Mattress selection, Adjustments and Areas of use
Kanmed Water Mattress
Suitable for all babies until very little warming is needed.
The Water Mattress is superior in conducting warmth to the baby thereby ensuring optimal weight gain. It
should therefore be the first choice.
The warm soft Water Mattress has a calming and relaxing effect on the baby and ensures better sleep
quality. Its softness prevents skin damage and many customers reports that it helps to form a nice shape
of the babies head.
The Water Mattress is also a heat buffer and will only loose about 1,5°C per hour in case of power
interruption
Kanmed (special soft pebble surfaced) Gel Mattress
The Kanmed Gel Mattress is for new born or near full term babies in need of some additional warming.
The heat conduction is not as good as water. It is not as soft as the Water Mattress.
Therefore attention shall be paid to the baby’s temperature and to its weight gain.
Note: The Gel Mattress must not be used without the integrated aluminium plate. Only Kanmed Gel
Mattress will function with the BW3
Warning: If the Gel Mattress is covered with several layers of material, to make the bed softer, then the
heat transfer will be greatly reduced - which in turn may reduce the warming efficiency therefore probably
affecting the baby's weight gain.
Placing the baby
•Only when the desired set temperature is reached (indicated by a green smiley), you should place the
baby in the Nest.
•Position the lightly dressed baby (nappy, long arm T-shirt, bare legs and a cap on very small ones) on
its back (unless otherwise prescribed by responsible medical staff) in the Nest.
•Adjust the Nest size by pulling the string. Hide the cord under the mattress.
•Cover the baby with suitable cover, such as 1-3 layers of suitable blankets.

User Manual BW3-070/4
Page 16 of 28
Temperature setting
•All babies are individuals and their temperature must be controlled frequently until you are familiar
with the baby’s reaction to the set temperature. Overheating is often caused by covering the baby too
much.
•When the Water Mattress is used, 37-37,50C is a good starting temperature for slightly hypothermic
babies and for babies weighing about 1000g.
•36.50C - 370C is the most common temperature for babies weighing more than 1200g
•As the baby’s weight increases, the temperature is primarily controlled by changing the amount of
blankets that cover the baby and secondly by changing the set temperature.
•When the lightly dressed and covered baby is maintaining body temperature with a Water Mattress
temperature of about 35.5 - 360C, then the baby is most often ready for a standard cot that has no
warming.
•If the Gel Mattress is being used, try setting the temperature to 37-380C in order to compensate for
the heat loss in the Gel Mattress. Otherwise the same operating instructions apply, but beware of the
reduced warming efficiency of the Gel Mattress. Connecting a skin type temp sensor to the unit may be
helpful in obtaining the right temperature
Neonatal intensive care units, Level II units, Intermediate care units, Step down units, etc.
In the neonatal care the Kanmed BabyWarmer with the Water Mattress is used to ensure an optimal
warming of all babies, from 800 g and up 3000g or until the baby gets too warm. Optimal warming also
ensures optimal growth rate. Kanmed BabyWarmer can replace the incubator when the baby is mainly in
need of the warming. Vital signs monitoring, oxygen support or CPAP can easily be continued on the
Kanmed BabyWarmer and the Kanmed Baby Bed
The Kanmed BabyWarmer with Water Mattress can also be used inside an incubator to help obtain correct
and stable body temperature, especially in older single wall units and on “modern” units where the whole
top goes up.
NOTE : Using the Kanmed BabyWarmer inside an incubator is the sole responsibility of the hospital. The
function and temperature regulation of the Kanmed BabyWarmer is not influenced by the incubator.
Delivery Wards
Kanmed BW3 can be used to warm children that for different reasons have lost heat post delivery.
Kanmed BW3 is also perfect for keeping newborn babies warm until the mother is able to / wants to warm
the baby herself.
Try the Water Mattress for children in need of a soft warm support, for instance children suffering from
hydrocephalus, fractures, pain after delivery with a forceps or a suction device, colicky pains, etc.
In rooms with low temperatures the Kanmed BabyWarmer will help keeping the baby warm..
If only modest heating is needed then the Gel Mattress is and ideal alternative to the Water Mattress.
Maternity Wards
Low birth weight or premature babies that do not need all the resources of an intensive care department
but need support to stay warm can thanks to the Kanmed BW3 be kept with the mother in the ward.
Babies with a weight between 1800gram and 2500 gram, born around pregnancy week 35 - 38, are often
not capable of maintaining a normal body temperature during their first days after birth. The Kanmed
BabyWarmer keeps them at normal body temperature and assists them to stay with their mothers.
Unsettled, stressed and screaming babies can often find a soothing and relaxing environment on the warm
Water Mattress thereby relieving the staff and the parents. The Gel Mattress can also be used but be aware
of the limited warming capacity compared to the Water Mattress.
NIDCAP, Developmental Care and Kangaroo care
In these treatment modalities the sleeping, rest and positioning of the baby plays an essential role. The
warm soft Water Mattress resembles the warmth of a mother’s skin therefore making the Kanmed
BabyWarmer the ideal tool to ensure quality sleep.
Photo therapy
Kanmed BabyWarmer is well suited for Photo therapy using an overhead lamp, and especially for new blue
LED lights that does not radiate any heat. Using the Kanmed Gel Pad is a practical option if the warming
capacity is considered enough –otherwise choose the Water Mattress.
Transport of babies inside the hospital using the Water Mattress
If the child is normally covered and in a standard cot, the Water Mattress temperature will only drop about
1.50C per hour when the power is disconnected and under normal temperature conditions.
Please note: A Gel Mattress cools of much faster (>50C / h).

Temperature Check
To perform the temperature check a precision thermometer preferably with a skin type sensor is needed.
The built in temperature monitor with an YSI400 type sensor (having an specified accuracy better than
±0,2°C) may be used.
Note: In this procedure the standard type Kanmed Water Mattress must be used.
•Make up the bed as for normal use and place the temperature sensor in the centre on top of, and
fixed in direct contact with the Water Mattress (e.g. using a surgical tape or similar). Cover the sensor
with some insulating material. Check that there is no air in the Water Mattress.
•Set the temperature to 37 OC and allow the system to settle temperature in steady state (note, this
may take several hours).
•Check that the precision thermometer (or the built in temperature monitor) and the Control Unit
displays the same reading, allowed difference ± 0.7OC.
8 Alarm functions, indication and actions
Temperature monitor alerts
These alerts relates to the built in temperature monitor, and does not effect the function of the
BabyWarmer. The temperature monitor is only activated when an YSI400 compatible temperature sensor
is connected. If a temperature monitor alarm condition is detected, the alarm is activated, indicated on the
display by a flashing thermometer icon, audio signal and the yellow LED. After pressing the alarm button,
the alarm will be silenced for 2 minutes. If the alarm condition remains, the alarm will return.
Indication
Description / Operator action
(FLASHING)
High temperature. The measured sensor temperature is higher than the
set high alarm limit
Action:Check the settings and the patient's actual body temperature.
Remember that the Water Mattress cools slowly.
Temperature OK! (Normally displayed). The measured sensor
temperature is in between the High- and Low alarm limits.
(FLASHING)
Low temperature. The measured sensor temperature is lower than the
set low alarm limit.
Action:Check that the temperature sensor is properly applied to the
patient. Check that the BabyWarmer system is working in a correct way,
and that right temperature settings are used. If the sensor temperature is
rising, but not yet reached up to the Low alarm level, the indicator
indicates blue but not flashing (no alarm condition!).

Quick indications
Informative system messages only, the system will continue operation as normal. The colour of the face
icon depends on a combination of the mattress temperature and the YSI400 temperature sensor.
Indication
Description / Operator action
Excess heat / Slow cooling / High temp alarm. The mattress has a higher
temperature than the set value or the temperature monitor YSI400 sensor is
warmer than the Hi temp alarm level
Action:Will normally occur after the set value has been reduced from a higher
value. The settings should always be checked, and if found necessary, the patient
may be temporary removed (and cooled down).
Within limits! Set temperature has been reached and the temperature monitor is
within the alarm levels (if a sensor is connected). The system is ready for use
provided that a correct set temperature has been chosen.
Low heat / Slow heating / Low temp alarm. The mattress has not reached the
set temperature or the temperature monitor YSI400 sensor is colder than the Lo
temp alarm level (if a sensor is connected). Will normally occur when a cold start is
being performed.
Action:Check the temperature monitor sensor. All settings should be checked. If
a cold start has been performed, the patient should not be placed on the mattress
before the indication has turned green.
High mattress temperature. The calculated temperature is more than 0,8°C
warmer than the set value. The mattress temperature is displayed in the icon.
Within limits! The calculated temperature is within ±0,8°C of the set value.
Low mattress temperature. The calculated temperature is lower than 0,8°C
below the set value. The mattress temperature is displayed in the icon.
Medium priority errors and alarms
When a medium priority error is detected, the alarm is activated (error code on display, audio signal and
the error LED blinks yellow.). After pressing the alarm button, the unit will continue to operate normally for
2 minutes. If the error condition remains, the alarm will return.
