Operating Instructions Babytherm 8004/8010, 2. ed.

Precautions During Operation
WARNING !
Patient Temperature Monitoring
Check the baby´s core temperature and skin
condition at regular intervals and adjust tem-
perature setting to individual patient needs.
Core temperature of the baby must be
monitored particularly carefully during
phototherapy or while the radiant heater is
used in conjunction with mattress heater.
Skin temperature monitoring is no substitute
for core temperature checks since the two
parameters do not always closely correlate.
WARNING !
All accessories used must comply with
national safety standards for electromedical
equipment used in patient rooms
(e.g. IEC 601.1).
WARNING !
Continuous or intermittent audible alarms
require immediate operator attention to avert
or to prevent development of situations with
the possibility of patient injury.
WARNING !
When folding up surrounding panels, take
care not to pinch patient body parts, circuits,
or other items, such as sheets.
WARNING !
For lively and greater babies use side panels
of 23 cm height and additional inner panels.
Supervise the baby corresponding to its
liveliness.
WARNING !
Never leave patient unattended when
surrounding panels are down. Risk of patient
injury by infant falling out of the bassinet.
Precautions During Preparation
CAUTION !
Never route patient circuits or lines over top of
panels – they may get pinched when folding up
panels or when installing cover.
CAUTION !
Do not place any objects above or underneath
bassinet where they might be damaged when
height adjustments are made.
CAUTION !
Always verify that monitor shelves and other
accessories are securely attached.
Always observe the following load limits
per shelf: not to exceed 20 kg (44 lbs).
total load on both columns: max. 30 kg (66 lbs).
For items attached to column on swivel shelves,
do not exceed load of 5 kg on that column.
WARNING !
To maintain grounding integrity, connect only
to a "hospital grade" receptacle.
WARNING !
Always select correct mattress type for
intended mode of operation (see page 20).

Operating Instructions Babytherm 8004/8010, 2. ed.
CAUTION !
Always use circuits and patient lines with sufficient
length for secure connection at minimum and
maximum height.
CAUTION !
Always observe the load limit of 50 kg on the
electric height adjustment.

WARNING !
Fire Hazards from oxygen !
– No open flames or cigarettes !
Textiles, plastics, and oils readily ignite in
an oxygen enriched atmosphere and burn
with great intensity.
– Keep oxygen valves, connections, and seals
free from oil and grease.
– Open valves slowly
– Do not operate Babytherm in the presence
of flammable anesthetics or disinfectants
– Do not use or store flammable liquids such
as alcohol, ether, or acetone inside the
Babytherm bassinet.
– Do not use electrical equipment inside
hood with the exception of devices
approved for use in explosive environments.
WARNING !
Always operate phototherapy lights in combi-
nation with radiant heater. Otherwise risk of
hypothermia for the undressed infant.
Core temperature of the baby must be
monitored particularly carefully during
phototherapy because of the additional
transfer of thermal energy to the patient.
WARNING !
Do not use skin temperature control for
infants with a high temperature. Their skin
temperature is significantly higher than normal
so that controlling skin temperature would lead
to hypothermia. We recommend to set heater
output manually when caring for patients with
such conditions (see page 28).
WARNING !
Skin temperature control must not be used
with babies in thermic shock. Because of
reduced peripheral blood flow the skin
temperature of these babies occasionally lies
well below the core body temperature. Using
a skin temperature control system could lead
to overheating. We recommend to set heater
output manually when caring for patients with
such conditions (see page 28).
WARNING !
Do not put any medications or infusion
solutions in the heated area.
WARNING !
Never leave baby unattended while radiant
warmer is in operation!
Measure core temperature at regular intervals!
WARNING !
Do not use flammable detergents, or medi-
cations while radiant heater is in operation.
Fire hazard!
WARNING !
Do not touch top of radiant heater or
protective screen.
Danger of burn injuries!
WARNING !
Mattress Heater
(Babytherm 8010 only)
When mattress heating is used, the gel mat-
tress must be placed directly on the heated
tray surface.
The Dräger gel mattress (part no. 2M 20 827)
must not be used in any bassinets other than
the Babytherm. Heater plate temperatures
above 40 °C (104 °F) implicate the danger of
patient burns! Use of a gel mattress with
unheated bassinets will result in uncontrolled
patient cooling.
Always take into account warm-up time of the
mattress (approximately 1 hour) before
placing a patient in the bassinet.
Do not switch off Babytherm while a baby is
lying on the gel mattress as this will result in
uncontrolled cooling of patient .
Important Safety Information

Operating Instructions Babytherm 8004/8010, 2. ed.

CAUTION !
Do not place any objects above or underneath
bassinet where they might be damaged when
height adjustments are made.
CAUTION !
Remove from mattress all objects with sharp
edges. The gel mattress could be damaged!
Do not fold gel mattress!
WARNING !
Check the baby´s core temperature at regular
intervals. Phototherapy increases heat
transfer to patient.
Measure patient's bilirubin level at regular
intervals
WARNING !
Always consider differentiated diagnosis for
patient so life sustaining measures are not
delayed.
WARNING !
Always use patient eye protection when using
phototherapy.
WARNING !
Use temperature settings in the lower exten-
ded temperature range only on the order of a
physician. Watch patient particularly carefully!
WARNING !
Always warm up mattress before placing
patient.
Do not switch off Babytherm while a baby is
lying on the gel mattress as this will result in
uncontrolled cooling of patient.
WARNING !
When using skin temperature control mode,
check infant skin condition at regular intervals
and verify that skin temperature probe is
securely attached. A detached probe will
measure air temperature and the baby might
become overheated.
WARNING !
Never use skin temperature probes for rectally
measuring core temperature !
Specifically, never use skin temperature probe
rectally for skin temperature control as this
would measure and use core instead of skin
temperature for control.
WARNING !
The sensor probe must never be placed under
the baby. It would be measuring and attemp-
ting to control core temperature rather than
skin temperature.
WARNING !
Always verify that sensor probe is specified
and approved for use with Dräger Babytherm
Radiant Warmer 8004/8010.
WARNING !
Physiological risks of oxygen !
– Oxygen therapy only on the order of a
physician
– Elevated oxygen concentrations must be
selected on the basis of arterially measured
oxygen partial pressure in the patient's
blood. Otherwise risk of hyperoxemia (eye
injuries with consequential blindness) or
hypoxemia (brain injuries).
– Monitor oxygen concentration at all times
during oxygen therapy.

Mattress heating
The Babytherm 8004/8010 features a mattress heating
system that uses conductive heat transfer to warm up
patients and to keep them warm.The system consists
of a gel mattress, an aluminum heating plate and an
electronic control and monitoring unit.
The gel mattress is made of a gel material with
excellent heat conducting properties, which won't dis-
locate even when the bed is tilted. The gel is enclosed
by a soft, skin compatible film.
The mattress molds itself to the body contours of the
patient lying on it, resulting in a large contact surface, a
property facilitating heat conduction to the patient and
avoiding pressure points (anti-decubitus effect). A cold
gel mattress, on the other hand, dissipates a patient's
thermal energy. The gel material has an excellent capa-
city for storing heat. When the power supply is discon-
nected (e.g. during a transport within the hospital), the
patient is kept warm for approximately 15 minutes if
sufficiently insulated (blanket, cover).
The aluminum heating plate consists of a 6 mm
(1/4 inch) thick aluminum plate and a heater element
attached below. It distributes heat evenly over the
entire bed area.
The mattress heater membrane keypad with its buttons
and display is located on the right-hand side of the
controller unit.
Mattress temperature is controlled according to the set
value entered. It adjusts in such a way that the set
temperature is reached (but not exceeded) in those
areas where the patient is in contact with the mattress.
System monitoring includes check routines and alarm
features.
Configuration mode
Configuration mode is a special operational mode of
the Babytherm 8004/8010 controller. In this mode,
information regarding software version and error log
cna be polled. The device can also be programmed
with user specific settings of skin temperature alarm
threshold, volume of audible alarms, as well as
language and contrast of the alphanumeric display. It
also serves to test the built-in nurse call and keys of the
operating panel.
Description of System Components
Babytherm consists of
– a mobile chassis with the attached infant bed
– a controller unit with operating panel
– a radiant heater, and
– a mattress heating system (Babytherm 8010 only)
Controller unit
The controller unit is located below the radiant warmer
between the two support columns at the head end of
the bed. The panel contains a membrane keypad and
display area. Integrated into the alphanumeric display
(2 x 40 characters) is a user guide for easier operation.
Radiant heater
The radiant warmer combines two infrared ceramic
heaters and 2 lights for illuminating the bed surface.
An integrated phototherapy light is optional.
The work light provides two settings, for daytime and
for nighttime lighting. The well balanced color spectrum
of the lamps used makes it easier to recognize diag-
nostically significant skin color nuances.
The radiant warmer can be operated in manual control
mode or skin temperature control mode.
"Manual" control mode provides fixed heater output
level settings from 1 through 10.
"Skin control" controls skin temperature according to a
preset value. Heater output is then automatically
controlled to patient needs.
Both modes of operation are monitored with check
routines and alarm schemes.
ThermoMonitoring
ThermoMonitoring is made possible with a secondary
skin temperature sensor. Skin temperatures taken
close to the body core and at the periphery (tummy-toe
temperature monitoring) are displayed on the controller
unit. They can be graphically represented on a PC via
optional serial interface (RS 232), using Dräger's
ThermoViewsoftware, improving diagnostic
possibilities.
Theory of Operation
Description of System Components

Operating Instructions Babytherm 8004/8010, 2. ed.

Phototherapy (available option)
Light from the halogen lamps contributes to photo-
chemical breakdown of bilirubin in the skin.
Dräger halogen lights emit very effectively at wave-
lengths around 460 nm without the blue light often
associated with phototherapy. They therefore provide
for good skin color representation.
Phototherapy is switched on the main controller panel.
Modes of heater operation Babytherm 8004
– Operation of radiant heater with preset heater output:
Heater output is controlled in "manual" mode and
therapy is time-limited for higher heater output
settings.
– Operation of radiant heater in "skin control" mode:
Skin temperature is monitored and controlled.
Modes of heater operation Babytherm 8010
– Operation of radiant heater with preset heater output:
Heater output is controlled in "manual" mode and
therapy time-limited for higher heater output settings.
– Operation of radiant heater in "skin control" mode:
Skin temperature is monitored and controlled.
– Mattress heater, independent of radiant heater:
Temperature of heating surface monitored and
controlled to maintain a preset temperature in the
contact area between infant and mattress.

Operating Instructions Babytherm 8004/8010, 2. ed.

Alarm System
The Babytherm controller distinguishes three levels of
alarms.
High potential for patient risk
a continuous audible alarm (enunciator) that cannot be
silenced, for:
– device malfunction,
– power failure
an alarm tone sequence (loudspeaker) that can be
silenced in combination with flashing red LED, for:
– mattress heater sensor failure,
– mattress heater exceeding temperature limits,
– skin temperature sensor not connected during
skin control,
– sensor failure of tummy or toe skin temperature
sensor.
Medium potential for patient risk
an alarm tone sequence (can be silenced ) in
combination with flashing yellow LED, for:
– deviation between set and measured value for
skin or mattress temperature exceeding tolerance,
– 15-minute alarm (as a reminder to check core
temperature during manual mode with heater
levels higher than 3).
Low potential for patient risk
Display messages for:
– measured values out of measuring range,
– low battery voltage.
Any alarm that has not been acknowledged is indicated
by flashing red central alarm light on the radiant heater
unit.
The display shows a specific message for the alarm
activated.
NOTE: A new alarm being activated will always override
audible alarm silencing.
Central Alarm
1Red light on radiant heater starts flashing simul-
taneously with any audible alarms.
Acknowledging the alarm will switch light off.
