Intended Use

Babytherm® 8000 WB* is a unit for warming premature

babies, neonates and infants with a body weight of up to 5 kg.

The unit may be used in operating theatres, neonatal wards,

children’s wards and paediatric intensive care units.

The unit may be operated by clinical staff or by nursing staff

under the supervision of a doctor.

Babytherm 8000 WB provides heat through a heated gel

mattress.

Therapy and nursing uses

— Warming up, maintaining warmth and thermal stability with

mattress heating

— Cooling patients with high temperatures (temperature of

mattress below body temperature)

— Adjustable bed angle for head-up or head-down position

— Transitional bed for weaning infants from incubators

— Oxygen and nebuliser therapy (with appropriate

accessories)

Babytherm 8000 WB monitors and adjusts the temperature of

the heating plate to attain and maintain a preselected

temperature at the contact surface between the infant and the

mattress.

The heat supplied through the mattress is not sufficient on its

own for unclothed/uncovered infants/premature babies. An

additional radiant heater or a Babytherm 8000 OC should be

used.

Patient care

Precautions

● Never leave the patient unattended when the side panels

are down. Risk of infant falling out of the cot.

● When folding up the side panels, take care not to pinch any

parts of the patient’s body or any hoses or other articles,

e.g. bedding.

● Check that all 4 panels are closed and securely locked in

position: the yellow panel hardware should be visible above

the surface of the bed.

● The inner walls should be used with all patients, whether

the side panels are open or closed.

● With lively infants and/or older children, the 230 mm high

side panels should be used. Such patients should be kept

under very close observation.

Heat therapy

Two heating systems are available for keeping patients warm

and if necessary for warming up or cooling down patients:

— Mattress heater for operation, see page 16.

— Radiant heater with extra mobile stand (accessory).

Following the specific instructions for use.

Precautions

● Constantly monitor the core temperature of the patient.

● Adjust the temperature settings to the needs of the

patient.

● Increased heat is directed to the patient when the mattress

heater and radiant heater are operated in combined mode.

Follow the instructions on page 20 onwards for setting the

two heating systems, separately and in combination.

● When mattress heating is in use, the gel mattress must

be in place on the heated bed area.

● The gel mattress should only be used as a heating pad

with the Dräger Babytherm 8000. Do not use it with the

Dräger Babytherm 4200 or other warming beds with

heating plate temperatures over 40 oC – danger of

burns.

● Prevent contact with sharp objects, as these can damage

the gel mattress. Do not fold or kink the gel mattress.

To transport the gel mattress, roll it up.

● Always adhere to the gel mattress warming-up time.

Wait for about 1 hour before placing a patient in the

Babytherm, to allow the gel mattress to warm up sufficiently.

● Additional heat sources, such as phototherapy lamps or

radiant heaters, increase the heat directed to the patient

and should be taken into account. Avoid exposure to direct

sunlight.

Oxygen therapy

Precautions

The risks of the system are increased when oxygen is in

use.

— Avoid naked flame and lit cigarettes. Textiles, plastics and

oils are more easily ignited and burn with greater intensity

in an oxygen-rich atmosphere.

— Keep oxygen fittings and seals free of oil and grease.

— Open the valves slowly.

— Do not use Babytherm 8000 WB in the presence of

flammable anaesthetic gases or disinfectants.

— Do not use or store flammable liquids such as alcohol, ether

or acetone in the Babytherm 8000 WB.

— Do not use electrical appliances underneath the Babytherm

bed canopy, except for devices authorised and certified for

operation in explosion-hazard areas.

Physiological dangers of oxygen

Only enrich the oxygen concentration under the

instructions of a doctor and only in accordance with the

arterially measured oxygen partial pressure in the patient’s

blood. Otherwise there is a danger of hyperoxaemia (eye

damage) or hypoxaemia (brain damage).

During oxygen therapy, the oxygen concentration must be

constantly monitored, e.g. with Dräger Oxydig.

Increased noise level

Patients may suffer excessive noise when compressed gas is

administered using a hood.
