Operation
Precautions
Reducing the internal temperature of the incubator
The cooling time is dependent on the design and can be
accelerated by:
- reducing the outside temperature (when possible)
- reducing the air-humidity setting.
The rate of cooling is not accelerated by:
- setting the air temperature to a lower value than is
actually required.
In urgent cases: open front door or hand ports. When
front door is opened, there must be continuous
supervision to make sure that the baby does not fall out.
Fire risk from oxygen
- No naked lights or smoking. Textiles, oil and plastics
can very easily catch fire and burn rapidly in an
oxygen-enriched atmosphere.
- Keep all fittings and seals in contact with oxygen free
of oil and grease.
- Open valves on 02 cylinders slowly.
- Do not use an incubator where there are flammable
anaesthetic gases or disinfection agents.
Risk of explosion.
- Do not use or keep flammable liquids, such as
alcohol, ether and acetone in the incubator.
- Do not use any electrical equipment inside the
incubator, except, that is, for equipment expressly
designed for use in areas where there is a risk of
explosion.
Physiological risks from oxygen
The air in the incubator should only be enriched with
oxygen when prescribed by a doctor. It is absolutely
essential that such oxygen enrichment is controlled
on the basis of the arterially-measured oxygen partial
pressure in the blood of the patient. This is the only
way of avoiding both hyperoxaemia (damage to the
eyes) and hypoxaemia (damage to the brain).
Temperature of breathing gas
During ventilation the breathing-gas hoses may become
too warm from the heated air circulating in the incubator.
The temperature of the breathing gas must be monitored.
Phototherapy in the incubator
Absorption of light through the baby's skin will supply
heat which may increase the baby's core temperature.
Therefore,
• Decrease temperature setting for incubator air by
about 2 °C 15 minutes before phototherapy.
• Decrease the set value for humidity.
• Reduce the room temperature to at least 3 °C below
the air temperature of the incubator.
This value applies for Drager 800/8000/4000
phototherapy units.
Other phototherapy units, particularly those without a
built-in fan, may cause even greater heating of the
incubator.
The core temperature of the baby must be monitored
with particular care during phototherapy.
The supply of fluids to the baby must be increased
e.g. by parenteral infusion, in order to compensate for
increased loss of water during phototherapy.
The phototherapy lamp and incubator canopy must
not be covered with cloths, aluminium foil, or other
materials, to boost the photo-therapeutic effect.
Risk of heat build-up. The incubator could not then be
adequately cooled with ambient air.
Danger of overheating the patient.
Preventing high noise levels
Noise levels that are too high for the patient may be
caused by:
- using head boxes to deliver pressurised gas,
- wear on the bearings of the fan motor,
- placing objects on the incubator canopy.
• Observe maintenance intervals, p. 42.
• Do not place anything on the incubator canopy.
Electrical safety
Use only electro-medical ancillary equipment which
complies with the IEC 601 -1, EN 60601-1 or DIN
VDE 0750, part 1, regulations.
