Operation Precautions
Operation
Precautions
Before each use, check that the unit is ready for operation (see page 26).
Make sure that all hoses and cables are routed correctly and safely without obstruction! Otherwise: Risk of extubation! Danger of disconnection!
Lively patients must be observed with particular care.
When the canopy, front flap, hand ports are opened or when the bed has been pulled out or when the tubing grommets are removed, the patient must be observed constantly to make sure that he or she cannot fall out of the incubator.
Do not lean or apply weight on the bed when it has been pulled out. Maximum load 5 kg
Do not use the X-ray drawer as writing support or bed for the patient.
Allow time for the incubator to warm up before use (page 105).
Additional external heat sources, such as sunlight, heat lamps, spotlamps and electric cushions should be avoided! They cause the temperature inside the incubator to rise in an uncontrolled manner.
The baby’s core temperature must be regularly monitored with an independent thermometer.
The conclusions to be drawn from the measured skin temperature are the responsibility of the attending physicians.
Skin temperature control mode must not be used on babies who are in shock or who have a high temperature!
Skin temperature control mode must not be used on twins, since the Caleo
®
controls only the temperature for one baby. Risk of hypothermia or overheating! For twins, the air temperature control mode must be used.
Make sure that you do not confuse the positions for the skin temperature sensors. Skin temperature control is regulated by the yellow skin temperature sensor (T1). If this sensor is stuck to the wrong part of the body, the patient may be excessively warmed!
Do not place any cloths over the hot air duct. The temperature control system would be disrupted, causing a risk of burning if the air from the hot air duct is channelled directly to the patient.
When treating larger babies, the higher heater output may
®
cause the air temperature in the Caleo
incubator to rise. In
this case the double wall should be removed.
The room temperature must be at least 3 oC lower than the air temperature in the Caleo® incubator.
When treating twins, pay attention to the risk of cross­infection!
Fire hazard from supply of O2
— No naked lights or smoking. Textiles, oil and plastics can
very easily catch fire and burn rapidly in an O2 enriched atmosphere!
— All fittings and seals in contact with oxygen must be kept
free of oil and grease! — Open valves on O2 cylinders slowly! — Do not use Caleo® in the presence of flammable
anaesthetic gases or disinfecting agents. Risk of explosion! — Do not use or keep flammable liquids, such as alcohol,
ether or acetone, in Caleo®! — Do not use any electrical equipment in the patient capsule,
unless this equipment is expressly designed for use in
explosion-hazard areas.
Note the physiological risks from O2.
During O2 therapy, monitor the O2 concentration with a separate O2 monitor.
The air in the incubator may only be enriched with O2 when prescribed by a doctor.
O2 enrichment must be controlled on the basis of the arterially measured oxygen partial pressure in the patient’s blood. Otherwise, there is a danger of hyperoxaemia (damage to the eyes) or hypoxaemia (brain damage).
Medicaments and similar substances must not be atomised in the patient capsule. Correct functioning of the incubator may be impaired by the precipitation of atomised substances.
Do not cover the sensor unit and do not hang anything from the slits in the sensor unit. Keep the slits of the sensor unit free of impurities.
O
In the event of a power failure, the C
2 level in the patient
capsule may rise due to an insufficient supply of fresh air. Pay attention to the risk of C
O
2 poisoning!
The central alarm light can be deactivated (see page 122). Always check the alarm LEDs on the control panel and the associated alarm beep signals.
34
Operation
Precautions
Front flaps
When closing the front flaps, make sure that the patient is not lying in the closing path.
The front flaps are not properly shut until the red latches are no longer visible.
When opening and closing the front flaps, make sure that the hoses and cables are not caught in the moving double wall!
Side flaps
When opening and closing the side flaps, make sure that the hoses and cables are routed safely and clear of any obstructions!
The side flaps are not properly shut until the red latches are no longer visible.
Canopy
The canopy must not be used as a shelf for laying clothing, instruments etc. Before moving the canopy, make sure that nothing has been laid on top of it. When fitting and removing the canopy cover hold it firmly in your hand. The canopy installation catch must engage correctly. Do not lift the canopy when engaged. Do not tilt the canopy forwards. When closed, make sure that the canopy cover sits firmly in place!
Double wall
To fit and remove the double wall, remove the canopy from
®
Caleo
.
Tilting/height adjustment
Ensure that the cables and hoses are routed correctly and safely without obstruction. Hoses and/or cables risk being trapped when tilting the Caleo® and when opening and closing the front flap.
When using Phototherapy
Absorption of light through the baby’s skin will supply heat, which may increase the baby’s core temperature.
For this reason: — Roughly 15 minutes before starting phototherapy,
decrease the air temperature setting for the incubator air
by about 2 oC. — Decrease the set value for humidity. — Room temperature must be at least 3 oC lower than the air
temperature inCaleo®.
This value applies to Dräger Type 4000 phototherapy units.
When using other phototherapy units, especially units
without a built-in fan, the temperature in the Caleo®
incubator may rise even more sharply. — Phototherapy may only be used with a stand!
The core temperature of the baby must be monitored with particular care during phototherapy!
The supply of fluid to the baby must be increased, e.g. by parentral infusion, to compensate for the increased loss of water during phototherapy.
The phototherapy lamp and Caleo® canopy must not be covered with cloths, aluminium foil or other materials in
order to boost the phototherapeutic effect – risk of heat build-up, as the incubator cannot be adequately cooled with ambient air.
Danger of overheating the patient.
In-house transport
An even floor surface must be ensured when moving the Caleo® incubator. The incubator must not be used outside the hospital building, as the castors may be damaged or dislodged.
The Caleo® may only be moved when empty.
Kangaroo mode
The patient’s core temperature must be monitored constantly, because it is outside the controlled climate. Particular attention must be paid to critical patients vital parameters.
High noise levels
Excessive noise levels that can disturb the patient may be caused by:
— using O
2 head boxes and delivering pressurised gases,
— wear on the bearings of the fan motor, — placing objects on the canopy.
Observe the specified maintenance intervals – see
page 94.
Cleaning mode may only be used when Caleo® is empty. After use, allow Caleo® to cool down before dismantling.
Risk of burning when touching the heater!
35
Operation Precautions
Electrical safety
Do not use multiway adapters to connect the power supply of the Caleo
®
!
The patient leakage current may rise above the permitted limits if the protective earth conductor fails while equipment is connected to the socket strip. In such cases, the risk of electric shock cannot be excluded.
Only use electromedical ancillary equipment conforming to IEC / EN 60601-1.
When using the integrated socket strip: take into account the total leakage current and total current consumption! See "Technical Data" on page 104.
®
Caleo
does not monitor the power supply to external devices.
Mobile telephones must not be used within 10 metres of the incubator. Mobile telephones can interfere with the functioning of electromedical equipment and therefore endanger the patient!
* Dräger medical equipment conforms to the interference immunity
*
requirements laid down in product-specific standards or in EN 60601-1-2 (IEC 60601-1-2). However, depending on the design of mobile phone and the application situation, field strengths exceeding the values laid down in the specified standards may be generated in the immediate vicinity of mobile phones, thereby causing interference and malfunctions.

Connect the temperature sensors for measuring the skin temperature and peripheral temperature:
Plug the yellow skin temperature connector into the yellow
socket on the sensor unit (skin temperature, T1). When using skin temperature control, the control functions refer to this sensor.
Plug the connector of the white peripheral temperature
sensor into the white socket on the sensor unit (peripheral temperature, or skin temperature of the twin in the case of air temperature control mode, T2).
Route the sensor cable through one of the flexible tubing
grommets.
Remove the protective foil from the adhesive pad and place
the skin temperature sensor on the pad.
Using the adhesive pad, attach the sensor tip to the
appropriate part of the baby’s skin.

Positioning the skin temperature sensor (yellow): If the baby is lying on his/her back:
Attach the yellow sensor to the abdomen, near the liver.
If the baby is lying on his/her belly:
Attach the yellow sensor to the back, preferably near the
kidneys.
Positioning the peripheral temperature sensor (white):
Attach the white sensor to the extremities, preferably the
foot or arm.
Do not use the skin temperature sensor (yellow) or peripheral temperature sensor (white) to measure rectal temperature!
Regularly check that the skin temperature sensor is correctly attached to the patient’s skin. If the skin temperature sensor has fallen off, it will measure the air temperature, resulting in possible overheating of the patient
(although the air temperature would not rise above 39 oC).
When a skin temperature sensor is attached but "air temperature control" is activated, the measured skin temperature is displayed. However, in this case, the temperature is not controlled as a function of skin temperature!

Changing over between air/skin temperature control
Do not use skin temperature control mode on babies in shock, as their skin temperature is much lower than normal. Skin temperature control would increase the air temperature by too much and would endanger the patient. Use air temperature control – see page 38.
Do not use skin temperature control mode on babies with a high temperature, as their skin temperature is much higher than normal. The control function would overcool the incubator, resulting in the risk of hypothermia.
Do not use skin temperature control mode on twins, because Caleo® only controls the temperature for one baby. Danger of hypothermia or overheating!

Operation
Using skin temperature control
Make sure that you do not confuse the positions for the skin temperature sensors. Skin temperature control is regulated by the yellow skin temperature sensor (T1). If this sensor is stuck to the wrong part of the body, the patient may be excessively warmed.
Do not attach the sensor under the baby, because otherwise the core temperature, not the skin temperature, will be meas­ured and used as control parameter!
The baby’s core temperature must be measured
regularly with an independent thermometer!
Do not leave the canopy open for any length of time, because the air temperature in Caleo® will drop!

C after 1 hour).
Disinfecting/cleaning/sterilising
Use surface disinfectants for disinfecting. For reasons of material compatibility, use disinfectants based on — aldehydes — quaternary ammonium compounds.
Due to the chemical composition and direct effects on material compatibility, the following products are only suitable to a limited extent: — Halogen-releasing compounds — Strong organic acids —O2 releasing compounds.
Use only cleaning agent in autoclaves and other cleaning and disinfecting machines. Do not use any alkaline or chlorine releasing disinfectants, due to the risk of corrosion. As a general rule, the manufacturer's recommendations must be taken into account when choosing a cleaning agent. Liability for the specified use and for any material damage that may be caused by the product rests with the manufacturer.
Do not use any disinfectants or cleaning agents containing alcohol.
We recommend the use of disinfectants based on the current DGHM list (DGHM: German Society for Hygiene and Microbiology). The DGHM list (published by mhp Verlag GmbH, Wiesbaden) also gives the composition of each disinfectant. For countries where the DGHM list is not familiar, we recommend the types of disinfectant specified above.
