AWarnings
Operator Safety
Before using the Ohmeda Infant Warmer System, read this entire
manual. Attempting to use this device without a thorough understand-
ing of its operation may result in patient or user injury. This device
should only be operated by personnel trained in its operation and under
the direction of qualified medical personnel familiar with the risks and
benefits of this type of device.
Overloading the shelves can affect the stability of the unit. Limit the load
to 20 lbs. (9 kg) per instrument shelf, mounted to a single upright, and
50 lbs. (23 kg) per monitor shelf, mounted between the uprights.
Limit the load of accessories to 50 pounds (23 kg) per side on the Warmer
to ensure stability. Accessories should not be mounted more than
56 inches (142 cm) above the floor. For models 3000 and 3500, limit the
load of accessories to 20 pounds (9 kg) maximum per side mounted no
more than 44 inches (112 cm) above the floor.
Limit the load placed on the x-ray cassette tray to 5 lbs (2.2 kg) to avoid a
tipping hazard.
Overloading the drawers can affect the stability of the unit. Limit the load
to 10 lbs. (4.6 kg) per drawer.
Do not use the Warmer in the presence of flammable anesthetics; a
possible explosion hazard exists under these conditions.
Do not touch the protective grill under the radiant heater or the top of the
heater assembly. These surfaces may be hot and a burn could result.
Due to the increased height of units with the ECMO option installed, a
tipping hazard may exist if tip loading occurs. Limit the total accessory
load to 50 lbs. (23 kg), no more than 25 lbs (11 kg) per side.
Use caution when rotating the cabinet to avoid damage to the drawers or
possible injury. Always ensure the drawers are fully closed before rotating
the cabinet.
Disconnect power to the Warmer and allow the heater rod to cool before
cleaning to avoid the possibility of a burn.
Never oil or grease oxygen equipment. Oils and grease oxidize readily,
and in the presence of oxygen, will burn violently. Vat-Kote is the only
oxygen service lubricant recommended (Ohmeda Stock No. 6700-0092-
200) if the use of a lubricant is specified.
Disconnect the Warmer power cord and allow the unit to cool before
replacing the alarm or observation lights.
On elevating models, check for proper clearance above the Warmer and
below the bed surface before raising or lowering the bed.
Enclosing the heater assembly inside a cabinet may prevent proper
ventilation and may create a fire hazard. If the heater is enclosed in a
cabinet, it must be equipped with a power cut-off device that prevents
operation while the cabinet is closed.

& 5 cm)will result in incorrect operation and may affect the patient’s
condition.
Do not place any accessories or any other objects directly over the bed
surface. This may block radiant heat and lead to cooling of the infant.
Do not place items on top of the heater assembly. Items placed on top of
the heater assembly can fall and injure the patient, prevent adequate
ventilation of the heater assembly, and may pose a fire hazard.
Do not perform the Checkout Procedures (Mechanical and Control Unit)
while a patient occupies the Warmer.
Complete the “Checkout Procedures” section of this manual before
putting the unit into operation. If the warmer fails any portion of the
checkout procedures it must be removed from use and repaired.
Regularly inspect the bed side panel latching mechanism, and the bed-
side locking mechanism on the model 3500, to ensure proper operation.
In the service position the strength of the wall mounted unit hinge
bracket is reduced. Never place a patient in the bed when the heater is in
the service position. Never leave the unit unattended in the service
position or with a pin removed.
Check for proper clearance above the Warmer and below the bed surface
before raising or lowering the bed.
Inspect all patient connected tubes or wires before and after moving or
tilting the bed. Tilting or moving the warmer bed up or down can pull on
tubing or leads connected to the patient. This may disconnect tubes or
leads, restrict gas or liquid flow, or move sensors out of position.
Prolonged exposure to the light emitted by the observation lamp in this
unit may harm the unprotected eyes of the infant. For safety, cover the
infant’s eyes.
Do not use the Warmer system if the system failure alarm is activated.
Remove the unit from service and refer to qualified personnel for repair.
Radiant energy can adversely affect blood components. When using
intravenous tubing systems for delivery of blood components to patients
occupying a warmer, shield any tubing with aluminum foil.
When using a radiant warmer, change the patient’s diapers frequently.
Radiant energy causes more rapid urine evaporation, and may lead to
inaccurate urine diagnostic test/ analysis and inaccurate weight mea-
surements.

Precautions
Keep hands clear of the hinge area when installing a wall mounted
heater assembly. A pinch hazard exists.
The 3050 heater assembly weighs approximately 30 lbs (14 kg). Proper
installation may require two people. Due to the weight of the 3100 and
3150 units, approximately 75 lbs. (34 kg), proper installation will require
two people.

photo-
therapy lamp usage, etc.) or the patient condition requiring heater
adjustments in response to these changes. In the servo mode, the infant
warmer automatically adjusts heater output to maintain the desired skin
temperature, reducing (but not eliminating) the need to monitor the
patient and make adjustments to the equipment.
Use of electrosurgical units or other electrical field radiating equipment
can affect the operation of the warmer. Keep the patient probe lead as far
away as possible from electrosurgical cables. Do not allow excess electri-
cal cables to be laid on the bed platform. Use of electrosurgical units or
other instruments which radiate electrical fields can cause indirect
heating, by several tenths of a degree of the skin temperature probe due
to absorbed electrical energy. When using these devices near the radiant
warmer, operate the Infant Warmer in manual mode for maximum safety.
The use of phototherapy equipment may raise the patient’s temperature.
Radiant warmers increase an infant’s insensible water loss. Take appro-
priate measures to maintain the patient’s fluid balance while caring for
them in a radiant warmer.
Use only the Reusable Ohmeda skin temperature probe (Stock No. 0208-
0697-700) and heat reflective patches (Stock No. 0203-1980-300,

Precautions
Do not install chest drainage tubes in the Tubing Organizer Rear Side
Panel.
Install tubing in the appropriately sized holes. Use of inappropriate holes
may cause kinking, pinching or restriction of flow through the tubes, and
may interfere with the proper operation of therapy equipment.
Do not lower the Tubing Organizer Rear Side Panel with tubing attached.
Lowering can pull on the tubing, causing the tubes to dislodge from the
patient.
Do not move the warmer by pushing or pulling on the bed side panels.
This action may lead to the deterioration and breakage of the compo-
nents which form a safety barrier around the infant.
Ensure that the bedside panels are locked in position when a patient
occupies the bed. Blankets or other foreign objects may prevent the
latches from fully engaging.
Do not leave the patient unattended when the side panels are lowered.
Never place an infant on the X-ray cassette tray.
Do not place any foreign objects on the warmer bed or in the under bed
cavity while performing X-ray procedures. Incompatible materials in the
path of the X-ray may adversely affect the quality of the X-ray image. Use
of mattress or bedding materials other than those supplied by Ohmeda
should be evaluated by a Neonatologist or Radiologist.
Do not leave the patient unattended when using the warmer. Check the
patient’s temperature regularly to ensure the comfort and the safety of
the patient. If the warmer is used for an extended time, it is recom-
mended that the servo mode of operation be used. When an alarm is
silenced, close monitoring of the patient’s condition is required.
Use the servo mode unless the manual mode is specifically prescribed.
While both modes require patient monitoring, the manual mode requires
constant attention. In the manual mode, you must take the

time will allow simultaneous depletion of both
cylinders with no reserve oxygen supply available.
Use only one cylinder gasket per yoke. Use of more than one gasket could
cause leakage of the cylinder gas
Do not leave gas cylinder valves open if the pipeline supply is in use.
Pressures from both oxygen cylinders may become equal, and if simulta-
neously used, cylinder supplies may be depleted, leaving no reserve
supply in case of pipeline failure.
The patient probe is not isolated from earth ground. Any additional
equipment used with the Ohmeda Infant Warmer System must comply
with UL 544, CSA 22.2, IEC 601 and VDE 750.
The computer or RS-232 monitor’s user program must continuously check
the data link. The program should constantly verify connection to the
warmer controller and check for updated data.
Remote monitoring does not replace the need for direct patient
retrolen-
tal fibroplasia (retinopathy or prematurity). It is probable that even
concentrations of 40% or less oxygen (formerly considered safe) could be
dangerous to some infants. Therefore, arterial blood gas measurements
are extremely important for regulation of the concentration of inspired
oxygen when an oxygen-enriched environment is considered necessary.
(See current edition of “Standards and Recommendations for Hospital
Care of Newborn Infants” prepared by the Committee of Fetus and
Newborn of the Academy of Pediatrics.)
Do not leave both cylinder valves open. Leaving both oxygen cylinder
valves open at the same
50/pkg) to monitor the patient’s skin temperature. Use of
other manufacturer’s probes may affect the accuracy of warmer opera-
tion and the electrical safety of the patient.
The skin temperature probe should be located on the patient’s skin in an
area which is directly in the path of the radiant heat. It should not be
attached to an area which is shielded from the radiant heat or between
the patient and the mattress. Large temperature gradients and very long
servo response times will result from improper probe placement.
Rectal temperatures must never be used to servo control a patient’s
temperature.
Intimate contact between the skin temperature probe tip and the
patient’s skin must be maintained for accurate skin temperature mea-
surement. Underheating or overheating may result from poor contact
between the skin temperature probe and the patient. Verify that the skin
temperature probe is securely attached to the patient at least once every
half hour.
In the servo mode, verify that the patient temperature probe is securely
attached to the patient at least once every half hour. A dislodged probe
may not trigger an alarm. If the probe becomes dislodged, the warmer
can over or under heat the infant.

Use of cleaning/disinfecting solutions containing chemicals that are not
listed in the table on page 4-2 (i.e. alcohol, acetone, etc.), or chemicals in
greater concentrations than those listed, may damage the patient probe
or other material being cleaned.
Do not autoclave or gas sterilize the skin temperature probe. Do not
immerse the probe in liquid cleaner. Avoid placing excessive strain on
the probe lead. Always remove the probe by grasping the plug at the
panel. Do not pull on the probe lead. These precautions will help avoid
damage to the probe.
Do not autoclave or gas sterilize the mattress.

1.1 General
All models of the Ohmeda Infant Warmer System provide a controlled
source of radiant heat for infants and pediatric patients. The control
system uses a microprocessor and provides both manual and servo
modes of operation (model 2001 International is manual mode only). The
patient temperature, control temperature, and elapsed time displays are
digital for ease of viewing. The control panel includes a one hour elapsed
timer with time displayed in minutes and seconds. The timer features
optional audible tones for use during Apgar scoring. A complete audio
and visual alarm system is included on the control panel.
The optional

The heater assembly consists of a radiant heater, parabolic reflector,
observation light, and a visual alarm light. The parabolic reflector focuses
radiant energy on the bed surface, minimizing energy loss due to scatter-
ing and providing an even field of radiant heat over the bed surface. The
observation light provides intense light for procedures. The alarm light is
located on the end of the heater assembly for ease of viewing. The entire
heater assembly rotates to the side for X-ray procedures and for observa-
tion lamp replacement.
Control Unit
The control unit contains the electronic circuits and controls used to
operate the radiant heater and the observation light. The control unit
performs regular self checks during its operation including failure diag-
nostics.
Either manual or servo mode of operation may be selected. In the manual
mode of operation, select the level of radiant heat output as indicated by
the % power display on the control panel. The control circuit then main-
tains the selected level of radiant heat. The manual mode has a preheat
setting which allows the Warmer to be preheated. In the servo mode of
operation, select the patient’s control temperature. A skin temperature
probe is used to monitor the patient skin temperature. The control
system modulates the radiant heat to maintain the patient at the se-
lected control temperature. The patient’s skin temperature is continu-
ously displayed.
Alarms activate to alert the operator of a low or high patient tempera-
ture, a skin temperature probe failure, a power failure, equipment failure
or a check patient prompt.
1.5 Bed Platform
Warmers with beds include a mattress and transparent side panels. The
side panels fold down for easy access to the patient and can be removed
for cleaning. The X-ray cassette tray (located in an opening beneath the
bed when installed) pulls out for insertion of X-ray cassettes and allows
X-rays to be taken without moving the patient. * Markings located along
the side panels allow easy location of the cassette in the X-ray tray
relative to the position of the patient on the warmer bed.*
