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.

Care of Newborn Infants" prepared by the Committee of Fetus and
Newborn of the Academy of Pediatrics.)

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.
Oxygen concentrations higher than 40% can increase the risk of
