3Warnings, Cautions, and Notes
Warnings continued
• The addition of accessories to the patient circuit (e.g., heated humidifier, main flow bacteria filter,
water traps, and additional tube lengths) affects pressure and flow delivery at the patient
connection. Clinical assessment must confirm that the delivered pressures and flows are
adequate for patient management when circuit accessories are used. It may be necessary to
increase pressure delivery to compensate for the increased resistance of the circuit.
• When the BiPAP S/T is used with a heated humidifier, that manufacturer’s specifications should
be checked to confirm that the humidifier will function correctly in the presence of the
continuous flow from the BiPAP S/T System. Always position the humidifier lower than both the
BiPAP unit and the patient.
• When the BiPAP S/T System is used with a heated humidifier, water traps must be placed in the
patient circuit.
• As with any pressure-limited ventilation system, particular caution must be exercised in caring
for patients with changing respiratory system compliance and resistance, because this may affect
the adequacy of ventilatory support.
• Wiring connections and adjustments should be performed by authorized service personnel only.
• Repairs and adjustments must be performed by experienced personnel who are fully acquainted
with this equipment. Service done by inexperienced, unqualified personnel or installation of
unauthorized parts could cause personal injury, invalidate the warranty, or result in costly
damage. Contact Respironics, Inc. or your health care dealer if the unit fails to meet
performance specifications.
• To avoid electrical shock, disconnect the electrical supply before changing the fuses.
• Replace fuses with those of the same type and rating only.
• To avoid electrical shock, unplug the BiPAP unit before cleaning it.
Cautions
• Federal law restricts this device to sale by or on the order of a physician.
• For pressure monitoring, use only tubing with a smooth inner lumen.
• When transporting or storing the BiPAP S/T, take precautions to avoid exposure to temperature
extremes. If exposure to such temperatures occurs, allow the unit to come to room temperature
before turning it on.
• Position the unit on its base or rear panel for proper operation.
• Ensure that the voltage selector switch is set according to local line voltage and the proper fuses
are used.
• When using Respironics smooth inner lumen tubing without a heated humidifier, the overall
length of the tubing should not exceed 12 feet.
• Remove the mask before turning the BiPAP unit off.
• Electromagnetic emissions: BiPAP S/T Systems have been tested and shown to comply with
FCC Class B Subpart 15.J requirements.
• Verifying the operation of medical monitoring equipment used near the BiPAP S/T is
recommended to ensure that any electromagnetic interference produced by the unit does not
affect the function of the monitoring equipment.
