Chapter 1: Warnings, Cautions, and Notes
WARNING: Indicates the possibility of injury to the patient or the operator.
CAUTION: Indicates the possibility of damage to the device.
NOTE: Places emphasis on an operating characteristic.
1.1 Warnings
General
e This is a service manual. It does not provide adequate information to allow proper operation of
the device for use in treating patients. Please refer to the device Clinical, Dealer, and/or Patient
Manuals for clinical use.
e This manual serves as a reference. It should be used in conjunction with the instructions and
protocol set by the physician at the institution where the device is being used. The instructions in
this manual are not intended to supersede established medical protocols regarding the use of
assist ventilators.
Safety
e The information contained in this section is supplemental to the warnings, cautions, and notes
contained in the Clinical, Dealer, and/or Patient Manuals for each device. Please read the
appropriate device manuals prior to servicing the unit.
e The BiPAP System is intended for use on adult patients (2 30 kg) only.
* The BiPAP System is intended for use with a Respironics, Inc. approved patient circuit only. A
Respironics approved circuit consists of :
ο. smooth inner lumen tubing;
e anexhalation device such as the Whisper Swivel® or Respironics Disposable
Exhalation Port Assembly; and
e anoninvasive patient interface (nasal mask, mouthpiece, or full face mask).
Additional accessories may be added to the circuit to meet specific needs. Every time changes
are made to the circuit configuration, the delivered pressures must be monitored at the patient
connection with the unit cycling.
‧ When operating the BiPAP S/T-D System with the Detachable Control Panel (DCP), the DCP
settings override the settings on the BiPAP S/T-D System’s control panel. DO NOT connect the
DCP to the BiPAP S/T-D System while the unit is turned on.
* Explosion Hazard - Do not use the BiPAP System in the presence of flammable anesthetics.
* Oxygen supports combustion. Oxygen should not be used while smoking or in the presence of
an open flame.
+ DO NOT add oxygen to the front of a BiPAP unit (at the inlet filter opening).

Operation
BiPAP System performance should be verified, as described in the Clinical Manual, before each
new patient is placed on the system.
The addition of accessories to the patient circuit (e.g., heated humidifier, bacteria filter, water
traps, and additional tube lengths) degrades pressure and flow delivery at the patient connection.
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 System 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 System. Always position the humidifier lower than both the
BiPAP unit and the patient.
Never attach oxygen tubing or any positive pressure source to the Pressure Port on the front
panel of the BiPAP S/T-D unit.
Service
Wiring connections and adjustments should be performed by authorized service personnel
ONLY.
Repairs and adjustments MUST be performed by experienced personnel who are fully ac-
quainted with this equipment. Service done by inexperienced, unqualified personnel or installa-
tion 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.
Cleaning
To avoid electrical shock, unplug the BiPAP unit before cleaning it.

Warnings, Cautions, and Notes 1-3
1.2 Cautions
{ CAUTI
ON: Federal law restricts this device to sale by or on the order of a physician. D
i
The DCP cable connector port is NOT a standard computer communications port.
Connecting the output port to a computer could damage the computer and the BiPAP unit.
On BiPAP S/T-D models, output signal pin connections are active. Care must be exercised to
prevent electrical shorting between the pin connections.
Only Respironics cables should be used. Use of any other cable types may cause damage to the
BiPAP S/T-D System.
For pressure monitoring, use only tubing with a smooth inner lumen.
When transporting or storing the BiPAP System, precautions should be taken to avoid exposure
to temperature extremes. If exposure to such temperatures has occurred, the unit should be
allowed to come to room temperature before being turned on.
The unit should be positioned on its base or rear panel for proper operation.
The voltage selector switch must be set according to local line voltage and the proper fuses used.
When using Respironics smooth inner lumen tubing without a heated humidifier, the overall
length of the tubing should not exceed twelve feet.
Regularly inspect the DCP cable.
Electromagnetic emissions: BiPAP Systems have been tested and shown to comply with FCC
Class B Subpart 15.J requirements and the IEC 601-1-2 requirements for electromagnetic
compatibility.
Operational verification of medical monitoring equipment used near the BiPAP System is recom-
mended to assure that any electromagnetic interference produced by the System unit does not
affect the function of the monitoring equipment.
1.3 Notes
The Inspiratory Positive Airway Pressure (IPAP) and Expiratory Positive Airway Pressure
(EPAP) controls are electrically coupled. The unit will not deliver an EPAP level that is higher
than the set IPAP level. If the EPAP control is set higher than IPAP, the unit will be locked to the
IPAP setting and the IPAP Light Emitting Diode (LED) will remain lit.
Circuit tubing with a smooth inner lumen and a nominal diameter of 22 mm is recommended.
Tubing with a corrugated inner lumen will cause a pressure drop from the blower outlet to the
patient connection. This may affect the unit's ability to deliver the maximum pressure.
Heat and moisture exchangers should not be used with the BiPAP System. Testing has shown
that the ability of the unit to maintain the prescribed pressure is significantly affected by the
addition of a heat and moisture exchanger to the patient circuit.
Additional Warnings, Cautions, and Notes are located throughout this manual.
