Warnings
AWarning indicates the possibility of injury to you or the
operator of the device.
• This manual serves as a reference. The instructions in
this manual are not intended to supersede the
instructions of your care giver.
• The Harmony S/T ventilator is not intended to provide
the total ventilatory requirements of the patient.
• The prescribed patient settings must be adjusted by
trained and authorized personnel only. Do not attempt
to open the top lid of the unit.
• Use only the patient circuit provided by your home
care provider.
• When using a patient circuit that contains a Whisper
Swivel®II or other exhalation device, do not tape, seal,
or otherwise block the vent openings. Doing so may
result in asphyxia.
• Oxygen supports combustion. Oxygen should not be
used while smoking or in the presence of an open flame.
• Exercise caution when using the Harmony S/T ventilator
if the room temperature is greater than 95 °F (35 °C). At
high room temperatures, the air from the unit can cause
discomfort or irritation to your nasal passages and your
airway.
•Do not use the Harmony S/T if the breathing circuit
connection is blocked.
• When the Harmony S/T ventilator is used with a
humidifier, be sure that the humidifier is lower than both
the unit and you.
• Repairs and adjustments must be performed by
Respironics-authorized service personnel ONLY.
Service done by inexperienced, unqualified personnel or
installation of unauthorized parts could cause injury,
invalidate the warranty, or result in costly damage.
• Periodically inspect electrical cords for damage or signs
of wear.
• To avoid electrical shock, unplug the Harmony S/T unit
before cleaning it.
• Immediately report any unusual chest discomfort,
shortness of breath, or severe headache to
your physician.
• If the unit is dropped or if you notice any changes in the
operation, contact your home care provider.

Cautions
A Caution indicates the possibility of damage to the device.
• Federal law restricts this device to sale by or on the order
of a physician.
• Do not expose the Harmony S/T ventilator to tempera-
tures at or near the extremes of those shown below. If
exposure to such temperatures has occurred, allow the
unit to come to room temperature before turning it on.
Temperatures
Operating: 5 °C to 40 °C
Transport/Storage: -20 °C to 60 °C
• The unit must be positioned on its base for
proper operation.
• Do not place the unit such that any side or the bottom of
the unit may not have adequate air circulation.
• A properly installed, undamaged inlet filter is required
for proper operation.
• Never place liquids on or near the Harmony S/T unit.
• If the External Battery Discharged Alarm is activated,
disconnect the external battery immediately.A dis-
charged battery may be damaged if it continues to be
connected to the ventilator.

S/T Patient Guide
Intended Use/Indications for Use
The BiPAP Harmony S/T is a non-invasive, pressure
support ventilator used to augment the breathing of
patients suffering from acute or chronic respiratory
insufficiency, or to maintain airway patency and provide
ventilatory support to patients who experience obstructive
sleep apnea.
It is not intended to provide the total ventilatory
requirements of the patient.
The Harmony S/T is intended for use in the home,
hospital, or other institutional settings.
Contraindications
The Harmony S/T ventilator should not be used if you
have severe respiratory failure without a spontaneous
respiratory drive.
If any of the following conditions apply to you, consult
your physician before using the Harmony S/T ventilator.
Consult your physician if you have:
• the inability to maintain a patent airway or adequately
clear secretions.
• a risk of aspiration of gastric contents.
• acute sinusitis or otitis media.
• an allergy or hypersensitivity to the mask materials
where the risk
from allergic reaction outweighs the benefit of ventila-
tory assistance.
• epistaxis.
• hypotension.
The following are potential side effects of noninvasive
positive pressure therapy:
• Ear discomfort
• Conjunctivitis
• Skin abrasions due to noninvasive interfaces
• Aerophagia (gastric distention)

2 Introduction to the Harmony S/T
What is Bi-Level Ventilation?
Bi-level ventilation with the Harmony S/T Ventilatory
Support System helps you to breathe by supplying two
levels of air pressure. The Harmony S/T provides a higher
pressure—known as IPAP (Inspiratory PositiveAirway
Pressure)—when you inhale, and a lower pressure—
known as EPAP(Expiratory Positive Airway Pressure)—
when you exhale. The higher pressure opens your airway
to increase the amount of air going into your lungs, and the
lower pressure makes it easier for you to exhale while still
keeping your airway open.
NOTE:Occasionally, cosmetic changes may be made to
the product that do not affect the performance or
specifications of the product. These kinds of
changes do not warrant a reprinting of this
manual. Illustrations are for reference only.

S/T Patient Guide
What is the Harmony S/T?
The Harmony ventilator, shown in Figure 2-2, supplies
two levels of air pressure through a breathing circuit. The
circuit consists of:
• circuit tubing to deliver the air from the ventilator to
your interface (e.g., mask)
• an exhalation port to vent exhaled air from the circuit
• a mask or other interface to deliver the ventilation to
your nose or nose and mouth, depending on which
interface has been prescribed for you
The system senses your breathing effort and changes
pressure levels when you inhale and exhale.
