1Introduction
The Puritan Bennett KnightStar®330 Bi-Level®Ventilator
assists patients who are being treated for respiratory
insufficiency or Obstructive Sleep Apnea (OSA) in the
home, hospital, or institutional setting. It is also used to
treat respiratory failure in the hospital setting.
The KnightStar 330 is designed to prevent the upper airway
from being obstructed by delivering air pressure through
an interface (mask or nasal pillows) using one of three
different modes; Inspiratory/Expiratory Positive Airway
Pressure (I/E PAP), Assist Control (A/C), or Continuous
Positive Airway Pressure (CPAP).
I/E PAP mode allows you to breathe at separate inspiratory
and expiratory pressure levels, while CPAP mode provides
a single, continuous breathing pressure. These pressure
levels are set by your clinician so that they provide
enough pressure to keep the airway open while
maintaining a comfortable breathing effort while you
sleep. A/C mode ventilates patients just as I/E PAP mode
with the additional features of a settable backup
ventilation respiratory rate and I:E ratio.
Patients using the KnightStar 330 should weigh at least
30 kg (66 lbs) and be able to breathe on their own.
Read this entire booklet before using the
KnightStar 330. It will help you use the device safely
and effectively. If you have any questions about the
device or its use, contact your physician or home care
provider.

KnightStar 330 User’s Manual Y-500009-00 Rev. J (6/06)
1.1 Warnings, Cautions, and Notes
The following words and symbols found in this manual
have special significance:
Review the following messages prior to using the
KnightStar 330:
Warnings alert the user to potential serious
outcomes (death, injury, or adverse events) to
the patient or user.
Cautions alert the user to exercise care necessary
for the safe and effective use of the
KnightStar 330.
Notes indicate information of particular interest
for more efficient and convenient operation.
When using this equipment, it is important
that you read, understand, and follow the
instructions and warnings in this user’s
manual.
There is no audible alarm built into the
KnightStar 330 to indicate that the patient has
stopped breathing.
Under certain conditions, some alarms may
not occur. For example: (1) the leak alarm
may not occur if patient breath efforts are not
detected, as in the case of excessively large
leaks; and (2) the low pressure alarm may not
occur under conditions such as an incorrect
alarm threshold setting or air pathway
resistance.

Introduction 1
Y-500009-00 Rev. J (6/06) KnightStar 330 User’s Manual
1-3
This product is intended for use only as
prescribed by a physician.
The KnightStar 330 and all other bi-level
pressure devices should only be used with
interfaces and breathing circuits
recommended by the device’s manufacturer
or by your physician.
An interface should not be used unless the
device is turned on and operating properly.
When the device is turned on and functioning
properly, fresh air from the device flushes the
exhaled air out through the interface vent
hole(s). However, when the device is not
operating, a substantial proportion of
exhaled air, including carbon dioxide (CO2)
may be rebreathed. Prolonged rebreathing of
carbon dioxide can increase CO2 levels and, in
some circumstances, may even result in
death. DO NOT BLOCK THE INTERFACE VENT
HOLE(S).
At low pressure settings, the flow through the
vent hole may be inadequate to clear all
exhaled air from the tubing. Some
rebreathing may occur.
For your health and comfort, clean the
KnightStar 330, interface, and breathing
circuit regularly before use. Refer to
Section 3.5, on page 3-11, or follow the
cleaning instructions that came with your
interface and breathing circuit.
Set up the KnightStar 330 system as shown in
this manual for safe and effective operation.

KnightStar 330 User’s Manual Y-500009-00 Rev. J (6/06)
To reduce the risk of strangulation, be sure to
route the tubing away from the head.
Keep the breathing circuit and power cord
away from heated surfaces.
Patients who receive supplemental oxygen
should be aware that hazards exist with
combustible materials and flames or sparks in
the presence of oxygen. Do not smoke in the
presence of oxygen.
At a fixed flow rate of supplemental oxygen,
the inhaled oxygen concentration will vary
depending upon pressure settings, patient
breathing patterns, mask or nasal interface
selection, and leak rate.
Explosion Hazard - This equipment is not
suitable for use in the presence of a
flammable anaesthetic mixture with air, or
with oxygen or nitrous oxide.
The KnightStar 330 should never be operated
where gases from external sources, gas
stoves, engine exhaust, or anesthesia
machines could be combined with air at the
inlet. Placing the unit in such an area may
result in asphyxiation.

To avoid electrical shock:
• Do not use if power cord or plug is
damaged
• Unplug all power cords before
cleaning
• Do not use near water such as sinks,
showers or bathtubs, where water
could spill onto the device
• If you suspect that water has entered
the KnightStar 330, unplug the power
cord and let device dry before using
Never drop or insert any object into the air
outlet or any other opening on the unit or
breathing circuit.
Should you experience nasal or airway
dryness, skin sensitivity, runny nose, ear pain,
sinus discomfort, daytime sleepiness, mood
change, disorientation, or memory lapse
when using this device, discontinue use and
call your physician.
Contact your home care company if the
equipment malfunctions in any way. Do not
attempt to open the device case. Only
qualified personnel may service this
equipment.
If the display indicators on the unit are
inoperative, the unit must be checked by the
proper personnel.

KnightStar 330 User’s Manual Y-500009-00 Rev. J (6/06)
Always place the KnightStar 330 upright on a
firm, flat surface, and use only approved
accessories. Placing the device on uneven
surfaces, using it in an improper orientation,
or using unapproved accessories could result
in the device tipping over, causing damage or
possible patient injury.
The KnightStar 330 should be used with care
to avoid overheating the patient when the
room temperature exceeds 90oF (32.2oC),
since under certain conditions the patient
outlet gas flow can be as much as 6.7oF
(3.7oC) degrees warmer than room
temperature.
The KnightStar 330 equipment has been
tested and found to comply with the limits for
medical devices to IEC 601-1-2:2001 (or EN
60601-1-2:2001 or Medical Device Directive
93/42/EEC). This testing shows the device
provides reasonable protection against
harmful interference in a typical medical
installation. However, there is no guarantee
that interference will not occur in a particular
installation, for example, in the presence of
portable and mobile RF communication
devices. If this equipment does cause harmful
interference to other devices or is negatively
impacted by other devices, the user is
encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the devices
• Increase the separation between the
devices
• Connect the equipment to an outlet
on a different circuit
• Consult the manufacturer or field
service technician for help

Do not set the KnightStar 330 on or within
3 feet (1 m) of electric or electronic
appliances, such as space heaters, electric
blankets, or televisions. Do not operate
cordless phones near the device. Doing so
may result in device malfunction.
Be careful when handling the KnightStar 330
during or immediately after use. Under
specified operating conditions, some surfaces
of the unit may become hot to the touch. This
is a normal occurrence and is typical of this
type of device.
Always operate the KnightStar 330 with the
outlet filter in place. Failure to do so could
increase your risk of infection or contaminant
inhalation.
Inspect the inlet air filter often. Remove the foam
filter from the rear panel and clean it at least
once per week, or more often in dusty
environments. Let the filter air dry completely
before reinstallation.
See Section 3.5.3 on page 3-12 for information
on cleaning the inlet air filter.
Start the KnightStar 330 system before putting
on the interface.
Federal (USA) law restricts this device to sale by
or on the order of a physician.
At the end of the KnightStar 330's useful life,
return the device to the manufacturer for proper
disposal.
