English
Introduction
The VPAP™ III ST-A is a bilevel pressure support ventilator specifically designed
for non-invasive mask ventilation.
This user manual contains the information you need for the correct use of your
VPAP III ST-A.
User/Owner Responsibility
The user or owner of this system shall have sole responsibility and liability for any
injury to persons or damage to property resulting from:
•operation which is not in accordance with the operating instructions supplied
•maintenance or modifications carried out unless in accordance with
authorized instructions and by authorized persons.
Please read this manual carefully before use.
This manual contains special terms and icons that appear in the margins to draw
your attention to specific and important information.
•Warning alerts you to possible injury.
•Caution explains special measures for the safe and effective use of the
device.
•Note is an informative or helpful note.
Medical Information
What the VPAP III ST-A is Intended for
The VPAP III ST-A system is intended to provide non-invasive ventilation for
patients with respiratory insufficiency or obstructive sleep apnea (OSA), in the
hospital or home.
Contraindications
The VPAP III ST-A should not be used if you have an insufficient respiratory drive
to endure brief interruptions in non-invasive ventilation therapy. The
VPAP III ST-A is not a life support ventilator and may stop operating with power
failure or in the unlikely event of certain fault conditions.
If you have any of the following conditions, tell your doctor before using the
VPAP III ST-A:
•acute sinusitis or otitis media
•epistaxis causing a risk of pulmonary aspiration
•conditions predisposing to a risk of aspiration of gastric contents
•impaired ability to clear secretions

6
•hypotension or significant intravascular volume depletion
•pneumothorax or pneumomediastinum
•recent cranial trauma or surgery.
Warnings
•The entire manual should be read before using the VPAP III ST-A.
•Advice contained in this manual should not supersede instructions given by
the prescribing physician.
•The VPAP III ST-A should be used with masks and accessories recommended
by ResMed or the prescribing physician. Use of incorrect masks and
accessories may adversely affect the function of the VPAP III ST-A.
•The VPAP III ST-A is designed for use with masks that allow exhaled gases to
be flushed out through vent holes. Exhaled gases will be rebreathed if the
mask is worn with the machine turned off, or the vent holes are occluded. If
this occurs over prolonged periods, suffocation may occur.
•In the event of power failure or machine malfunction, remove the mask.
•The VPAP III ST-A can be set to deliver pressures up to 30 cm H2O. In the
unlikely event of certain fault conditions, pressures up to 40 cm H2O are
possible.
•The VPAP III ST-A is not suitable for use in the vicinity of flammable
anesthetics.
•The VPAP III ST-A should not be used with anesthetized patients, whose
breathing depends entirely on mechanical ventilation.
•If oxygen is used with the VPAP III ST-A, the oxygen flow should be stopped
when the device is not operating. If oxygen flow continues when the device
is not operating, oxygen may accumulate within the device and create a risk
of fire.
•Do not use the VPAP III ST-A if there are obvious external defects,
unexplained changes in performance or unusual noises.
•Do not open the VPAP III ST-A case. There are no user serviceable parts
inside. Repairs and internal servicing should only be performed by an
authorized service agent.
Cautions
•At low EPAP pressures, the flow through the mask vent holes may be
inadequate to clear all exhaled gases, and some rebreathing may occur.
•The air flow for breathing produced by this device can be as much as 6oC
higher than the temperature of the room. Caution should be exercised if the
room temperature is warmer than 32oC.
Note: The above are general warnings and cautions. Further specific warnings,
cautions and notes appear next to the relevant instructions in the manual.

7Medical Information
English
Adverse Effects
You should report unusual chest pain, severe headache or increased
breathlessness to your physician. An acute upper respiratory tract infection may
require temporary discontinuation of treatment.
The following side effects may arise during the course of therapy with the
VPAP III ST-A:
•drying of the nose, mouth or throat
•bloating
•ear or sinus discomfort
•eye irritation
•mask-related skin irritations
•chest discomfort.

11Setting up the VPAP III ST-A System
English
Setting up the VPAP III ST-A System
Please refer to the illustrations in section Dof the illustration sheet.
Setting up the VPAP III ST-A
1Place the VPAP III ST-A on a flat surface near the head of your bed. If the device
is placed on the floor, ensure that the area is free from dust and clear of bedding,
clothes or any other objects that could block the air inlet.
!
CAUTION
Be careful not to place the device where it can be bumped or where
someone is likely to trip over the power cord.
2Connect the power cord
There are two sockets at the rear of the flow generator—the top one for an AC
(standard mains electricity) and the lower one for a DC power cord (see “Using
a Battery to Power the VPAP III ST-A” on page 37).
ResMed recommends using the AC power cord supplied with the unit.
If the customized ResMed power cord is supplied, it can be held in place with
the locking clips. To insert the locking clip, pinch the free ends together and fit
the pins into the holes on both sides of the socket. Insert the power cord into the
socket. Push the locking clip down so that the groove holds the power cord in
place.
Plug the free end of the power cord into a power outlet (D-1).
!
CAUTION
Do not connect both AC and DC power cords to the VPAP III ST-A at the
same time.

12
!
WARNING
•Make sure the power cord and plug are in good condition and the
equipment is not damaged.
•The air filter cover protects the device in the event of accidental liquid
spillage onto the device. Ensure that the air filter and air filter cover are
fitted at all times.
3Connect one end of the air tubing firmly onto the air outlet of the VPAP III ST-A
(D-2).
!
WARNING
Only ResMed air tubing should be used with your flow generator. A
different type of air tubing may alter the pressure you actually receive and
reduce the effectiveness of your treatment.
4Assemble your mask system according to the mask user instructions.
5Connect your mask system to the free end of the air tubing (D-3).
The VPAP III ST-A system is now assembled (D-4). To start treatment, see
“Starting Treatment” on page 17.
Attaching a Humidifier
!
WARNING
When using a humidifier, position it lower than you, and at the same level
or lower than the VPAP III ST-A.
Note: You must activate the humidifier option in the menus if you are using a
HumidAire or Passover humidifier.
Attaching a HumidAire 2i Humidifier
Please refer to the illustrations in section Eof the illustration sheet.
The HumidAire 2i attaches to the front of the VPAP III ST-A to provide heated
humidification. No other accessories are required for its use. The VPAP III ST-A
automatically detects the presence of the HumidAire 2i. No menu changes are
required. Please refer to the HumidAire 2i User’s Manual for details.
Attaching a HumidAire 2iC Humidifier
Please refer to the illustrations in section Fof the illustration sheet.
The HumidAire 2iC attaches to the front of a VPAP III ST-A to provide passover
humidification. No other accessories are required for its use. Please refer to the
HumidAire 2iC User’s Manual for details.
Attaching a HumidAire Humidifier
