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
Introduction

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.
o
• The air flow for breathing produced by this device can be as much as 6 C
higher than the temperature of the room. Caution should be exercised if the
o
room temperature is warmer than 32 C.
•
Note: The above are general warnings and cautions. Further specific warnings,
cautions and notes appear next to the relevant instructions in the manual.
2
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.

Using the HumidAire 2i Warm-up Feature
If using a HumidAire 2i with the VPAP III ST-A, you can use the Warm-up feature
to pre-heat the water in the humidifier prior to starting treatment.
After stopping treatment, the VPAP III ST-A will continue to blow air gently to
assist cooling of the heater plate.
See the HumidAire 2i User’s Manual for further details.
Using the Mask-Fitting Feature
The VPAP III ST-A mask-fitting feature can be used to help you fit your mask
properly. The mask-fitting feature delivers air pressure for a three-minute period,
prior to starting treatment, for checking and adjusting your mask fit to minimize
leaks. If a Ramp time is selected, the mask can be adjusted at a pressure closer
to the prescribed pressure. To use the mask-fitting feature:
1. Fit your mask as described in the user instructions.
2. Hold down the Start/Stop key for at least three seconds until air pressure
delivery starts.
The following display will appear on the LCD screen indicating that the
mask-fitting feature is in operation. The flow generator will ramp to the MaskFit pressure and will remain at this pressure for three minutes. A Mask-Fit
star rating is also displayed. See “Definitions of Mask-Fit Star Rating” on
page 15.

How to Use the VPAP III ST-A Menus
The VPAP III ST-A provides a set of functions arranged in menus and submenus.
Via the LCD screen, the menus and submenus allow you to view and change the
settings for a particular function. You can access the menus regardless of
whether the VPAP III ST-A is in standby mode or delivering therapy.
Your clinician has preset the menu to either a standard view or a detailed view.
Both of these menus are explained below.
When the VPAP III ST-A is turned on, a Welcome screen is displayed. After the
device self-checks are complete, the VPAP (or Ramp) screen appears.
Ramp Screen
If your clinician has set a maximum ramp time, the Ramp screen is displayed
after the Welcome screen. On the Ramp screen, you can immediately set a ramp
time. Ramp time is the period during which the pressure increases from a low
pressure to the prescribed treatment pressure. See “Ramp Time” on page 13.
Ramp time can be altered in five-minute increments (from OFF to a maximum
ramp time set by your clinician) by using the Up/Down key.
How to Use the Standard Menu
The standard menu allows you to view details about the time used, a summary
of your device settings, and the current software version of your VPAP III ST-A.
The Used (time) screen displays the total number of hours for which the device
has been used. It also displays the number of days the VPAP III ST-A was used
out of the total number of days available for use.
For details on the settings summary screens, see “Settings Summary Screens”

Alarms Troubleshooting
The most common reason for an alarm to sound is because the system has not
been properly assembled. Check that the air tubing has been properly attached
to the flow generator and mask (and humidifier if used).
When an alarm has been activated, the bottom line of the LCD screen will display
either alarm information or recommended instructions for you or your clinician.

Helpful Hints
Starting out
Mouth Leaks
If using a nasal mask, try to keep your mouth closed during treatment. Air leaks
from your mouth can decrease the effectiveness of your treatment. If mouth
leaks are a problem, a full face mask or chin strap may help. Contact your clinician
or equipment supplier for further details.
Mask Fitting
The flow generator delivers the most effective treatment when the mask is well
fitted and comfortable. Treatment can be affected by leaks, so it is important to
eliminate any leaks that may arise.
If you have problems trying to get a comfortable mask fit, contact your clinician
or equipment supplier. You may benefit from a different size or style of mask.
You can also use the Mask-Fitting feature to help you fit your mask properly. See
“Using the Mask-Fitting Feature” on page 14.
Before wearing your mask, wash your face to remove excess facial oils. This will
allow a better fit and prolong the life of the mask cushion.
Nasal Irritation
Dryness
You may experience dryness of the nose, mouth and/or throat during the course
of treatment, especially during winter. In many cases, a humidifier may resolve
this discomfort. Contact your clinician for advice.
Runny or Blocked Nose
You may experience sneezing and/or a runny or blocked nose during the first few
weeks of treatment. In many cases, nasal irritation can be resolved with a
humidifier. Consult your clinican for advice.
Travelling with the VPAP III ST-A
International Use
Your VPAP III ST-A flow generator has an internal power adapter that enables it
to operate in other countries. It will operate on power supplies of 100–240V and
50–60Hz. No special adjustment is necessary, but you will require an approved
power cord for that country.
Using a Battery to Power the VPAP III ST-A
The VPAP III ST-A can be powered by battery using the ResMed DC-24/30
Converter, an inverter or a UPS (uninterruptible power supply).
Battery Requirements
We recommend a 12V or 24V deep-cycle battery. Battery capacity is determined
by VPAP III ST-A's power consumption which is mainly affected by the IPAP
pressure, usage hours and whether or not an integrated humidifier is connected.
Helpful Hints
33
Please refer to the VPAP III Series Battery Power Guide for the recommended
battery type and capacity, or contact ResMed's Technical Services division for
your specific application.
ResMed DC-24/30 Converter
ResMed supplies the DC-24/30 Converter (product code: 22015) which is
compatible with the DC input of the VPAP III ST-A. This is an accessory that may
be purchased separately through your ResMed distributor.
The DC-24/30 Converter can be connected to a 12V or 24V battery, or a cigarette
lighter socket (in a vehicle). When using a DC power supply, the power is turned
on and off via the switch on the converter, and not the power switch at the back
of the VPAP III ST-A. No power will be supplied to the HumidAire 2i integrated
humidifier when connected to a VPAP III ST-A using a converter.
Please refer to the DC-24/30 Converter instructions for further details.

NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the VPAP III ST-A is used exceeds the applicable RF compliance level above, the VPAP III ST-A should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the VPAP III ST-A.
