will vary, depending on the pressure settings, patient breathing pattern, mask
selection, and the leak rate.
WARNING
Always use the ResMed Oxygen Connector Port when adding supplemental
oxygen at the flow generator outlet.
Using the VPAP IV and VPAP IV ST
Setting up your VPAP
1 Connect the power cord to the socket at the rear of your VPAP.
2 Plug the other end of the power cord into the power outlet.

WARNING
• Make sure the power cord and plug are in good condition and the
equipment is not damaged.
• Only ResMed air tubing should be used with the device. A different type of
air tubing may alter the pressure you actually receive, reducing the
effectiveness of your treatment.
• Blocking the hose and/or air inlet of the device while in operation could lead
to overheating of the device.

Start/Stop Key
• Be careful not to place the device where it can be bumped or where
someone is likely to trip over the power cord.
• If you put the device on the floor, make sure the area is free from dust and
clear of bedding, clothes or other objects that could block the air inlet.
Attaching a H4i Humidifier
The H4i humidifier attaches to the front of a VPAP IV or VPAP IV ST device to provide
heated humidification. These devices automatically detect the presence of the H4i
and no other accessories are required for its use. For more information on using your
H4i, please refer to the H4i user guide.
WARNING
• Make sure that the water chamber is empty and thoroughly dried before
transporting the H4i.
• When using the travel bag, always separate the VPAP unit and the H4i and
place the H4i in its pouch.
How to Use the Control Panel

Using the Mask-Fitting feature
The VPAP IV and VPAP IV ST include a mask-fitting feature 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 minimise leaks.
To use the mask-fitting feature:
1 Fit your mask as described in the mask user instructions.
2 Hold down for at least three seconds until air pressure delivery starts and
the following screen appears:
MASK FIT:

Traveling with the VPAP IV and VPAP IV ST
!
International Use
Your VPAP 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.
Use on an Aircraft
Please consult the medical services department of your carrier if you intend to use
your VPAP device on an aircraft.
Note: You should not use your VPAP device while the aircraft is taking off or landing.
Use with DC Power
You must use a ResMed DC/DC Converter 24V/50W to connect your VPAP to a 12V
or 24V DC power source. Contact your equipment supplier or ResMed for details.
WARNING
The device should not be connected to both AC and DC power sources
simultaneously.

General Warnings and Cautions
!
!
Warnings
• Advice contained in this manual should not supersede instructions given by the
prescribing physician.
• A patient should not connect a device to the data communication port unless instructed
to do so by their health care provider or physician. Only ResMed products are designed
to be connected to the data communication port. Connecting other devices could result
in injury, or damage to the VPAP device.
• These VPAP devices should only be used with masks (and connectors
by ResMed, or by a physician or respiratory therapist. A mask should not be used unless
the VPAP device is turned on and operating properly. The vent hole or holes associated
with the mask should never be blocked.
Explanation: These VPAP devices are intended to be used with special masks (or
connectors
When the device is turned on and functioning properly, new air from the device flushes
the exhaled air out through the mask vent holes. However, when the device is not
operating, insufficient fresh air will be provided through the mask, and the exhaled air
may be rebreathed. Rebreathing of exhaled air for longer than several minutes can, in
some circumstances, lead to suffocation. This applies to most Positive Airway Pressure
devices.
• In the event of power failure
• These VPAP devices can be set to deliver pressures up to 25 cm H
event of certain fault conditions, pressures up to 40 cm H
• Follow all precautions when using supplemental oxygen.
• Oxygen flow must be turned off when the flow generator is not operating, so that
unused oxygen does not accumulate within the flow generator enclosure and create a
risk of fire.
• If the oxygen has been left on, turn off the device, then wait 30 minutes before turning on
the device again.
• At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration varies,
depending on the pressure settings, patient breathing pattern, mask, point of application
and leak rate.
• Do not use the VPAP IV or VPAP IV ST if there are obvious external defects or
unexplained changes in performance.
• Do not open the VPAP case. There are no user serviceable parts inside. Repairs and
internal servicing should only be performed by an authorised service agent.

Cautions
• At low pressures, the flow through the exhalation ports of your mask may not clear all
exhaled gas from the tubing. Some rebreathing may occur.
• The airflow for breathing produced by this device can be as much as 11ºF (6ºC) higher
than the temperature of the room. Caution should be exercised if the room temperature
is warmer than 90ºF (32ºC).
• When AC mains power (100–240V AC) is not available, always use a ResMed DC/DC
Converter 24V/50W. (The DC/DC Converter 24V/50W is available as an optional
accessory. It is not supplied with all models.)

The VPAP IV and VPAP IV ST devices are intended for use in the electromagnetic environment specified below. The customer or
the user of the VPAP device should assure that the device is used in such an environment.

Warnings: The VPAP device should not be used adjacent to or stacked with other equipment.
If adjacent or stacked use is necessary, the VPAP device should be observed to verify normal operation in the configuration in
which it will be used. The use of accessories (eg, humidifiers) other than those specified in this manual is not recommended.
They may result in increased emissions or decreased immunity of the VPAP device.
Recommended separation distances between portable and mobile RF communications equipment and the VPAP
series of devices
The VPAP device is intended for use in an environment in which radiated RF disturbances are controlled. The customer or the user
of the VPAP device can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the VPAP device as recommended below, according to the maximum
output power of the communications equipment.

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 device is used exceeds the applicable RF compliance level above, the VPAP device
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the VPAP device.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
