• In the clinical environment, any PC that is used with this device must be at

least 1.5 m away from, or at least 2.5 m above the patient. It must also

comply with IEC 60950 or equivalent.

Masks

You will also need a ResMed mask (supplied separately). For information on using your

Setting up the device

Place the device on a flat surface near the head of your bed.

!

CAUTION

• Be careful not to place the device where it can be bumped or where

someone is likely to trip over the power cord.

• Make sure the area around the flow generator is dry and clean. It should also

be clear of bedding, clothes and other potential blockages.

1 Connect the power cord.

Note: ResMed recommends using the AC power cord supplied with the unit. If a

replacement power cord is required, contact your ResMed service centre.

2 Plug the free end of the power cord into a power outlet.

!

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. Do not use conductive or anti-static hoses or

tubes.

4 Connect your mask system to the free end of the air tubing.

Attaching a Humidifier

!

WARNING

When using a humidifier, position it lower than your sleeping position, so that

any excess condensation drains back into the water chamber, and at the same

level or lower than the device.

Notes:

• You must activate the humidifier option in the menus if you are using a HumidAire or

Passover humidifier.

• For details on using humidifiers, please see you relevant user manual.

HumidAire 2i/2iC Humidifier

The HumidAire 2i or 2iC attaches to the front of the device to provide heated or passover

humidification, respsectively. No other accessories are required for its use. The

VPAP III ST-A with QuickNav automatically detects the presence of the HumidAire 2i.

HumidAire or Passover Humidifier

Medium size (52 cm) air tubing is a necessary accessory for connecting the device to the

HumidAire or Passover humidifier.

Note: Place the device on top of the humidifier. Do not place the device underneath the

humidifier. (This is to avoid water spilling into the device.)

Patient Standby Screens

The Patient Standby screens are displayed when the device is turned on. Depending on your

configuration and settings, these screens may display as follows.

Using the HumidAire 2i Warm-up Feature

*

If using a HumidAire 2i with the device, you can use the Warm-

up feature to pre-heat the water in the humidifier prior to

starting treatment. The humidifer will be automatically

detected when the device is turned on and the standby screen

will give you the option to start warming up the humidifier.

After stopping treatment, the device will continue to blow air

gently to assist cooling of the heater plate.

* If you do not have a H2i attached and/or your clinician has not enabled Ramp time, these options

will not appear.

Ramp Time

*

Ramp time is a feature which can be enabled by your clinician.

If you have difficulty becoming accustomed to the full pressure,

select a ramp time. The airflow will start very gently and slowly

increase to full operating pressure over the selected ramp time.

If your clinician has set a maximum ramp time, the Set Ramp

option is displayed on the Patient Standby screen. 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.

Patient Home Screen/Treatment Screen

This screen displays the time and date, the pressure bar and

the remaining Ramp time, if a Ramp time has been set.

Using the Mask-Fit Feature

This device includes a mask-fit feature to help you fit your mask properly. If a Ramp time is

selected, the mask can be adjusted at a pressure closer to the prescribed pressure. To use

the mask-fit feature:

1 Fit your mask as described in the user instructions.

2 Hold down the Start/Stop key for at least two seconds until air pressure delivery starts

1

.

The flow generator will ramp to the mask-fit pressure

2

and will remain at this pressure

for three minutes.

3 If necessary, adjust your mask, mask cushion and headgear to reduce leak and check

your mask-fit star rating again on the LCD screen.

4 After three minutes, treatment will begin.

• If you do not wish to wait three minutes, hold down the Start/Stop key for at least

two seconds and treatment will begin immediately.

• If you press the Start/Stop key for less than two seconds, the device will return to

standby mode.

Stopping Treatment

To stop treatment at any time, remove your mask and press the Start/Stop key

or

if the SmartStart function is enabled, simply remove your mask and treatment will end

(SmartStop is not applicable with the "Mir Full" mask setting and certain alarms; see

“SmartStart™” on page 10).

1 The mask-fit feature can also be accessed from the Patient Settings Menu.

2 The mask-fit pressure is the set treatment pressure or 10 cm H

2

O, whichever is greater.

The LCD also displays a mask-fit star rating from zero to

five stars. Three to five stars indicate a good fit. Zero to

two stars indicate that you should adjust your mask.

The mask-fit star rating display disappears after three

minutes.

11The Alarms

English

The Alarms

This device is fitted with alarms to alert you to changes that will affect your treatment.

Alarm Mute Key

You can mute an alarm by pressing the Alarm Mute key once. Pressing this key a

second time will un-mute the alarm. If the problem is still present, the alarm will sound again

after two minutes. An alarm LED will remain lit for as long as the problem is present. The

Title bar of the LCD will display the alarm description while the alarm is muted.

Testing the Alarm

When the device is turned on, the LEDs will flash and the alarm will beep to confirm that the

alarm is working.

Setting the Alarm Volume

You can set and test the alarm volume from the Patient Options Menu. The alarm will beep

at the selected volume when you press Enter.

All menus remain available during an alarm. Treatment screens are not viewable during an

alarm condition.

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 LCD screen will display either alarm information or

recommended instructions for you or your clinician.

Note: The alarm actions listed below are based on having the appropriate alarm settings for

your therapy. When an alarm is activated, consult your clinician.

!

CAUTION

In the event of power failure or machine malfunction, remove the mask to avoid

rebreathing your exhaled air.

Warning Signal/Cause Action

For all the medium priority alarms listed below, you will hear a

Warning Signal/Cause Action

13Cleaning and Maintenance

English

Cleaning and Maintenance

You should regularly carry out the cleaning and maintenance described in this section.

LCD: NO MASK VENT

• Connection of a non-vented mask.

• Mask expiratory flow port (vent)

may be blocked.

• Use of supplemental oxygen with

a vented mask.

• Ensure your mask has an expiratory flow port

(vent).

• Ensure your mask expiratory flow ports

(vents) are not blocked.

• Contact your clinician.

Note: The non-vented mask alarm activates within

30 seconds (15 sec on average) of using therapy

with a non-vented mask.

Daily Cleaning

Mask

Clean the mask according to the instructions supplied with the mask.

Air tubing

Disconnect the air tubing from the device (and humidifier, if used) and

store the tubing and mask in a clean, dry place until next use.

CAUTION

Do not store the air tubing in direct sunlight as the tubing may harden over

time and eventually crack.

Humidifier

If you are using a humidifier, clean it according to the instructions supplied

with the humidifier.

Weekly Cleaning

1

Remove the air tubing from the device and the mask.

2

Wash the air tubing in warm water using mild detergent. Rinse thoroughly, hang and

allow to dry.

3

Reconnect the air tubing to the air outlet and mask.

CAUTION

• Do not use bleach, chlorine-, alcohol- or aromatic-based solutions

(including all scented oils), moisturising or antibacterial soaps to clean the

air tubing or the device. These solutions may cause hardening and reduce

the life of the product.

• Do not hang the air tubing in direct sunlight as the tubing may harden over

time and eventually crack.

Periodic Cleaning

1

Clean the exterior of the device with a damp cloth and mild liquid soap.

2

Inspect the air filter to check if it is blocked by dirt or contains holes. See “Replacing the

Air Filter” on page 14.

Insert a new filter with the blue tinted side facing out.

Replace the air filter cover.

WARNING
