ELCOME

Thank you for choosing the ResMed H UMID A IRE 3i™ humidifier. The H UMID A IRE 3i is designed to humidify (moisten) the air delivered to your airway during CPAP

(continuous positive airway pressure) therapy. The H UMID A IRE 3i attaches to your

ResMed S8™ Series CPAP flow generator with a simple ‘click-in’ mechanism.

This user manual contains the information you need for the correct use of your

H UMID A IRE 3i .

W

HAT IS THE

H

UMID

A

IRE

3i?

The H UMID A IRE 3i is designed to form a single unit with a ResMed CPAP flow generator. The combined unit provides humidification during CPAP therapy, and can make therapy more comfortable.

You may have experienced nasal congestion or dryness of the nose, mouth, or throat during CPAP therapy. These symptoms are caused by dry climates, cold air temperatures, the airflow delivered from your flow generator, or mouth leak. Moist air may help relieve these symptoms of dryness.

Refer to your flow generator manual to see whether it is compatible with the

H UMID A IRE 3i . Contact your equipment supplier or ResMed office if you require further information.

The H UMID A IRE 3i is indicated for humidification of the air delivered from the ResMed

S8 Series CPAP devices. The H UMID A IRE 3i is for use only as recommended by a physician.

C ONTRAINDICATIONS

The H UMID A IRE 3i is contraindicated for use with patients whose upper (supraglottic) airway has been bypassed. Please also refer to the relevant system manual for contraindications associated with CPAP therapy.

WARNINGS

Use the H UMID A IRE 3i only for its intended use as described in this manual.

Make sure that the water chamber is empty and thoroughly dried before transporting the H UMID A IRE 3i .

The H UMID A IRE 3i is designed only for use with specific ResMed CPAP devices.

Do not use the H UMID A IRE 3i with any other CPAP device.

The H UMID A IRE 3i should only be used with delivery tubes or accessories recommended by ResMed. Connection of other delivery tubes or accessories could result in injury, or damage to the device.

The H UMID A IRE 3i , including the associated tubing, is for single-patient use and must not be re-used on another person. This is to avoid the risk of cross-infection.

Always place the H UMID A IRE 3i device lower than the level of the patient. If it is placed at or above the level of the patient, heated water may flow down the air tubing and into the mask.

There exists the possibility that if the device is placed above the level of the patient and is tipped over, or if the tubing is filled with condensate, the mask might fill with water. The H UMID A IRE 3i should therefore be used with caution in patients who are unable to guard their airways, or are unable to pull the mask off, for example following a stroke. Attention should be given to the relative risks and benefits.

Do not attempt to dismantle the H UMID A IRE 3i docking station. There are no user-serviceable parts inside. Repairs and internal servicing should only be performed by an authorised service agent.

Take care when handling the H UMID A IRE 3i . The heater plate and the water in the water chamber may be hot.

If liquids are inadvertently spilled into or on the H UMID A IRE 3i docking station, unplug the CPAP device from the power outlet. Disconnect the docking station from the CPAP device and allow the docking station to drain and dry before using.

Do not operate the H UMID A IRE 3i if the CPAP device has a damaged power cord or plug.

Do not operate the H UMID A IRE 3i if it is not working properly or if any part of it has been dropped or damaged.

Keep the CPAP device power cord away from heated surfaces.

Do not drop or insert any object into any opening or tubes.

Do not use the H UMID A IRE 3i in the presence of flammable or explosive materials.

Explosion hazard—do not use in the vicinity of flammable anaesthetics.

If oxygen is used with this device, the oxygen flow must be turned off when the device is not operating.

If oxygen has been left on, turn off the flow generator, then wait 30 minutes before turning on the flow generator again.

Explanation : When the CPAP device is not in operation and the oxygen flow is left on, oxygen delivered into the air delivery tubing may accumulate within the

CPAP machine enclosure and create a risk of fire. This applies to most types of

CPAP machines.

Oxygen supports combustion. Oxygen should not be used while you are smoking or in the presence of an open flame.

Always ensure airflow is being generated by the device before the oxygen supply is turned on.

Always turn the oxygen supply off before stopping the airflow from the device.

Note : At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration will vary, depending on where the oxygen is introduced, the pressure settings, patient breathing pattern, mask selection and leak rate.

•

Start treatment at any time by pressing the Start/Stop key.

•

•

Access the menus by pressing Menu (Left key).

Stop the Warm-Up feature at any time by pressing Exit (Right key).

The Warm-Up feature will automatically turn off after 30 minutes if treatment has not started.

3 Turn the humidity control dial to the desired setting. The setting switches heated humidification off and delivers minimum humidification. The indicator light will remain lit to indicate standby mode. A setting of 6 ( ) delivers maximum humidification.

We recommend that you initially set the control dial to 3 ( ). If necessary, adjust the control dial up or down to find the setting that is most comfortable and effective for you. You can adjust the humidity setting at any time.

The aim is to have moist air delivered to your mask but to avoid condensation forming in the air tubing. The temperature and humidity of the surrounding air will affect the setting you need.

See “Frequently Asked Questions” for further tips on the correct humidity setting.

4 Fit your mask as described in your mask user instructions.

5 Press the Start/Stop key on the control panel. Alternatively, if your flow generator has the SmartStart function available, simply breathe into your mask and air should begin to flow.

Note : During operation, the indicator light becomes brighter to indicate that the heating element is active. Your HumidAire 3i has a rapid heating element which allows very short heating times. Do not be concerned if the light only brightens very briefly.

6 Lie down and arrange the air tubing so that it is free to move if you turn in your sleep.

!

WARNING

Do not leave an excessive length of air tubing around the top of your bed. It could twist around your head or neck while you are sleeping.

S TOPPING YOUR T REATMENT

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

Alternatively, if your flow generator has the SmartStart™ function available, simply remove your mask and treatment will end.

Some flow generators continue to blow air gently after you have stopped your treatment. This can continue for up to one hour to assist the heater plate in cooling.

However, you can unplug the device from the power outlet at any time and allow the heater plate to cool without airflow.

Q

UESTIONS

W HY IS THERE CONDENSATION IN MY MASK AND / OR AIR TUBING ?

You may experience excessive condensation in your mask or air tubing. This may occur seasonally, particularly when the room temperature is low or cool air is circulating around the tube. Turn the control dial down to a lower setting until the condensation decreases.

You may have to adjust your humidity setting from season to season.

D O I HAVE TO USE DISTILLED WATER IN THE WATER CHAMBER ?

Using distilled water will maximise the life of the water chamber and reduce mineral deposits. See “Cleaning your HumidAire 3i” on page 9 for further details.

W HAT IF I STILL HAVE SYMPTOMS OF DRYNESS ?

If you still experience symptoms of dryness, then your humidity setting may be set too low to be effective. Gradually turn the humidity control dial up over a few nights until the symptoms disappear.

If you are still experiencing symptoms of dryness, even after increasing the humidity setting, you may be breathing through your mouth. Mouth breathing or mouth leaks cause drying and irritation of the upper airway. If this is a problem, a full face mask or chin strap may help. Consult your clinician or equipment supplier for details.

Check that the power cord is plugged firmly into the power outlet and the switch (if available) is on at the outlet.

Try another power outlet.

Check that the docking station is securely attached to the flow generator.

• Your HumidAire 3i has a rapid heating element which allows very short heating times. Do not be concerned if the light only brightens very briefly.

• Turn the dial to the setting to switch heated humidification off. The indicator light will remain lit to indicate standby mode.

Clean the reflector with a damp cloth.

Indicator light is permanently dull and/or air does not feel warm
