Using the S8 Series II

Setting Up

• 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.

• 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.
• Make sure the area around the device is dry and clean.

How to Use the Control Panel

The control panel of the S8 Series II includes an LCD screen which displays the menus and treatment screens as well as a keypad for navigating through the menus and delivering treatment.

The S8 Series II keypad has the following keys:

Key		Function
Start/Stop		Starts or stops treatment.
Up		Allows you to increase settings options and scroll through the S8 Series II menu.

The keypad and LCD are equipped with backlights that come on when the device is powered. The LCD backlight turns off after two minutes of inactivity, and comes back on when you press a key. The keypad backlight is always on while the S8 Series II is on.

Selecting the Mask Type

To ensure your device functions as intended with your selected mask, you need to select the mask type that you are using.

Using the Mask-fitting Feature

You can use the S8 Series II mask-fitting feature to help you fit your mask properly. This feature delivers air pressure for a three-minute period, prior to starting treatment, during which you can check and adjust your mask fit to minimise leaks.

Note: Make sure that the mask setting on the MASK screen is the same as the mask you are using.

1. Fit your mask as described in the mask user instructions.
2. With the RAMP or SETTLING screens displayed, hold down for at least three seconds until air pressure delivery starts.
   Your device will ramp to the mask-fit pressure and will remain at this pressure for three minutes.
   The following displays on the LCD screen indicating that the mask-fitting feature is operating, where: ***** is an excellent fit;****- is a very good fit; ***-- is a good fit; while **---, *---- and ----- each require you to adjust your mask.
   
3. Adjust your mask, mask cushion and headgear until you have a secure and comfortable fit.
   After three minutes, the pressure reverts to the set pressure and treatment will begin. If you do not wish to wait three minutes, hold down for at least three seconds to start treatment immediately.
   If you press for less than three seconds, the unit will return to standby mode (the RAMP or SETTLING screen).

Starting Treatment

1. Make sure the power is on.
   The product name is displayed briefly on the screen, then the standby screen displays RAMP (or SETTLING). The key and LCD backlights also turn on.
2. Lie down and arrange the air tubing so that it is free to move if you turn in your sleep.
   
   Do not leave long lengths of air tubing around the top of your bed. They could twist around your head or neck while you are sleeping.
3. Alter the ramp or settling time if required.
4. To start treatment, press .
5. Fit your mask as described in the mask user instructions.

Frequently Asked Questions

How will it feel when I am breathing with the S8 Series II?
When you first use your S8 Series II device, you may feel uncomfortable breathing against the airflow. This is normal. You will continue to breathe normally while you sleep. The EPR setting may also improve comfort. Take time to adjust to this new sensation.

What do I do when I want to get up in the night?
If you need to get up during the night, remove your mask and stop therapy. Always remember to restart therapy and put your mask on when you return to bed.

What do I do if I feel air leaking out of the mask?
The S8 Series II 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. For example, try repositioning the mask and adjusting the straps. If you are 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.
If you are using a full face mask and 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.

Anything special I should do before putting the mask on?
efore 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. Do not use moisturiser when wearing a mask.

My mouth feels dry during treatment—what can I do?
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.

My nose is irritated during treatment—what can I do?
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 clinician or equipment supplier for advice.

Can I travel with the S8 Series II?
Your S8 Series II has an internal power supply 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 the region in which you are using the device.
Your S8 Series II device automatically adjusts to changes in altitude up to 2,591 m.
