HOW TO USE THE S8 AUTOSET SPIRIT
STOPPING TREATMENT
To stop treatment at any time, remove your mask and press the Start/Stop key
or
if your clinician has enabled SmartStart, simply remove your mask and treatment will
end.
USING THE MASK-FITTING FEATURE
You can use the S8 AUTOSET SPIRIT 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.
To use the mask-fitting feature:
1 Fit your mask as described in the mask 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 operating. Your S8 device will ramp to the mask-fit pressure and will remain
at this pressure for three minutes.
The LCD also displays a mask-fit star rating. See “Definitions of Mask-Fit Star Rating”
on page 10.
Note: The mask-fit star rating display disappears after three minutes.
The mask-fitting feature can only be started from the RAMP or SETTLING screen.
In AutoSet mode, the mask-fit pressure is the highest pressure that you are likely to receive
based on the previous night’s session or 10 cmH
2
O, whichever is greater.
In CPAP mode, the mask-fit pressure is the set treatment pressure or 10 cmH
2
0,
whichever is greater.
3 Adjust your mask, mask cushion and headgear until you have a secure and comfortable
fit.
Once you have a secure and comfortable fit, check your mask-fit star rating on the
LCD screen. Table 4 explains the mask-fit star ratings.
Note: If there is another person nearby to check your mask-fit star rating, you can adjust
your mask, mask cushion and headgear while lying down.
