Using The Mask Fitting Feature - ResMed S8 AutoSet Spirit II Clinical Manual

Using the Mask Fitting Feature

The S8 AutoSet Spirit II mask-fit feature delivers air pressure for a three-minute
period before therapy begins for adjusting mask fit to minimise leak. It is
particularly useful for patients receiving AutoSet mode therapy at home. It
allows them to assess mask fit at typical treatment pressure at the start of the
night, when pressure delivered is normally quite low.
The S8 AutoSet Spirit II system should be set up beside the patient's bed with
the air tubing and mask system connected. (See "System Setup" on page 11.)
1
Instruct the patient to lie down in bed. If desired, place the tubing over the top of
the headboard to reduce drag on the mask.
WARNING
!
Do not leave long lengths of air tubing around the top of the bed; they may
twist around the patient's head or neck while sleeping.
2
Instruct the patient to put the mask on according to the mask user instructions.
3
Hold down the Start/Stop key on the control panel (see Figure 4, S8 AutoSet
Spirit II Keypad and LCD, on page 15) for at least 3 seconds until pressure
delivery starts and the following screen appears:
Note: When the device is in AutoSet mode, the mask-fit pressure is the 95th
centile pressure of the previous treatment session, or 10 cm H
greater. Note that 95th centile pressure is the pressure that has been exceeded
for only 5% of the night. When the device is in CPAP mode, the mask-fit
pressure is the set treatment pressure, or 10 cm H

Adjust the mask, cushion and headgear to achieve optimal fit.
