38 Using the device
7.
Put the mask on. If automatic mode has been
selected (see page 76), the device is turned on by
the patient‘s breathing. If automatic mode has
been set to „OFF“, the device is started by press-
ing the ON/OFF key.
8. The device fi rst of all runs (for the time selected by
you for the mask test) at the prescribed pressure.
You should now ensure the mask‘s correct posi-
tioning to avoid potential leakages.
9. Place the tube in such a way that it does not exert
any strain on the mask when you lie down.
10.
Now breath deeply and calmly, just through your
nose. If the soft start function (Ramp) has been
selected (see page 73), the device reduces air pres-
sure after the mask test has been performed. It
then increases pressure automatically gradually up
to the prescribed value while you can go to sleep
under reduced pressure.
Read how you can adapt the time settings for mask
test and ramp to suit your personal requirements
in section „Device functions“ (starting page 44).
