How to Use the VPAP Menus
The VPAP unit provides a set of functions arranged in menus and submenus.
Via the LCD screen, the menus and submenus allow you to view and change
the settings for a particular function. You can access the menus regardless
of whether the VPAP is in standby mode or delivering therapy.
Your clinician has preset the menu to either a standard view or a detailed
view. Both of these menus are explained below.
When the VPAP is turned on, a Welcome screen is displayed. After the
device self-checks are complete, the VPAP (or Ramp) screen appears.
Ramp Screen
If your clinician has set a maximum ramp time, the Ramp screen is displayed
after the Welcome screen. On the Ramp screen, you can immediately set a
ramp time. Ramp time is the period during which the pressure increases
from a low pressure to the prescribed treatment pressure. See “Ramp time”
on page 13.
Ramp time can be altered in five minute increments (from OFF to a
maximum ramp time set by your clinician) by using the Up/Down key.
How to Use the Standard Menu
The standard menu allows you to view details about the time used and the
current software version of your VPAP. The Used (time) screen displays the
total number of hours for which the device has been used. It also displays
the number of days the VPAP was used out of the total number of days
available for use.
