Mode This screen displays the therapy mode setting. Depending on
the therapy device model, you can select CPAP mode, CPAP-
Check (C-Check) mode, Auto-CPAP (Auto) mode, Bi-Level
mode, or Auto Bi-Level (AutoB) mode.
Note: CPAP-Check mode (C-Check) delivers CPAP therapy
while automatically adjusting the pressure level to meet
patient needs over the long term. Every 30 hours of therapy
use, the therapy device evaluates patient obstructive
respiratory disturbance index (ORDI) and increments pressure
± 1 cm H2O if needed. The range of adjustment that can be
made over time is limited to ± 3 cm H2O of the CPAPCheck
pressure setting, in 1 cm H2O increments.
Opti-Start Opti-Start This feature starts an Auto-CPAP therapy session at a starting
pressure that is closer to the previous session’s 90%
pressure, in order to reduce the likelihood of any residual
events at the beginning of a therapy session. You can enable
or disable this feature.
EZ-Start EZ-Start This feature reduces the therapy pressure setting for the first
few days of operation and gradually increases this setting until
the prescription therapy pressure is reached. The initial
pressure will be half of the prescription pressure, but no lower
than 5 cm H2O. After each day of successful use (the session
was greater than 4 hours), the therapy pressure will increase
by 1 cm H2O until the prescription pressure is reached.
From that point forward, the therapy device would operate in
normal CPAP or CPAP-Check mode. If the patient has not
reached their prescription pressure after 30 days of EZ-Start,
then the therapy pressure will increase by 1 cm H2O per day
until the prescription pressure is reached. You can enable or
disable EZ-Start only if CPAP or CPAP-Check mode is
enabled.
A-TRIAL A-Trial This Auto-Trial feature will enable the device to deliver Auto-
CPAP therapy for a selectable number of days of patient use.
You can enable or disable this feature.
A-Trial Days This screen allows you to adjust the duration of the Auto-Trial
feature in number of days. You can set this from 3 to 30 days.
The default is 7 days. This setting only displays if Auto-Trial
mode is available and enabled. When you reach the last
available Auto-Trial period, the text for this selection will
appear in red font.
Auto Min This screen allows you to modify the Auto minimum pressure
setting. You can adjust this setting from 4 cm H2O to the Auto
maximum pressure setting. This setting only displays if Auto-
CPAP mode is enabled or if the Auto-Trial feature is available
and enabled.
