TECHNICAL DESCRIPTION
The device is a therapy device in the BILEVEL
version for treating obstructive sleep apnea.
Trigger device
The respiration trigger detects the patients efforts
to breath in and out and signals these efforts to the
control device. A flow-based trigger is integrated
which can be set separately for inspiration and
expiration. While the pressure increases during
inspiration it decreases during expiration. In con-
nection with an optimum flank adjustment this
results in a ventilation which is very comfortable for
the patient and which gives the patient the impres-
sion as if the device is following the natural respira-
tion without delay.
NOTE:
During the expiration phase a negative pressure
(vacuum) will not be created.
To generate the necessary pressure, the device is
provided with an electronically controlled blower. In
order to keep the stress for the patient as low as
possible, the blower has been designed with a high
reserve capacity and a quick control response.
The pressure is measured directly in the mask and
constantly controlled by the device. Consequently,
the breathing work for the patient is a easy as pos-
sible. There are two separate tubings in the device.
One is for respiratory air and one is for the convec-
tion air required for cooling the electronics.
In addition to the mask alarm, the device offers
another safety function, the power failure alarm. It
automatically restarts the motor after power resto-
ration.
The device contains a built-in microcontroller which
controls all of its functions. For added comfort an
alarm clock is integrated in the device. Further
comfort functions include a soft start ramp, the
automatic start-stop function and the adjustable
display brightness. While passing through the devi-
ce, the air is heated a little, so that it has a higher
water absorbency. When indoor air is dry in the
heating period, the mucous membranes in mouth
and nose may become particularly dry. This is
unpleasant and may even cause infections in
exceptional cases. For that reason, a therapy might
require air humidification.
AquaDROP et, a clip-on humidifier is available as
accessory for the device. If necessary, just click the
humidifier onto the device. Remove it by pressing
its locking key.
The heater levels are set in the heater menu. The
selected heater level is displayed as a figure in the
display of the device while the humidifier heating is
switched on.

AquaDROP et operating instructions or contact
