TECHNICAL DESCRIPTION
GENERAL REMARKS
For all devices of the TREND II series the following
characteristics apply.
To generate the necessary pressure, the device is pro-
vided 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 capac-
ity 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 as easy as possible.
There are two separate tubings in the device. One is for
respiratory air and one is for the convection air required
for cooling the electronics.
In addition to the mask alarm, the device offers an-other
safety function, the power failure alarm. It automatically
restarts the motor after power restoration.
The device contains a built-in microcontroller which
controls all of its functions.
A quartz alarm clock further adds to the comfort when
using the device. Further comfort functions include
a soft start ramp, the automatic start-stop function
