Contraindications
The TREND 300 is for treatment of nighttime sleep
apnea in patient weighing at least 30 kg.
The respiration therapy may be contraindicated for patients with the following pre-existing medical conditions:
This device is not intended for use with ventilatordependent patients.
■
■
■
■
The TREND 300 provides positive airway pressure in
two pressure levels.
This device is designed to be used with nasal breathing
masks equipped with an exhalation port to allow a continuous flow of air through the mask. Do not wear the
mask with the device turned off as rebreating of the air
occurs. Refer to the manufacturer´s instructions for the
mask and exhalation port.
Devices equipped with an AquaTREND accessory
humidifier provide humidification of the air delivered to
the patient.

TREND 300
Bullous lung diseases
Pneumothorax
Extremely low blood pressure
Pneumocephalus or pre-existing CSF leaks or head
trauma.
Acute sinus or middle ear infection may be an indication
to suspend the therapy. Contact your physician if you
have questions about this condition.
Devices equipped with an AquaTREND accessory
humidifier are not intended for use with medications,
aromatic oils or other substances added to the humidifier water.
Not for use with patients whose supraglottic airways
have been bypassed.
Technology of TREND 300
TREND 300 is a respiration BILEVEL therapy unit for
treatment of nighttime sleep apnea. An air humidifier
can be obtained as an accessory.
For the pressure generation TREND 300 has an
electronically controlled blower. In order to keep
the patient's burdening as low as possible the
turbine has been equipped with sufficient power
reserves as well as a fast control circuit.
The pressure control is applied directly in
the breathing-mask. So the breathing musculature
needs not balance out the flow losses of the
breathing air in tube and humidifier.
That means the breathing work is made as
easy as possible.
NOTE:
No negative pressure is been generated during
exspiration phase.
Trigger device
The respiratory trigger recognises the patients efforts to
breathe in and out and transmits them to a control
mechanism.
The trigger mechanism of the TREND 300 has its own
microcontroller to optimise the release of the trigger by
dynamic adjustment of the release criteria to various
sleeping phases.
In conjunction with optimal flank adjustment the patient
experiences a pleasant ventilation which gives him or
her the impression that the unit pursues the natural
breathing mechanisms without any inertia.
TREND 300 has separate air ductings for breathing
air and convection air for the electronics.
The cold temperature technology applied in the power
electronics ensures a low temperature and a long life of
the device.
For the control of all functions TREND 300 has a
built-in microcomputer. The integrated quartz
alarm clock increases the comfort during use
of the device.
The air heats up marginally on passing through the unit
and has a higher water uptake capacity. Particularly in
winter when the room air is dry the mucous membranes
in the mouth and nose can dry out. This is unpleasent
and in isolated cases also leads to infections. Air humidification may therefore also be necessary in conjunction
with respiration therapy.
AquaTREND accessory devices are available which
provide humidification. The humidifier simply clicks into
position and can be removed by pressing the release
button.
Refer to the AquaTREND user´s manual or contact your
dealer for more information.

Hints to be observed before starting
Before operating the device, please pay attention to the
following:
Please pay attention to the following
advices for setting up:
1. Never switch on the device if it has recently
been in a very cold environment. Wait
approximately one hour for temperature
compensation.
1. Never place the device near a heater
or radiator. Make sure the air circulation especially
under and behind the device is not hindered by
furniture, curtains or pillows.
2. Check the filter cassette at regular intervals and
change it regular (see pages 17, 26). Never use
the device without filter cassette.
2. Place the device beside your bed on a firm and even
surface such as a nightstand or bedside table.
3. Clean the mask system regularly, and check the
accessory especially the therapeutic tube, mask
and fixing straps. We recommend to wash the
face before going to bed as skin oils and
cosmetic should be removed.
Thus, the life-span of the mask will be increased
and skin irritations can be avoided.
4. Verify that the measuring tube (smaller tube) is
correctly attached, open and free of moisture or
obstructions. If water enters this tube during
cleaning, take special care to remove it.

Alarm Functions of TREND 300
Power Failure
Wake-up Alarm
Probably you won't notice a power failure at night-time.
As a consequence you would permanently inhale the
exhausted air from the therapy tube. Therefore TREND
300 has an alarm mechanism responding if a power failure occurs at night-time or if a fuse becomes defective.
In this case an acoustic alarm would wake you up
so that you can take off the mask and breathe fresh
air. The alarm can be switched off by pressing the
control key (ON/OFF).
After the end of power failure the turbine of TREND
300 starts again automatically.
For higher comfort TREND 300 has an integrated
alarm-clock. It can be activated and deactivated with
the program keys.
The alarm-clock raises alarm at the pre-set wake time.
If you press the control key once the alarm will stop
for the next five minutes and if you press it twice
the alarm will be totally switched off.
Mask Alarm
This alarm function is active only if the automatic
function is switched off. If at night-time the mask
slips down or the therapeutic tube is pulled off the
device won't switch off automatically but raise an
acoustic alarm. This additional safety function,
however, requires that the device is switched on and
off with the control key (ON/OFF) each morning and
evening.

Date, Time
Date and time of the internal clock can be adjusted. The
internal clock has a built-in battery with reserve power
for 8 years without mains connection. You can adjust
the weekdays (Mo thru Su), day (1 till 31), month (1 till
12), year (00 till 99), hour (00 till 24) and minute (00 till
59). The clock serves for indicating the right date, for
the right function of the alarm-clock and for the exact
recording of current events.
Ramp
After each turbine start the computer of TREND 300
checks whether a softstart-ramp has been programmed. During the time which you have preset the softstart function slowly raises the pressure from 3 hPa
(mbar) up to the pressure prescribed by your physician.
This should ease your falling asleep. Before starting softstart TREND 300 checks the proper fitting of the mask
using the full pressure for the selected time.
Especially if you feel you have not yet got used to the
respiration-therapy the softstart can give you relief.
The delay time of TREND 300 can be adjusted
between zero (in this case the therapeutic pressure
prescribed is instantly given) and 60 minutes (the
therapeutic pressure prescribed is built-up within 60
min).

Functions of TREND 300
Automatic Operation
In case of automatic operation you have only to put on
the mask. As soon as you breathe the turbine of
TREND 300 will be switched on.
If you take off the mask the turbine will be switched off
automatically after a delay time of 5 seconds. During
automatic operation the device also will be switched off
if mask or tube drop off unnoticed at night-time.
That is why TREND 300 optionally offers the function
"Automatic OFF" with mask-alarm.
If you choose this function you must press the CONTROL key (ON/OFF) for switching on the device each
evening and switching off each morning. In this case
you get an acoustic alarm if the mask drops off at nighttime.
Pressure (I-Set, E-Set, I-Slope, E-Slope)
The adjustment of the desired pressures and slopes is
done by the physician who has a special remote control.
Without remote control, however, it is also possible to
change the pressure adjustment of the device provided
that a respective PIN has been programmed. The PIN
will enable the service company to do the respective
work if necessary.
Please, never try to "crack" the PIN.
You should better talk to your physician in case of any
doubt about the pressure prescribed.

Trigger
The trigger sensitivity is adjustable in 5 steps.
Example:
TRIGGER .... 1 (lowest trigger threshold
= highest trigger sensitivity)
TRIGGER .... 3 (medium trigger threshold
* factory adjustment)
TRIGGER .... 5 (highest trigger threshold
= lowest trigger sensitivity)
NOTE:
The adjustment of the trigger sensitivity should ever be
made by your physician.
Brightness
You can adjust the brightness of the display to suit your
needs by selecting between two stages:
■ 100% = maximum brightness, the display is easily
legible also in brightly lit rooms.
■ 50% = minimum brightness, the display is easily
legible in slightly darkened rooms.
In the event of an alarm, the display always switches automatically to 100% brightness for the duration of the alarm.
