INTENDED USE
The VECTOR et CPAP is intended for treating
obstructive sleep apnea in patients with a weight of
30 kg and higher.
The device generates a continuous positive airway
pressure in order to keep the upper respiratory
tract unobstructed.
The device is not suitable for being used with
patients who need artificial respiration. This therapy
device is no life-preserving system.
The treatment pressure is applied through a
ventilation mask. This ventilation mask must be
provided with an exhalation valve in order to ensure
that the exhaled air is discharged. Do not wear the
ventilation mask while the therapy device is turned
off because, otherwise, you might rebreathe
exhaled air. Please also follow the manufacturer's
instructions on use of the ventilation mask.

TECHNICAL DESCRIPTION
The VECTOR et CPAP is a therapy device for trea-
ting obstructive sleep apnea.
In addition to the conventional CPAP-mode, the
device offers in FLEXLINE-mode a pressure
increase during inspiration and pressure reduction
during expiration which is proportional to the
individual breath flow.
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
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
another 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 and the adjustable display brightness.
While passing through the device, the air is heated
a little, so that it has a higher water absorbency.
When indoor air is dry in winter, the mucous
membranes in mouth and nose may become
particularly dry. This is unpleasant and may even
cause infections in exceptional cases. For that rea-
son, 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 in the display
of the device while the humidifier heating is
switched on.
For more information please see your
AquaDROP et operating instructions or contact
your specialized dealer.

NOTES PRIOR TO FIRST USE
Never turn the device on if you kept it in a very cold
environment. Wait for approx. 1 hour until its
temperature compensation is completed.
Regularly check the air filter cassette and regularly
exchange it as described on page 18. Never use
the device without air filter.
Clean your mask system regularly and check all
accessory parts, particularly the therapy tubing, the
mask and the head gear. We recommend that you
wash your face before going to sleep, in order to
remove fat and cosmectics from your skin. This
increases the service life of the mask and helps to
prevent irritations of the skin.
Make sure the measurement tube is unobstructed
at all times. Avoid ingress of water into the
measurement tube during cleaning. If water
droplets should have accidentally entered the
measurement tube they must be carefully and
thoroughly removed.
Please strictly observe the following setup
instructions:
• Do not place the device in the vicinity of a
heating source. Air circulation – particularly
that below and behind the device – must not
be impaired by furniture, curtains or cushions.
• Set up the device next to your bed.
Place it on a firm and flat surface of your
bedside cabinet.
• During mobile use, the device must also be
placed on a firm and flat base, which must
have an edge to protect the device from fal-
ling off.

ALARM FUNCTIONS
POWER FAILURE
If a power faiure at night would go unnoticed as a
result the patient would breathe used air from the
therapy tubing all night. To avoid this the device is
equipped with an alarm mechanism that warns you
with a 5 seconds delay if power or a fuse fail at
night. You will be woken up with an acoustic signal
so you can take the mask off your face and breathe
fresh air.
The alarm is turned off by pushing the operating
button. After power supply is re-established the
motor starts automatically and the display will show
the following message:
CHECK POWER FAILURE WARNING
NOTE:
To check the power failure alarm, the device must
have been connected to the power cord and tur-
ned on for at least half an hour.
Use the device with running blower and then pull
the power plug out of the wall socket. Now the
acoustic warning signal should sound. Check once
a month if the signal sounds long enough (refe-
rence value: at least 3 minutes).
After pushing the operating button or turning on the
power supply again the signal will stop.
MASK ALARM
This alarm function is activated only if the automatic
function is turned off. If the mask has slipped off
your face or if the tubing is pulled off the device,
the device is not turned off automatically, but emits
a visual and audible alarm. However, this additional
safety function requires that you turn the device on
in the evening and off and in the morning with the
operating button (ON/OFF).
CHECK MASK ALARM
Use the device with running turbine in the manual
mode (automatic mode OFF). The mask is open
but not applied to your face. After a short time, an
audible signal is emitted.
