Safety information 13
INTENDED USE
The VECTOR et is used to treat obstructive sleep apnea in patients weigh-
ing more than 30 kg.
The device creates continuous, positive airway pressure to keep the upper
respiratory tracts open.
The device is not suitable for use with patients undergoing artificial respiration.
This therapy device is not a life-supporting system.
The therapy pressure is administered via a respiratory mask which must be
fitted with an exhalation valve to ensure that the exhaled air is discharged.
If an AquaDROP et humidifier is connected to the device, the water in
the humidifier must not contain any additives such as medicines, salts,
aromatic oils or other substances.

14 Safety information
CONTRAINDICATIONS
Respiratory therapy may be contraindicated for certain pre-existing
conditions. Therefore, always talk to the physician treating you before
starting the therapy.
Pre-existing conditions include:
• bullous lung diseases
•pneumothorax
•very low blood pressure
• pneumocephalus after open craniocerebral injury or other head injuries
In the event of inflammation of the paranasal sinuses or a middle-ear infec-
tion, it should be checked whether the therapy can continue. Please speak
to your physician about this.

Safety information 15
SIDE EFFECTS
There is the possibility of undesirable side effects occurring with respira-
tory therapy. Reasons for side effects occurring could be unsuitable ther-
apy settings, not using the device properly or not following the cleaning
instructions.
Normally the side effects disappear when the causes have been eliminated.
You will find suitable counter measures for some side effects in the sec-
tion “Troubleshooting” on page 66.
The following side effects may occur during therapy:
• Pain in the nose, the paranasal sinuses and the ears
• Dryness and irritation in the nose and throat
• Nose bleed, runny nose, sneezing, colds
• Irritated or dry eyes
• Reddening of the skin, swelling of the skin and
pressure points in the mask area
• Difficulty breathing, claustrophobia
• Stomach problems because of air accumulating in the stomach
Please contact your physician for an explanation of the causes should
these complaints persist.

TECHNICAL DESCRIPTION
For all devices of the VECTOR et series the following characteristics apply.
To generate the necessary pressure, the device is provided with an elec-
tronically 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.
The device contains a built-in microcontroller which controls all of its func-
tions.
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 absor-
bency. 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 reason, a therapy might
require air humidification.
AquaDROP et a clip-on humidifier is available as accessory for all VECTOR et
devices.
If necessary, just click the humidifier onto the device. Remove it by press-
ing its release button.
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 - User`s manual or
contact your specialized dealer.

POWER SUPPLY
External switched-mode power supply
For mains operation the VECTOR et has an external switching power supply
with a wide input range of 100 - 240 V alternating current (AC), 50 - 60 Hz.
Thus it is possible to connect it to an energy supply anywhere in the world.
.
DC vehicle cable
For mobile use of the VECTOR et, e.g., in a truck or a caravan, it is possible to
operate it with a 24 V direct current (DC). For this you will need the optionally
available DC vehicle cable.
Only use the optional DC vehicle cable to connect the device to a
DC power supply and do not connect the device to a PC while it is
being used.
VECTOR et CPAP
The CPAP device is a therapy device for treating obstructive sleep apnea.
For this purpose the device provides a continuous positive air pressure.
Apart from the conventional CPAP-mode the device offers a proportional
increase in pressure in the FLEXLINE mode to the individual breath flow
during inspiration and a pressure drop during the expiration. This intel-
ligent method of pressure adjustment makes a careful therapy possible.

20 Description of device
VECTOR et AUTO
Within a certain pressure range the device automatically controls the ther-
apy pressure depending on the occurrence of respiratory events (APAP
= Adaptive Positive Airway Pressure). In sleep phases with no events the
therapy pressure is lowered. Starting obstructive events are treated effec-
tively with a slight pressure increase.
For a high therapy comfort the therapy pressure should always be only as
high as necessary and as low as possible.
The device can recognize the following respiratory events:
• Obstructive apnea
• Hypopnea
• Central apnea
• Snoring
• Normal respiration
• Increased airway resistance
The identification of the different respiratory events is achieved via 3 chan-
nels:
1. Measurement of any constriction of the respiratory tract
2. Detection of flow limitations by measuring the flow
3. Detection of snoring with the help of sound detection
The combined analysis of all results facilitates a very precise differentiation
between obstructive and central events.
The device adjusts the therapy pressure according to the detected events
as described below:
•Increase of pressure for obstructive events
• Decrease of pressure for central events and normal respiration
In addition, the pressure increase can be adjusted in 5 levels according to
special requirements and to the individual patient comfort. These settings
are performed by the physician with the help of the PC software TRENDset.
In addition to normal APAP and CPAP mode the device offers the FLEXLINE
mode, a pressure increase which is proportionate to the individual respi-
ration flow during inspiration and a pressure decrease during expiration.
