should not be exerted on the finger, especially if the
temperature exceeds 41 ° C.
When using a finger sensor please secure the sensor
and cable. All nail polish (coloured or clear) must be
removed from the measuring finger to obtain usable
data.
To minimize interference (e.g., motion artifacts), the
pulse oximetry values are filtered by digital data
processing. As a result of data averaging and signal
processing, slight delays in the display of the pulse
oximetric values occur. The internal pulse oximeter
works with a time horizon of 4 seconds. By additio-
nally considering the change tendency, the minimum
value of saturation at the end of an apnea is correctly
reproduced. The data is updated at every beat, so
there are no measurable delays due to data refresh
and transmission.
The finger sensor must be attached to the socket
marked with the following symbol:
Please read and understand the instructions accom-
panying the finger sensor.

3.1.5. Sensor for respiratory effort

(not Samoa lite)
The sensors used for recording thorax and abdomi-
nal movement consists of two small rubber pressure
pads that are connected to the device via measuring
hoses. The sensors are inserted into the pockets of
the elasticated effort belts. The thorax belt is applied
at the height of the sternum, the abdominal belt in the
stomach region.
For hygiene reasons and to avoid allergic reactions
the belts should be worn over the clothes.
The effort sensor to monitor thorax movement must
be attached to the socket marked with
effort sensor to monitor abdominal movement must
be attached to the socket marked with
The effort belts are adjustable in size due to the
Velcro fasteners, and should be suitable for most
patients. These belts are however also available in
special sizes.
Note:
Over stretching of the belts may result in poor signals
and possible loss of data.

3.1.6. Sensor for body position

The position sensor integrated in the device displays
information related to the patient's body position
during the study.
For accurate determination of body position, ensure
the device is applied to the patient correctly. The
body positions detected are: Supine, Prone, Left
side, Right side, Upright.

3.2. Preparing for measurement (Ambulatory)

In preparation of an ambulatory study where the
patient will use the device at home, please ensure
the following:
1. Charge the battery: see (Page 25).
2. Start the PC software.
3. Fill out the fields relating to personal data of the
patient in the menu item "Record / Initialize
device" and start the transfer.
4. Connect the device with the USB interface
cable. Socket:
5. A dialogue window will be displayed in order for
the operator to determine the start time and
channel set for recording.
6. The device is now ready for use. The device can
be disconnected from the PC.
Note: remove cable by pulling on the plug - not
on the cable.
3.3. Operating elements of the device with
display
Button:
The device will automatically switch on / off when
connected / disconnected to a PC.

3.3.1. Starting the measurement

The device has an internal clock for timer recording.
If the timer has been programmed, recording will
start automatically at the predetermined time. Up to
eight recordings can be programmed.
Note: If necessary, the measurement can be started
and the
by the patient before the selected start time. To do
this, the on / off switch must be pressed for approx. 2
.
seconds
measurement can then be started manually by
pressing the right arrow key. The measurement starts
as soon as the countdown from 5 to 0 has occurred.
The duration of the measurement is now shown on
the display.
During the measurement, the device's display
switches off automatically while the measurement
continues.

3.3.2. Signal control

After switching on the device with the on / off switch,
the signals of the device (pulse oximetry, breathing
movements, breathing) can be checked on the
display from the start screen by pressing the left
arrow key. The signal control is available both with
and without running measurement.

3.3.3. Stop the measurement

A running measurement can be ended manually. To
do this, keep the on / off switch
symbol is completely red and then no longer visible
in the display.
