3.1.4. Sensor for oxygen saturation and pulse
frequency
A pulse oximeter has been integrated into the Mini-
Screen Pro for the purpose of measuring oxygen
saturation and pulse frequency.
When using a finger sensor, please use the Velcro
wrist/armband to secure the sensor and cable. The
use of adhesive tape to secure the sensor may result
in allergic reactions to the patient, adhesive residue
damaging the sensor, loss of data. Please ensure
that blood circulation at the point of measurement is
not affected by the manner in which the sensor has
been secured.
All nail polish (coloured or clear) must be removed
from the measuring finger to obtain usable data.
Please read and understand the instructions accom-
panying the finger sensor.
3.1.5. Sensor for thorax and abdominal
movement
The sensors used for recording thorax and abdomi-
nal movement consists of small rubber pressure
pads that are connected to the MiniScreen Pro via
measuring hoses. The sensor for recording thorax
movement comprises of two pressure pads whereas
the sensor for abdominal movement contains only
one. 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 clothes .
The red connector of the thorax sensor needs to be
attached to the red connector and the black
connector of the abdominal sensor needs to be
attached to the
black connector of the device.
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:
Overstretching 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 MiniScreen Pro
displays information related to the patient’s body
position during the study.
For accurate determination of body position, ensure
the MiniScreen Pro is applied to the patient correctly.
The body positions detected are: Supine, Prone, Left
side, Right side, Upright.
3.1.7. Sensor for leg movement
To diagnose restless or periodic leg movements
(restless leg), the MiniScreen Pro can be equipped
for each leg with a sensor and internal recording soft-
ware (optional). The device then enables continuous
recording of leg movements and associated analysis
results in the report.
Attaching the leg sensor :
All commonly available types of electrodes with
1.5mm safety plugs can be used for both bipolar
EMG channels. To connect the electrodes to the
device the splitter box is used. The
yellow marked
connecting plug of the splitter box needs to be
plugged into the
yellow socket on the MiniScreen.
For application and cleaning of the electrodes please
refer to the manual of the manufacturer.
For long time electrodes a very careful preparation of
the skin is necessary!
3.1.8. Sensor for ECG
The supplied ECG cable (optional) is compatible with
all commonly available adhesive electrodes and can
be used as consumables.
Attaching the ECG electrodes:
The red marked connecting plug of the EEG
electrode cable needs to be plugged into the red
socket on the MiniScreen Pro.
Important: The ECG is not suitable for a differential
cardiac diagnosis!
3.1.9. Sensor for Snoring (external)
Additionally to the internal snoring microphone an
external microphone can be used to obtain the
snoring sound. For adapting the snoring microphone
please refer to the manual of the sensor.
The blue marked connecting plug of the microphone
needs to be plugged into the blue socket on the
MiniScreen.
