3. Recording measurement data using the
MiniScreen Pro unit
3.1. Sensors
3.1.1. Sensors for flow and snoring noises
The detection of patient flow is determined by the
use of a nasal flow prong that transmits the pressure
signal to an internal pressure transducer of the
device. The flow prong can be easily applied by the
user and will have no adverse affect on the quality of
sleep. The use of a flow prong also eradicates the
problem where adhesive sensors cannot be used.
(i.e.: patients with beards). In addition the flow prong
is an economical choice of sensor as it is commonly
available.
No additional sensor is required for respiratory and
snoring detection. Respiratory sounds are trans-
mitted to the MiniScreen Pro via the flow prong. The
built in microphone detects the sounds which are
then electronically analysed. Therefore additional
microphones are not required.
Due to the high sensitivity of the internal pressure
transducer, the MiniScreen
Pro is capable of
measuring and recording ultra fine pressure differen-
ces associated with patients who mouth breathe.
In order to connect the flow prong, ensure the
connector of the prong attaches into the
blue
connector of the device.
The flow prong should be used in accordance with
the manufacturer’s instructions.
Warning:
The flow prong is intended for single patient use. No
attempt should be made to clean or use the flow
prong the more than once. Multiple use can result in
cross infection!
3.1.2. Thermistor sensor for breathing
Additional to the flow prong a Thermistor can be
used to measure the breathing. Please also observe
the instructions accompanying the sensor.
The brown connector of the Thermistor needs to be
attached to the brown connector on the MiniScreen.
3.1.3. Sensor for CPAP/Bilevel-pressure
When performing measurements on a patient under-
going CPAP therapy, an adapter hose is used instead
of the flow prong.
The connector of the CPAP adapter needs to be
attached to the
blue connector on the MiniScreen.
