Visual inspection of the device and accessories
for obvious damage which could result in
mechanical failure.
•
Testing all hose connections are air tight.
•
Testing the thorax and abdominal sensors for
leaks.
•
Checking the display LEDs.
•
Testing the pulse and SpO2 finger sensors and
carrying out a plausibility test (timed pulse test
using).
•
Testing the battery capacity.

MiniScreen 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 unit via the flow prong. The
built in microphone detects the sounds which are
then electronically analysed. Therefore additional
microphones are not required.
