1.4.4.6 BODY POSITION AND ACTIVITY
The Sleep&Go records information about the patient’s body position
and actigraphy. Both sensors are place inside the Sleep&Go device,
so no external accessory is needed.
1.4.4.7 SNORING SENSOR
Apart from the snoring signal obtained from the nasal cannula
you may also use a piezoelectric snoring sensor (ref. 06346)
to detect the patient’s tracheal sounds during sleep. The
piezoelectric snoring sensor can be plugged into the connector
labeled as “Aux”, if you’re not using the limb movement sensor.
Also, you may connect the sensor in any of the channels provided
by the ExG module (optional).
The snoring sensor is placed on the throat of the patient and it
generates a signal in response to the vibration produced during
snoring. The piezoelectric sensors are based on the movement
produced by the vibrations and not on the sounds. Therefore
they cancel artefacts related to external noise. The snoring signal
is converted into analogical voltage which can be measured.
To place a piezoelectric snoring sensor, follow these steps:
• Tell the patient to imitate a snore while you place your fingers,
slightly off-centre, upon the throat. Try to
select a point where the greatest vibration
related to the snoring sound is produced.
•
Do not place the sensor directly over the
larynx.
• Place the sensor with the flattest part in
contact with the skin and secure it with
surgical tape.
•
Insert the snoring sensor connector into
the corresponding input of the Sleep&Go
(“Aux” connector or any connector in the
ExG module).
