GENERAL INFORMATION
INTENDED USE
BRIZZY+ is a portable sleep recorder made for detecting and assisting in diagnosis of sleep
apnea syndrome and for monitoring its treatment.
It is intended for use by health professionals having basic knowledge of sleep disorders, in
particular of sleep breathing disorders.
The system is simple to use. After having received a short training from a qualified member
of staff, the patient can go back home and install the device himself with the help of the
patient leaflet. Thanks to the automatic wake/sleep discrimination feature, there is no need
to set the time at which the recording should begin.
Furthermore, the software that accompanies the device delivers a high-performance
automatic analysis of the recorded data.
Brizzy+ (NS26 model) records the following parameters :
•Mandibular lowering: mandibular activity presents characteristics which permit
the detection of respiratory events during sleep,
•Mandibular movements: derived from the lower mandible signal, band-pass
filtered signal to display the oscillatory component of the signal,
•Airflow: respiration through a cannula connected to an auxiliary flow sensor,
•Snoring (inspiratory and expiratory): vibratory signal from the nasal cannula,
•Respiratory movements: an accelerometer that measures a respiratory movement
comparable to that of a chest or abdominal belt,
•Oxygen saturation (SpO2): given by the oximeter.
•Pulse frequency: given by the oximeter.
•Plethysmographic waveform: given by the oximeter.
•Body position: indication of the patient’s sleeping position
As an option, Brizzy+ allows the connection of an auxiliary sensor other than the flow sensor,
such as a pneumotachograph for therapeutic monitoring by CPP (Continuous Positive
Pressure).
APIOS – the software – allows displaying the recorded signals, to analyse the data, and to
generate a report, and then helps the operator determine:
•wether the patient suffers from sleep disordered breathing,
•wether the treatment delivered to such a patient needs to be adjusted.
