SENSOR FOR MEASUREMENT OF MANDIBULAR MOVEMENT 

 

The  sensor  for  mandibular  movement  measurement  is  a  distance 
sensor  which  permits  observation  of  mandibular  movements.  The 
signal given by this sensor is known as Jawac, short for "Jaw Activity".

 

Observing and analyzing mandibular movements during sleep allows 
not  only  to  identify  the  different  sleep  disturbances  such  as  mouth 
breathing,  snoring,  apneas  (central,  obstructive,  and  mixed)  and 
hypopneas, but also to detect conditions of upper airway resistance 
(UARS).

 

It is recommended to become acquainted with the characteristics of the 
Jawac signal before using the recorder. If need be, contact your distributor 
or  the  manufacturer  who  will  tell  you  where  to  find  the  necessary 
documentation.

 

NASAL CANNULA 

 

Nasal  cannulas  are  used  to  assess  airflow  from  nasal  pressure 
measurement. They must be directly connected to the corresponding 
protruding  endpiece  on  the  flow  sensor  module,  connected  on  the 
auxiliary input of Brizzy

+

.

 

 RESPIRATORY MOTION SENSOR

 

  incorporates  an  accelerometer  to  measure  a  respiratory 
motion signal comparable to that of a chest or abdominal belt.

 

PULSE OXYMETER 

 

The Xpod module from Nonin measures the blood oxygen saturation 
level  (SpO2),  the  pulse  frequency,  and  the  plethysmographic 
waveform. Only oximetry sensors from Nonin should be connected to 
the module.

 

 

BODY POSITION SENSOR 

 

The  recorder  is  equipped  with  an  integrated  position  sensor.  This 
sensor measures the patient's position via a 3-axis accelerometer.
