Warning
The device and Effort Belt should be worn over clothing.
Caution
Use only Zephyr supplied Effort Belt sensors.
Other sensors may cause inaccurate measurements
or performance.
Note
Before use, carefully read the Effort Belt’s directions
for use.
NASAL CANNULA
The Nasal Cannula measures nasal airflow and snoring.
The Nasal Cannula is an applied part.
It features a dual lumen cannula with air filters. This ensures
the airflow from each nostril is measured independently which
prevents signal inaccuracies when airflow is interrupted from
either nostril during the night.
The air filters prevent transmission of moisture and
contaminants to and from the MATRx plus Recorder.
Warning
The Nasal Cannula is for single patient use only.
Caution
Use only Zephyr supplied Nasal Cannulas.
Other sensors may cause inaccurate measurements or performance.
