FM1: (FM100 – FM104)
The FM1 provides one output with smooth sinusoidal waveforms focusing on
identification of apnea and hypopnea events.
FM2: (FM200 – FM204)
The FM2 provides more subtle changes in the airflow signal often associated with
flow limitation and UARS.
FM3: (FM300 – FM304)
The FM3 is able to provide a second output channel of snore data, all originating
from one PVDF airflow sensor.
FM4: (FM400 – FM404)
The FM4 provides two separate channels of airflow waveforms, one for scoring
apnea events, and another for scoring hypopnea events.
FM5: (FM500 – FM504)
The FM5 provides the same functionality as the FM4, but includes an additional
snore channel.
