Simple evaluation of SDB:
- Normal sleep is ≥50% HFC
- Unstable sleep is <50% HFC and an LFC/HFC ratio of >25%
- OSA has >15% LFC
- Complex Sleep Apnea has >2% LFC narrow band values
RemLogic™ CPC Module
A Picture Of Complex Sleep Apnea
Full View:
- Loss of HFC (Stable Sleep); Complex SA is associated with HFC band values <50%
- LFC (Unstable Sleep); Complex SA is associated with elevated LFC narrow band values >2%
90° View
- LFC (Unstable Sleep) is increased
The 90° view of the CPC spectrogram shows the distribution of peaks in the LFC frequency range of 0.0 to 140 mHz along the X-axis. Time is displayed along the Y-axis with the start of recording near zero.
