A Picture Of Healthy Sleep
|
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

High Frequency Coupling (HFC or Stable Sleep) is predominant;
Normal HFC values are greater than 50% of the night |
|
Low Frequency Coupling (LFC or Unstable Sleep) is sparse;
Normal LFC values are 15-20%; Normal ratio of LFC to HFC
is 25% |

Very little LFC |
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. |
