Comparison of sleep staging by polygraph and color density spectral array.
Color Density Spectral Array (CDSA) is a new technique that uses the fast Fourier transform and color graphics to provide a display of frequency, power, and time. CDSA sleep records provide an overview of sleep architecture as well as quantitative+ EEG data. To validate this technique, overnight sleep records from five patients were independently staged from polygraph recordings and overnight CDSA records. Observed agreement between the two techniques was 85-92% for approximately 1,100 epochs per night.
