Ambulatory polysomnography using a new programmable amplifier system w on-line digitization of data: technical & clinical findings

  [ 86 votes ]   [ Discuss This Article ]
By Drewes AM, Nielsen et al. • www.ProHealth.com • May 12, 1996


A new system for polysomnographic recording at home is
presented. It consists of a 12 to 24-channel amplifier system
with direct digitization of the polygraph signals using a
portable computer. Sampling frequency, amplification and
filter settings can be defined by the user, and the signals
are evaluated at bedside. Technical testing proved a high
signal/noise ratio, linear amplification and a good signal
quality. Clinical testing of the first 100 recordings showed
that they were acceptable for conventional sleep scoring in
98 cases. A comparison of two consecutive recordings was done
in 9 healthy subjects and 11 patients with rheumatic
disorders. Using conventional sleep staging, only a slight
"first night effect" (FNE) was demonstrated in the sleep
architecture. Power spectral analysis using autoregressive
modeling demonstrated only a difference of power between the
2 nights in the beta (14.5-25 Hz) band. In conclusion, the
usability and technical advantages make the system very
suitable for ambulatory recordings and only a minimal FNE
should be considered when results are evaluated.
