Technical component of a sleep-deprived/induced EEG or an EEG with time-locked video recording.
What it covers
G541 is the technical component for both a sleep-deprived/induced EEG and an EEG with time-locked video recording (J84).
A sleep-deprived/induced EEG follows more than 4 hours of overnight sleep deprivation, or a sedative/hypnotic given to induce sleep. It must include at least 60 minutes of recording, at least 16 EEG channels and recordings of at least two physiological parameters (J84). An EEG with time-locked video recording must include at least 30 minutes of recording, at least 16 EEG channels, recordings of at least two physiological parameters and a time-locked video recording (J84).
