반응형 미국수면학회aasm4 수면 단계의 판독-7(sleep stage R-1) Stage R1. Score in accordance with the following definitions;Rapid eye movements (REMs): Eye movements recorded in the EOG derivations consisting of conjugate, irregular, sharply peak eye movements with an initial deflection usually lasting Low chin EMG tone: Baseline EMG activity in the chin derivation no higher than in any other sleep stage and usually at the lowest level of the entire recordi.. 2025. 2. 17. 수면 단계의 판독-6(sleep stage N2, N3) Stage N2 4. Continue to score epochs with low-amplitude, mixed frequency EEG activity without K complexes or sleep spindle as stage N2 if they are preceded by epochs containing either of the following and there is no intervening arousal:a.K complex associated with arousal b.Sleep spindle5. Epohs following an epoch of the stage N3 that do not meet criteria for stage N3 are scored as stage N2 if t.. 2025. 2. 15. 수면 단계의 판독-5(sleep stage N2) Stage N2 1.Score in accordance with the following definitionsK complex: A well delineated, negative, sharp wave immediately followed by a positive component standing out from the background EEG, with total duration ≥0.5 seconds, and usually maximal in amplitude when recorded using frontal derivations. For an arousal to be associated with a K complex, the arousal must either be concurrent with th.. 2025. 2. 13. 수면 단계의 판독-4(sleep stage N1) Stage N1 1. Score in accordance with the following definitions Slow eye movements(SEM): Conjugate, reasonably regular, sinusoidal eye movement with an initial deflection that usually laste >500 msec. Slow eye movements may be seen during eyes wake and stage N1. Low-amplitude, mixed-frequency (LAMF): Low-amplitude EEG activity that is predominantly 4-7Hz. Vertex sharp waves (V waves):Sharply .. 2025. 2. 11. 이전 1 다음 반응형
