A comprehensive Polysomnography masterclass aimed to consolidate knowledge of sleep physiology and technology and refresh concepts required for Certification in Sleep Science examination. Facilitated by expert speakers, participants will learn what’s normal, what’s not, how to interpret it all, and when to act. Explore key phenomena seen in PSG, including Cheyne-Stokes respiration, phase disorders, catathrenia, PLMD, and selected cardiac rhythms. Diversify your clinical toolkit with practical insights into PSG setup and signal interpretation topics; Amplifier types, A/D conversion, practical explanation of filters, biocalibration, oximetry, 10-20 accuracy, and EOG features. Sharpen your sleep staging skills with a focus on sleep stage transitions, effects of hypnotics on EEG, transient phenomena, and nuanced application of scoring rules. Differentiate key differences in paediatric sleep: including AHI thresholds for childhood OSA, developmental milestones in sleep spindles, and how hypnograms evolve with age.
