Provides unique coverage of Infant Polysomnography (IPSG) as applied to infants over time, starting with preterm and continuing past 6 months post term. The contents cover the fundamentals of polysomnography such as caregiver education, the recording environment, and preparation of the laboratory prior to recording. The book includes a discussion of polysomnography in contrast to a more limited sleep study or pneumogram, directions on how to achieve optimal PSG results in very young infants, reliable techniques for scoring sleep and events, and waveform examples. Using examples from the Collaborative Home Infant Monitor Evaluation (CHIME) experience, the author presents recommendations for data acquisition, recording considerations, monitoring, sleep state and stage definitions, recognition and smoothing, electroencephalographic arousal, and cardiorespiratory patterns and events.
