Infant Polysomnography: Arousal Identification and Scoring Reliability

Infant and Pediatric Polysomnography

Polysomnography (PSG): Indications, Technique & Sleep Scoring

Electroencephalographic (EEG) activity in wakefulness and in sleep in humans was initially described in 1928. The earliest overnight sleep studies were performed in the 1930s using a polygraph to record EEG activity and electro-oculograms (EOG) on paper. Major milestones in the history of sleep medicine include the identification of rapid eye movement (REM) sleep in 1953, the description of nor...

Comparison of Manual and Automated Scoring Techniques in Polysomnography

Methods: The sleep recordings of 120 patients with obstructive sleep apnoea (OSA) suspicion who underwent PSG at ear nose and throat clinic of Akdeniz University Hospital between January and June 2013 were retrospectively analysed. Patients were divided into 4 groups according to the apnoea-hypopnea index (AHI): AHI<5 (normal), AHI 5-15 (mild OSA), AHI 15-30 (moderate OSA) and AHI>30 (severe OS...

Characteristics of the infant arousal response.

Arousal is considered to be an important response to a life-threatening stimulus. Recently, it has been shown that the infant arousal response to an elevated inspired CO2 level occurs as a sequence of events involving presumptive brain stem responses before awakening (A. Lijowska, N. Reed, B. Chiodini, and B. T. Thach. Am. J. Respir. Crit. Care Med. 151: A151, 1995; A. S. Lijowska, N. W. Reed, ...

Arousal Responses during Overnight Polysomnography and their Reproducibility in Healthy Young Adults.

STUDY OBJECTIVES Arousal intensity and heart rate (HR) response to arousal during polysomnography (PSG) vary considerably between patients with sleep disorders. Our objective was to determine the range of these arousal characteristics in healthy young adults and whether they are consistent on repeated testing. DESIGN Post hoc analysis of 56 preexisting PSG files recorded from 28 healthy adult...
