Multichannel polysomnographic recording Multichannel polysomnographic recording. The tracings (top to bottom) include four electroencephalogram channels, chin muscle tone movement (submental electromyogram), nasal airflow, thoracic wall movement, abdominal wall movement, end-tidal carbon dioxide, electrocardiogram, pulse oximeter waveform, saturation, and tibial electromyogram. There are multiple episodes of obstructive apnea with associated oxyhemoglobin desaturation depicted in this 2-minute epoch. (Reproduced with permission from Johnson JT, Gluckman JL, Sanders MH, eds.
