2. Figure 1
Representative recording from the initial sleep study. A 90-second obstructive apnea is shown, during which arterial oxygen saturation decreased to a nadir of 46 percent. From top to bottom, the tracings represent arterial oxygen saturation, airflow detected by a capnograph, thoracic and abdominal volume signals from the respiratory inductive plethysmograph, electrocardiogram (EKG), chin electromyogram (EMG), electroencephalogram (EEG), and electrooculogram (EOG).
