The following recordings were made using a computerized workstation: multiple channels of the electroencephalogram (central and occipital), two channels of the electrooculogram, two channels of the electromyogram, the oronasal flow (using a thermistor and a nasal pressure transducer), the respiratory effort (using abdominal and thoracic strain gauges), the oxygen saturation (using pulse oximetry), snoring sounds (using a microphone), submental and anterior tibialis monitoring, and body position (20).
The basic recordings included electroencephalogram (F3A2, F4A1, C3A2, C4A1, O1A2, and O2A1), electrooculogram (LOCA2, and ROCA1), chin EMG, electrocardiogram, nasaloral pressure transducer airflow, thermal oronasal airflow, thoracic and abdominal respiratory efforts, oxyhemoglobin saturation, snoring sound, body position, and leg movement.
