Abstract

The Sleep-Bench dataset is a collection of clinical polysomnography (PSG) recordings from Stanford Sleep Clinic. It consists of 17.467 PSG recordings spanning 163,650 hours. The dataset is accompanied by a codebase for benchmarking models in the Sleep-Bench GitHub repository.

Background

The Sleep-Bench dataset has been used to develop and systematically evaluate sleep foundation models (SleepFM) resulting in prediction of future disease onset directly from PSG data.
The dataset contains canonical information on sleep including AHI and annotated sleep stages. Additionally there are labels for 13 outcomes with onset time and censoring, ideal for prediction tasks.

Methods

The dataset comprises 6 channels of electroencephalography (EEG) (C3-M2, C4-M1, O1-M2, O2-M1, FP1-M2, FP2-M1), electroculography (EOG) (E1-M2, E2-M1), electromyography (EMG) (Chin (avg(L−ctr,R−ctr))), Leg(RAT−LAT)), echocardiogram (EKG) (EKGL - EKGR), and respiratory channels (Chest (thoracic effort), Abd (abdominal effort), Nasal (nasal airflow), Oral(oral airflow),SpO2 (oxygen saturation)). All signals were resampled to 128 Hz after appropriate filtering and derived from data in the Human Sleep Project.

Data Description

The Sleep-Bench dataset includes 17.467 PSG studies conducted on 12,794 distinct patients

Sleep stages were annotated by certified sleep technologists as part of routine clinical care, according to the American Academy of Sleep Medicine (AASM) manual for the scoring of sleep. Stages were annotated in 30 second contiguous intervals, and include: wakefulness, (W) non-REM stage 1 (N1), non-REM stage 2 (N2), non-REM stage 3 (N3), and rapid eye movement (REM) sleep.
AHI is noted for all subjects
