This apnea database was collected during the DREAMS project, to tune, train and test our automatic detection algorithms.
It consist of 12 whole-night PSG recordings coming from patients with sleep apnea syndrome and annoted by an expert in respiratory events (central, obstructive and mixed apnea and hypopnea).
In order to facilitate future research and performance comparision, we decided to publish these data on Internet. Be simply aware that this DREAMS Apnea Database of University of MONS - TCTS Laboratory (Stéphanie Devuyst, Thierry Dutoit) and Université Libre de Bruxelles - CHU de Charleroi Sleep Laboratory (Myriam Kerkhofs) is under terms of the Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0) License.

Data collected were acquired in a sleep laboratory of a belgium hospital using a digital 32-channel polygraph (BrainnetTM System of MEDATEC, Brussels, Belgium). They consist of 12 polysomnographic recordings coming from patients with sleep apnea syndrome. Two EOG channels (P8-A1, P18-A1), three EEG channels (CZ-A1 or C3-A1, FP1-A1 and O1-A1), the submental EMG, the ECG , the nasal air flow (NAF) and the abdominal (VAB) and thoracic (VTH) inductive plethysmography were recorded. The standard European Data Format (EDF) was used for storing. The sampling frequency was 200Hz. These excerpts were annoted in respiratory events (central, obstructive and mixed apnea and hypopnea) by an expert. Criteria used were those of the American Academy of Sleep Medicine (AASM). The corresponding whole-night recordings were also previously scored in sleep stages according to the Rechtschaffen and Kales criteria.
|Name||Sampling frequency||Age||apnea/hypopnea index||Recording duration (hh.mm.ss)||Nr. of hypopnea scored by the expert||Nr. of obstructive apnea scored by the expert||Nr. of central apnea scored by the expert||Nr. of mixed apnea scored by the expert|
Three files are available per excerpt:
