OVERVIEW

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common disorder, in which upper airway resistance is increased during sleep due to upper airway dilator muscle relaxation and airway narrowing. It is a common disorder and a recognized public health problem, affecting roughly 2-4% of adult male and 1-2% adult female population. It is still under-diagnosed and believed to be linked with severe cardiovascular diseases, including hypertension, chronic fatigue, metabolic disorders, daytime sleepiness, etc.

Additionally, recent studies in neurophysiology link brain strokes with some abnormal variances and change of patterns in oxygene saturation (SpO2) in the blood, due to (possible) damage in the brain, especially in the stem.

This package contains two sets of data including real heart rate and SpO2 measurements throughout multiple timezones (awake or asleep) for a total of 118+55 unique patients of normal, stroke, and stem stroke classes. The data are of complete-signal registration in full resolution, so that it can be used for thorough signal processing (e.g. spectral analysis), feature extraction and classification for computer-aided diagnosis (CAD).

The sources of the datasets were created in collaboration with the people of Acute Stroke Unit, Dept of Neurology, Eginition, School of Medicine, National Kapodistrian University of Athens (NKUA/UoA), Greece.

These datasets have already been used in various publications describing OSAHS characterization. Detailed description and related conclusions can be found at:

AVAILABLE FILE FORMATS

The datasets are available in the following formats (included):

*.xls    : MS-Excel/LibreOffice native spreadsheets
*.asc    : space-separated plaintext spreadsheets
*.mat    : Matlab/Octave native data file (workspace)

These data formats are equivalent, i.e., they contain the exact same sets of data. Normally, at least one of them should be compatible with any major programming platform (e.g. Matlab, Octave, R) or any native programming language for arbitrary handling (e.g. C, Java).
