Sleep Study and Polysomnography Data

This dataset provides detailed, structured results from sleep studies and polysomnography, including key indices, sleep stage distributions, CPAP titration outcomes, and clinical diagnoses. It is designed for use in sleep disorder management, clinical research, and operational analytics, supporting both patient-level tracking and population health studies.

Behind this dataset

Same schema. As many rows as you need.

These 1,000 rows came out of a blueprint — 18 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with

Study ID unique per sleep study
Study type: diagnostic, split-night, CPAP titration, MSLT
Total sleep time (TST) in minutes
Sleep efficiency: (TST / time in bed) × 100
AHI: number of apneas and hypopneas per hour of sleep
AHI severity: normal (<5), mild (5-14), moderate (15-29), severe (≥30)
Oxygen desaturation index (ODI)
Lowest oxygen saturation during sleep
