About OSCAR

OSCAR is PC software developed for reviewing and exploring data produced by CPAP and related machines used in the treatment of sleep apnea.

It is a derivative of SleepyHead and reads data from the SD cards of supported CPAP machines and oximeters, presenting detailed graphs, statistics and reports.

Features:

• Detailed daily graphs of pressure, flow, leaks, events and oximetry

• Overview, statistics and printable reports across days, weeks and months

• Data stored in a local SQLite database that other tools can query directly

• Flexible CSV export and profile import/export

OSCAR is not a medical device and is not intended for diagnosis. Discuss your therapy data with your doctor.
