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.
