# OSCAR (Open Source CPAP Analysis Reporter)

Free desktop software that reads your CPAP's SD card and charts every breath, leak and event.

OSCAR is a free, open-source program that imports detailed data from the SD cards of most ResMed, Philips Respironics and other PAP machines. It shows flow-rate waveforms, pressure, mask leak, flow limitation and every apnea or hypopnea event night by night, far beyond the summary numbers in manufacturer apps. CPAP users and clinicians use it to troubleshoot residual AHI, mask leaks and pressure settings. It is not a medical device and does not replace your sleep physician.

Price: Free, open source. Site: https://www.sleepfiles.com/OSCAR/.
