Figure Lengend Snippet: Patients being treated for severe OSA experienced an acute illness during the treatment periods. Arrows indicate the day when the patients sought medical attention. The illnesses were diagnosed as (A) influenza, (B) bacterial pneumonia, and (C) acute exacerbation of chronic interstitial pneumonia. CPAP machines used were DreamStation AutoCPAP (A and B) and Sleepmate 10 (C).
Article Snippet: 8 Recent typical CPAP machines can record the flow rate measured using a flow sensor at a sampling frequency of 25 Hz (ResMed Sleepmate 10; San Diego, CA) or 5 Hz (DreamStation AutoCPAP) every night for more than 3 years.
