FDA's MAUDE database holds 216 reports that name the brand "DreamStation BiPAP AVAPS" (ventilator continuous non-life-supporting), received between January 2022 and August 2026; the manufacturer given most often on reports is Respironics. Spellings of one product vary from report to report.

23 reports arrived in the 12 months to August 2026, down 67% from 69 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (93.1%), injury (6%) and death (0.9%); across all ventilator, continuous, non-life-supporting reports (product code MNS) death is recorded in 3.4% and malfunction in 86%.

The device problems coded most often are degraded (91.2%), contamination (2.3%) and corroded (1.9%). The patient problems coded most often are dyspnea, headache and dizziness. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
