FDA's MAUDE database holds 3,049 reports that name the brand "DreamStation BiPAP Pro" (ventilator non-continuous respirator), received between May 2021 and August 2026; the manufacturer given most often on reports is Respironics. Spellings of one product vary from report to report.

108 reports arrived in the 12 months to August 2026, down 87% from 852 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 (77.6%), injury (20.5%) and death (1.9%); across all ventilator, non-continuous (respirator) reports (product code BZD) death is recorded in 1.5% and malfunction in 80.7%.

The device problems coded most often are degraded (99.3%), contamination (2%) and device emits odor (0.1%). The patient problems coded most often are headache, dizziness and cancer. 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."
