228 medical device reports received by FDA name the brand "Remstar Auto Aflex" (ventilator non-continuous respirator); the manufacturer given most often on reports is Respironics; received from August 2021 to July 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

135 reports arrived in the 12 months to August 2026, up 4400% from 3 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 device problems coded most often are degraded (96.5%), contamination (0.9%) and material integrity problem (0.4%). The patient problems coded most often are headache, dyspnea and cough. 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."
