580 medical device reports received by FDA name the brand "Level 1 Hotline Fluid Warmer 390" (warmer thermal infusion fluid); the manufacturer given most often on reports is Oakdale; received from May 2021 to May 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

11 reports arrived in the 12 months to August 2026, down 80% from 56 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 (100%); across all warmer, thermal, infusion fluid reports (product code LGZ) death is recorded in 0.7% and malfunction in 96.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are fluid/blood leak (29.5%), device alarm system (9.5%) and leak/splash (9.3%). The patient problems coded most often are urethral stenosis/stricture. 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."
