FDA's MAUDE database holds 192 reports that name the brand "IntelliVue MX40 2.4GHz" (intellivue mx40 2 4ghz), received between February 2023 and August 2026; the manufacturer given most often on reports is Philips Medical Systems. Spellings of one product vary from report to report.
56 reports arrived in the 12 months to August 2026, up 22% from 46 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 (92.2%), death (6.8%) and injury (1%); across all detector and alarm, arrhythmia reports (product code DSI) death is recorded in 1.5% and malfunction in 90.5%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are no audible alarm (62.5%), no audible prompt/feedback (15.1%) and defective alarm (5.2%). The patient problems coded most often are asystole, bradycardia and cardiac arrest. 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."
