474 medical device reports received by FDA name the brand "PHILIPS HeartStart FRx" (automated external defibrillators non-wearable); the manufacturer given most often on reports is Philips North America; received from May 2023 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
301 reports arrived in the 12 months to August 2026, up 102% from 149 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 (97.3%), injury (1.5%) and death (1.3%); across all automated external defibrillators (non-wearable) reports (product code MKJ) death is recorded in 1.7% and malfunction in 96.8%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are failure of device to self-test (67.7%), failure to power up (11%) and failure to run on battery (5.9%). The patient problems coded most often are cardiac arrest and superficial (first degree) burn. 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."
