FDA's MAUDE database holds 299 reports that name the brand "G3 Plus Aed Aha 2010 English" (automated external defibrillator), received between January 2020 and August 2026; the manufacturer given most often on reports is Cardiac Science. Spellings of one product vary from report to report.

7 reports arrived in the 12 months to August 2026, close to the 7 of 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 (99.7%) and injury (0.3%); 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 unable to obtain readings (84.6%), high impedance (10.7%) and battery problem (1%). The patient problems coded most often are no patient involvement. 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."
