FDA's MAUDE database holds 210 reports that name the brand "Lifepak 11 Diagnostic Cardiac Monitor" (external cardiac monitor), received between October 1996 and July 2004; the manufacturer given most often on reports is Physio-Control. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, and none 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 (97.6%) and death (2.4%); across all dc-defibrillator, low-energy, (including paddles) reports (product code LDD) death is recorded in 5.7% and malfunction in 89.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are signal artifact/noise (23.8%), display or visual feedback problem (20.5%) and no display/image (10%). The patient problems coded most often are death, resuscitation and asystole. 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."
