We found 163 models of X SERIES by Zoll Medical Corporation in the FDA's device registry (GUDID). Together they are named in 6,915 adverse event reports in the FDA's MAUDE database, received between Jul 31, 2015 and Sep 30, 2026 — classified as 164 deaths, 6 injuries, 6,743 malfunctions.
The most frequently reported specific device problem is “Failure to Power Up” (1,618 reports).
Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.
