Reporting Problems with External Defibrillators
Prompt reporting of adverse events can help the FDA identify and better understand the risks associated with medical devices.
If you suspect a problem with an external defibrillator, we encourage you to file a report with the FDA.
Health Care Professionals and Consumers:
We encourage you to file a voluntary report through MedWatch, the FDA Safety Information and Adverse Event Reporting program.
User Facilities:
Health care personnel employed by facilities that are subject to FDA's user facility reporting requirements should follow the reporting procedures established by their facilities.
Device Manufacturers:
Device manufacturers must comply with the Medical Device Reporting (MDR) regulations.
