title: Hazard report. Shift checks and semiannual preventive maintenance are important in detecting critical failures in Zoll M series defibrillators.
abstract: The manufacturer-recommended shift check for Zoll M Series defibrillators cannot detect some critical failures that could inhibit defibrillation or pacing. To improve detection of these failures and to limit their impact on patient care, hospitals should perform not only the routine perform not only the routine shift check, but also the twice-annual preventive maintenance procedure recommended by Zoll. Additionally, units exhibiting an error code--even one that appears to resolve itself--should be immediately removed from service and evaluated by the clinical engineering department.
