    DEVICE EVAL SUMMARY: DEVICE EVAL OF MONITOR SN (B)(4) HAS BEEN COMPLETED. THE REPORTED PROBLEM (SERVICE CODE 102) WAS CONFIRMED. UPON INVESTIGATION RESISTOR R45 WAS OPEN ON THE C/A BOARD, WHICH CAUSED THE SERVICE CODE 102. THE CAUSE FOR THE OPEN R45 RESISTOR WAS A BROKEN LEAD ON HIGH-VOLTAGE CAPACITOR C22 ON THE DEFIBRILLATOR BOARD. THE ROOT CAUSE FOR THE BROKEN LEAD ON C22 COULD NOT BE POSITIVELY IDENTIFIED, BUT THE DAMAGE LIKELY RESULTED FROM THE MONITOR IMPACTING A HARD SURFACE. ROOT CAUSE ANALYSIS OF SIMILAR EVENTS FOUND THAT EXCESSIVE STRAIN ON THE PRINTED CIRCUIT ASSEMBLY (PCA) FROM SEVERE IMPACT CAN CAUSE FRACTURED SOLDER CONNECTIONS. A MECHANICAL DESIGN CHANGE TO REDUCE THE PCA STRAIN WAS APPROVED BY FDA ON 12/20/2012. IMPLEMENTATION BEGAN ON 01/21/2013. RESULTS WILL BE MONITORED. NO ADVERSE EVENT RESULTED FROM THE BROKEN LEAD ON C22. THE PT RECEIVED A REPLACEMENT MONITOR.
