Performance Verification and Maintenance
1Introduction
This chapter describes how to verify the cardiograph’s performance, explains preventive
maintenance, presents patient safety information, and provides a performance verification
checklist.
1Performance Verification
Several procedures make up performance verification: visual inspection of the
cardiograph exterior, execution of Extended Self-test, visual examination of an ECG
recorded from an ECG patient simulator, and system safety tests using a safety analyzer.
A Performance Verification matrix which appears at the end of this section specifies the
tests and inspections which must be performed following servicing of the PageWriter
cardiographs. The Performance Verification test results must be recorded on
Customer Service order records
Make copies of the matrix. Fill out a copy each time the cardiograph is tested. Attach the
printer test output, and simulator ECG trace to the completed matrix and file with the
cardiograph’s permanent maintenance record.
If any of the performance verification tests fail, refer to Chapter 4, Troubleshooting.
