Performance Verification and Maintenance
Introduction
This chapter describes how you verify the cardiograph's performance,
explains preventive maintenance, presents patient safety information,
and provides a performance verification checklist.
Performance
Verification
Three procedures make up performance verification: visual inspection
of the cardiograph exterior, execution of Extended Self-test, and
visual examination of an ECG recorded from an ECG patient
simulator.
The performance verification checklist at the end of this chapter
summarizes the steps you should follow to verify the cardiograph's
performance. These are some suggested uses for this checklist:
H Make copies of the blank checklist, then fill out a copy each time
the cardiograph is tested.
n
Attach the printer test output, simulator ECG trace, and error log
printout to the completed checklist and file with the cardiograph's
permanent maintenance record.
Visual
Inspection
Before beginnin, @ the inspection, press the (On-Standby) key to put the
cardiograph in Standby, and unplug the power cord from the wall
outlet. Then inspect the cardiograph for the following:
= Worn or damaged power cord
n
Loose or missing hardware
H Mechanical damage
n
Evidence of liquid spill
n
Worn printer drive gear
n
Worn printer roller
H Corroded or damaged electrodes
H Worn or damaged patient module cable
n
Dirt on the thermal printhead
Replace any damaged or missing items, and clean the printhead and
patient electrodes as necessary. Cleaning instructions are listed
under "Preventive Maintenance" later in this chapter. Connect the
cardiograph to AC power and turn on the AC switch. Observe that
the AC indicator comes on. Turn the cardiograph On and observe
that one or more of the battery indicators light.
