19 Maintenance Operational Check

Operational Check
Operational Checks should be performed at regular intervals to supplement the hourly, daily, and
weekly Automated Tests executed by the MRx. Automated Tests provide adequate assurance that the
device is in a functional state of readiness. Operational Checks supplement the Automated Tests by
verifying therapy cables, the ECG cable, paddles, audio, the Charge and Shock buttons, Therapy
Knob, and Compression Sensor, along with replicating the Weekly test. Operational Checks also
notify you if the battery, NBP module, or CO
2
module need calibration.
WARNING Be sure the HeartStart MRx is not connected to the patient when performing an Operational Check.
NOTE It is important to establish a schedule for conducting Operational Checks, as well as for checking
supplies and accessories associated with the HeartStart MRx. This will ensure that the device is ready to
monitor and deliver therapy. The Operational Check is run with a battery installed to reflect optimal
operating conditions for defibrillation. The device automatically disconnects AC/DC power.
NOTE If you have the Pacing option, test external paddles using the Weekly Shock test. You must run
Operational Check with a pads cable in order to pass the Pacer test.
Prior to performing the Operational Check, ensure that the paddles (if tested) are secure in their
pockets and that the PCI LEDs are not lit. Should the LEDs light, adjust the paddles in their pockets.
If the LEDs continue to light, clean both the adult and pediatric paddle electrode surfaces.
At completion of the Operational Check, the message Operational Check Passed is displayed if all of the
tests pass.
If any test fails the message Operational Check failed is displayed along with one (or more) of the
following messages, depending upon the severity of the failed functionality:
• Service device.
• Replace battery.
• Replace Compression Sensor.
• Replace Pads cable.
• Replace Paddles cable.
• Replace Therapy cable.
• Replace ECG cable
You must fix the problem and successfully run the Operational Check to clear the failure.
NOTE If the HeartStart MRx is equipped with multifunction defib pads only and does not have a paddle tray,
you cannot test paddles during an Operational Check. To test paddles, you must have a test load. Run
the Weekly Shock Test, delivering the shock into the test load. See “Weekly Shock Test” on page 219.
