Preparation and Safety Precautions

Initiate by confirming there is no connection to a patient. Ensure adequate lighting and a stable surface. Position the device on a secure bench, alongside gathering essential items like the maintenance log, a defibrillator analyzer or simulator, and extra batteries.

Status Assessment

Inspect the readiness indicators, which may include status lights, icons, or audible cues. Many models automatically conduct diagnostics; if the device is not marked as “ready,” halt operations and refer to the operator’s manual.

Self-Test Procedure

Activate the device to allow a power-on self-test. Cross-check that the clock, voice prompts, display screen, buttons, and speakers are functioning correctly.

Power Source Evaluation

Review the battery status for expiration, fitment, and charge level across all compartments. Replace batteries if any alerts appear or if they exceed their recommended service life.

Electrodes and Accessories Examination

Confirm that electrode packaging remains intact and within the expiration date. Ensure all connectors remain clean, with cables undamaged. Maintain an additional set of electrodes on hand.

Energy and ECG Evaluation

Utilize an endorsed defibrillator analyzer or ECG simulator for testing. Properly connect paddles or therapy cables, then execute an energy delivery test. Compare the results to established tolerances and verify ECG acquisition capabilities.

Device Monitoring and Logging

For models like the R/X Series, generate a printout, check event logs, clear any fault codes, execute audio prompt tests, and affirm “ready” status indicators.

Maintenance and Organization

Disinfect the device exterior using approved wipes. Confirm mounting suitability, inspect the carry case, scissors, razors, barrier mask, signage, and visibility of device location.

Documentation and Issue Escalation

Log all findings, confirming whether the device passes or fails the test. If problems persist, remove the defibrillator from service and contact biomedical support or ZOLL for further assistance.

For swift assessments of any defibrillator, conduct a visual readiness check, perform a power-on self-test, and examine pads and battery conditions. Conduct analyzer-based functional tests per specific policy, adding ECG simulation, printing/log review, and alarm evaluations for ZOLL monitors or defibrillators.

Troubleshooting Common Issues

Field teams often encounter defibrillator challenges during routine checks or urgent deployments. When dealing with Zoll models, it is crucial to first conduct a thorough visual assessment. Ensure all accessories, the status indicator, and device configuration comply with the product manual standards. Consistently log any persistent defibrillator issues using designated site procedures before proceeding with a return process.

Power/Battery Concerns

A low readiness icon signals the need for a battery pack swap. Clean the contacts meticulously, use only approved power supplies, and observe the readiness heat levels. It's important to carefully document any unusual behavior noticed.

Electrodes/Adhesion

Regularly check pad expiry dates and replace any dried pads promptly. Ensure hair is shaved, skin is dry, and pad edges are pressed firmly. Route leads away from moisture-prone areas to maintain effective adhesion.

Self-Test Alerts

When self-checks fail, reseat modules, and reinsert memory cards. Perform a power cycle and verify the configuration checksum against service notes to address such alerts efficiently.

ECG Interference

To mitigate interference, reduce motion and stop vehicle vibrations. Keep defibrillator cables separate from radio equipment, use fresh pads, and monitor signal quality closely on the display.

No Shock Advised

If clinicians identify a shockable rhythm, confirm correct pad placement and full contact. Continue CPR as outlined by established protocols and reassess the situation after further analysis.

Date/Time Drift

Set the clock accurately, align with the appropriate timezone, and sync with hospital record systems to keep event logs consistent for audits.

CPR Feedback

Where applicable, calibrate sensors, change pucks, and inspect cables diligently. Maintain depth and rate targets within established prompts.

Physical Damage

Cracked cases and torn leads are criteria for immediate retirement. Avoid fluid exposure, and if ports are loose or keys sticky, arrange for qualified service promptly.

Should issues persist beyond these interventions, withdraw the unit from service and contact Zoll technical support or consult an accredited biomedical team. Stay informed about recalled accessories or software advisories impacting Zoll devices by reviewing FDA notices and AHA program guidance. Escalate persistent defibrillator issues through internal incident reporting channels.
