Chapter 1 Maintenance Tests This chapter describes the procedures for routine testing of the AED Pro® unit. A test typically consists of multiple steps, each of which requires a pass/fail rating. For each step, perform the specified action and then verify that the expected results occur. If all expected results occur, assign a “Pass” rating to the step; otherwise, assign it a “Fail” rating. This chapter includes the following inspection and test procedures: • “1.0 • “2.0 • “5.0 9650-0309-01 Rev.
CHAPTER 1 MAINTENANCE TESTS Preparations for Testing • Gather the required equipment listed in the next section. • Perform all the steps within each test procedure in the order specified. If testing results indicate that the battery pack must be replaced, you will need a fully charged spare battery pack.
Physical Inspection 1.0 Physical Inspection Use this procedure to ensure that the unit shows no signs of damage or excessive wear. Tools Needed None. Test Setup None. Test Procedure Observe the following: Pass Fail 1.1 Is the unit clean? 1.2 Are all signs of wear reasonable and not excessive? 1.3 Are the front panel and housing undamaged and free of cracks? 1.4 Are input connectors clean and undamaged? 1.
CHAPTER 1 2.0 MAINTENANCE TESTS Preventive Maintenance Test Use this test to verify that the AED Pro unit is working properly and ready for use. For an alternative test using the AED Pro simulator, refer to the AED Pro Operator’s Guide. Note: To verify that the delivered energy for the first, second, and third shocks corresponds to the unit’s preconfigured adult energy levels, use the ZOLL Administration Software (ZAS) to obtain the current configuration of the unit.
Preventive Maintenance Test Test Procedure Test 2.1 Action Expected Result(s) Turn on the AED Pro unit. ; UNIT OK ; ADULT PADS ; CHECK RESPONSIVENESS (or CHECK PATIENT) ; DON’T TOUCH PATIENT, ANALYZING ; TREATMENT ADVISED (or SHOCK ADVISED) ; DON’T TOUCH PATIENT ; PRESS FLASHING TREATMENT BUTTON (or PRESS FLASHING SHOCK BUTTON) Note: Some AED Pro units are configured to start with CPR; therefore, these prompts will not be heard. 2.2 Press the Shock button (first shock).
CHAPTER 1 MAINTENANCE TESTS Test Action Expected Result(s) 2.3 Press the Shock button (second shock). • Analyzer indicates a defibrillator discharge at the configured second-shock energy level (120, 150, or 200 joules) ±15%. Note: If your AED Pro unit is not configured for stack shocks, skip to test 2.5. ; Pass Fail N/A TREATMENT DELIVERED (or SHOCK DELIVERED) • An updated shock count appears on the display. 2.4 Press the Shock button (third shock).
Preventive Maintenance Test Test Action Expected Result(s) Pass Fail N/A Turn off the AED Pro unit. Set the analyzer to NSR (normal sinus rhythm). 2.5 Turn on the AED Pro unit. ; UNIT OK ; ADULT PADS ; DON’T TOUCH PATIENT, ANALYZING. ; NO TREATMENT ADVISED (or NO SHOCK ADVISED) These three prompts are optional: — OPEN AIRWAY — CHECK BREATHING — GIVE TWO BREATHS 2.6 Lift the puck that is attached to the universal adapter cable.
CHAPTER 1 MAINTENANCE TESTS Test Action Expected Result(s) 2.7 Increase the vertical motion of the puck (about 2 to 3 inches or 5.0 to 7.6 cm). • Unit emits spaced tones as a guide for performing chest compressions at the proper rate. On the display screen, make sure the bar on the chest compression gauge extends into the area between the lower two lines.
Battery Check 3.0 Battery Check Use this procedure to ensure that the battery shows no signs of damage or excessive wear. Tools Needed None. Test Setup None. Test Procedure Test 4.0 Action Expected Result(s) Pass Fail N/A 3.1 Open battery door and verify that the battery has no signs of visible damage. 3.2 For a sealed lead acid battery, verify that the battery is not older than 18 months (if it is older than 18 months, ZOLL recommends that you replace the battery).
CHAPTER 1 5.0 MAINTENANCE TESTS Manual Self-Test Use this test to initiate the unit’s self-diagnostic procedure, which verifies the following: • Battery usage since last reset. • Defibrillation electrodes are properly connected. • ECG signal acquisition and processing electronics are functional. • Defibrillator charge and discharge circuitry (operational at 2 joules) is functional. • Microprocessor hardware and software are functional.
Chapter 2 Troubleshooting This chapter describes technical issues commonly encountered during routine maintenance or after a malfunction of the AED Pro unit and recommends steps to solve the problem. This chapter also lists AED Pro error log messages that indicate the unit requires technical service.

Wait None. until the unit issues the prompt PRESS FLASHING SHOCK BUTTON before pressing the button. ; PLUG IN DEFIB CABLE Note: This prompt appears if an ECG None. cable is connected, but the unit is not configured for ECG monitoring. — Check the cable and replace if necessary. ; RELEASE LEFT SOFTKEY — Release the softkey. None.
CHAPTER 2 TROUBLESHOOTING ECG Monitoring Troubleshooting Table 2-2 lists common issues with ECG monitoring and their associated corrective action. Table 2-2. ECG Monitoring Issues Symptom Corrective Action ; Ensure that the ECG cable is connected to each electrode and to the unit. CHECK ECG ELECTRODES or ; Ensure that the ECG electrodes are making good contact with the patient and are not dried out. ATTACH ECG ELECTRODES Replace the ECG electrodes. Replace the ECG cable.
Defibrillator Troubleshooting Defibrillator Troubleshooting Table 2-3 lists common issues with defibrillation and their associated corrective action. Table 2-3. Defibrillator Issues Symptom Corrective Action Defibrillator does not charge. (Semiautomatic mode only) The patient’s ECG rhythm is not shockable because it is not either ventricular fibrillation (VF) or wide-complex ventricular tachycardia (VT), or is VF with amplitude less than 100 μV.
CHAPTER 2 TROUBLESHOOTING AED Pro Error Log Messages The AED Pro unit records internal errors in an error log, which you can retrieve by using a Windows-based personal computer with ZOLL Administration Software (ZAS). To retrieve the error log, follow these steps: Step Action 1 Turn off the AED Pro unit. 2 Start the ZOLL Administration Software (ZAS) on the computer.
