1 Introduction

1.1 Concept

WhaleTeq DFS100 is designed for AED field tester. AED (Automated External Defibrillator) is a life-saving medical device that delivers defibrillation upon identifying and analyzing the ECG of a resuscitationneeded patient. Because AEDs are installed in public areas where they can be reached before ambulance arrival, the majority of AEDs rely on one-time batteries and requires only minimal training compared to hospital-use defibrillators. Ensuring the functionality of AEDs periodically becomes widely accepted around the world, and DFS100 is the ideal tool to conduct such a regular inspection.

1.2 Applications

WhaleTeq DFS100 is a compact field tester, functioning as an ECG signal simulator and defibrillation energy guarantee equipment for AED regular maintenance.

For ECG patterns simulation, DFS100 simulates NSR (Normal Sinus Rhythm) as well as other arrhythmias that may need AED defibrillation. Arrhythmia convert combination (ECG waveform before vs. after defibrillation) is also available.

For energy guarantee, DFS100 allows User to customize the pass/fail criteria of the delivered defibrillation energy. To ensure the durability of DFS100, protection against multiple defibrillation is implemented. (DFS100 should be used to analyze defibrillation energy at the interval of at least 60 seconds)

5 PC Software Operation

5.1 Software Function Introduction

The DFS100 PC Software is solely for customized settings. It does not include testing functions.

• A. Default Pattern When On: User can choose from VT (Ventricular Tachycardia), VF (Ventricular Fibrillation), or NSR (Normal Sinus Rhythm) as the default playing pattern when turning on DFS100.

• B. Return To Initial ECG Pattern: When using ONE-TIME TEST mode , User has the option to enable the “Auto Return to Initial ECG Pattern” function, which does so upon 30 seconds after receiving defibrillation.
  Note: If User doesn’t enable the “Auto Return to Initial ECG Pattern” function, User will need to manually switch the pattern from NSR to VT or VF if needed for the next inspection.

• C. Joule Threshold: Depending on different models of DUT (AED), the delivered defibrillation is different. DFS100 allows User to selfdefine the passing criteria of the defibrillation. If the joule of the defibrillation equals to or is higher than this value, the AED Discharge LED lights green; otherwise, lights red.
  Note: User can set the parameter from 40 to 360 Joules.

• D. Auto Off: DFS100 will automatically be turned off after being idle for a certain time. The default value is 3 minutes.
  Note: User can set the time from 3 to 10 minutes.

• E. Check for Updates: Click to see if the latest version of firmware and/or software has been released. Please note that the USB cable used for firmware upgrade must be file-transferrable.

• F. About: Check the software version and the device function introductions.

6 Standalone Operation

6.1 One-Time Test (Convert) ⇆

In this mode, the test starts immediately upon DFS100 being turned on, and it simulates the ECG pattern of a resuscitated-needed patient.
Ensure the AED and DFS100 are connected properly via the interface cable. Turn on both DFS100 and the AED, and follow the AED instructions. The default setting of DFS100 is sending VT to the AED. After the AED delivers defibrillation shock, DFS100 shows the pass/ fail of the defibrillation energy by lighting different LED colors for 30 seconds.
Note: If the test passes, the LED lights green. If the test fails, the LED lights red.
At the same time, DFS100 simulates the patient having been resuscitated by changing the ECG pattern to NSR.

6.2 Continuous Arrhythmia Test ♻

In this mode, DFS100 continuously sends user-selected arrhythmia to the AED.
Ensure the AED and DFS100 are connected properly via the interface cable. Turn on both DFS100 and the AED, and follow the AED

instructions. The default setting of DFS100 is sending VT to the AED. After the AED delivers defibrillation shock, DFS100 shows the pass/ fail of the defibrillation energy by lighting different LED colors for 30 seconds.
Note: If the test passes, the LED lights green. If the test fails, the LED lights red.
Then, User may connect DFS100 to the other AED for the next test. The test starts without User pressing any button on DFS100.

7 Calibration and Validation

It is recommended to get DFS100 calibrated annually. Calibration and validation both require traceable equipment. Steps for Calibration/ Validation methods are available upon request. Please contact Whaleteq for more details (See section 13).

8 Troubleshooting

1. If after the AED defibrillation shock, and the DFS100 “Discharge” LED does not light up, check the AED interface cable connection.
2. If User is certain that the AED defibrillation energy matches its spec, but the “Discharge” LED lights red, check the PC software setting (section 5.1 (C)) to ensure the joule threshold is set correspondingly.
3. When DFS100 “Battery” LED blinks red, change the battery at User’s earliest convenience.

9 Cautions

1. Follow AED instructions during testing with DFS100.
2. Follow the color code and / or labeling when connecting DFS100 and the AED via the AED interface cable.
3. When DFS100 is in use, the face containing LEDs and buttons must face up to allow ventilation.
4. To allow ventilation, DFS100 should be used to analyze defibrillation energy at the interval of at least 60 seconds.
5. USB cable used for firmware upgrade must be file-transferrable.
6. Battery, whether one-time use or rechargeable, must be included in DFS100 for accurate energy measurement.
7. When Battery LED blinks red, the Discharge LED may dim and blink at a faster frequency. This is a warning to change the battery as soon as possible in order to ensure accurate test results.
8. USB Port cannot be used to charge the battery.
9. For best performance, rechargeable battery capacity is recommended to be 800 mAh or above.
10. When not in use for a longer period, remove the battery from DFS100 to ensure a longer lifespan of the battery.
