Frequently asked questions
Is the Defibtech Lifeline AUTO operation fully automatic?
Yes, the Defibtech Lifeline AUTO AED (Model DDU-120) is a fully automatic external defibrillator. This design is intended to greatly simplify the rescue process:
- The device automatically analyzes the patient’s heart rhythm.
- If a shock is advised, the AED automatically delivers the electrical shock without requiring the rescuer to press a shock button.
This automatic operation eliminates the need for user decision-making during the critical shock delivery phase.
Does the AED provide clear voice guidance?
Yes, the Defibtech Lifeline AUTO AED is specifically engineered for simplicity and provides comprehensive, clear guidance for all rescuers, including those who are untrained.
The guidance system utilizes both audio and visual cues to ensure a smooth rescue process:
- Clear Voice Prompts: The unit delivers simple, step-by-step audio instructions that guide the rescuer through the entire procedure, from pad application to heart rhythm analysis.
- Fully Automatic Operation: This model automatically analyzes the heart rhythm and delivers the electrical shock if required, removing the need for the user to push a shock button and eliminating guesswork.
- Visual Reinforcement: Brightly lit progress lights and visual text indicators reinforce the voice prompts, displaying critical statuses such as “analyzing” and “do not touch patient.”
- CPR Pacing: An integrated audio metronome provides pacing assistance to help maintain the correct rate and rhythm for chest compressions, adhering to AHA/ERC protocols.
Does the battery offer long-term readiness?
Yes, the Defibtech Lifeline AUTO AED is engineered for reliability, offering long-term readiness via disposable (non-rechargeable) Lithium/Manganese Dioxide battery options.
