Defibtech Lifeline Vollautomatischer AED

What is the key difference between the Lifeline AUTO and Lifeline SEMI AED?

The Lifeline AUTO delivers a defibrillation shock automatically when indicated — no button press required. After pads are applied and the device analyzes the rhythm, it will announce a warning to stand clear and deliver therapy without operator intervention. The Lifeline SEMI requires the operator to press the illuminated shock button after the device advises that a shock is needed. Both deliver identical 150J biphasic therapy; the choice affects whether a human confirmation step occurs before delivery.

Is it safe to use a fully automatic AED without medical training?

Yes. The Lifeline AUTO's fully automated sequence is specifically designed for untrained bystanders. The device only delivers a shock when its ECG analysis algorithms detect a shockable rhythm (ventricular fibrillation or pulseless ventricular tachycardia) — it will not shock a patient with a non-shockable rhythm or a conscious patient. Clear voice announcements alert bystanders to stand clear before delivery. The algorithms meet IEC-60601-2-4 and AAMI DF80 standards for sensitivity and specificity in shockable rhythm detection.

Which battery option should I choose — standard 5-year or high-capacity 7-year?

The standard battery (MEDTAC1075) provides 7 years of standby life with 300 shocks or 16 hours continuous operation — ideal for most public-access deployments where extended standby life is the priority. The high-capacity battery (MEDTAC1076) offers 5 years standby with 125 shocks and 8 hours continuous — the 'high-capacity' designation refers to its higher voltage (12V vs 15V) and different chemistry, not necessarily more shocks. The standard battery is the more common choice for wall-mounted public-access deployment.

How does the Lifeline AUTO ensure it is ready for use when needed?

The Lifeline AUTO performs automatic self-tests daily, weekly, monthly, and quarterly. Daily tests verify circuitry and battery status. Weekly and monthly tests include escalating electronic component checks. A battery insertion test runs automatically whenever the battery pack is removed and reinserted. Visual and audible status indicators alert facility staff if any test fails. The device also tests for pad presence daily — confirming that pads are connected before they are needed.

Can the Lifeline AUTO be used on children?

Yes, with the appropriate pediatric pads (model DDP-200P). When pediatric pads are installed and connected, the device delivers reduced therapy of 50 Joules with pediatric-appropriate prompts. Pediatric pads should be used for patients under 8 years of age or weighing less than 55 lb (25 kg). The device should not be used on infants. For facilities that may encounter pediatric cardiac arrest — schools, recreational facilities, family venues — having pediatric pads on hand is strongly recommended.
