PRODUCT INFORMATION

Defibtech · Semi-Automatic AED

Defibtech Lifeline Semi-Auto AED

A public-access defibrillator with two-button operation, voice prompts through the whole rescue sequence, and a built-in metronome that paces compressions. Semi-automatic means the device advises the shock and the responder presses the illuminated button — the confirmation step some institutional protocols require. Sold with either the standard 5-year battery pack or the high-capacity 7-year standby pack; the battery you choose is a different SKU.

Semi-automatic is a protocol decision, not a feature upgrade. Buy it because your program wants a responder in the loop before the shock, not because it costs less to train.

What's Included by Battery Type

Two battery configurations, each its own SKU. The AED, pads and documentation are the same in both — the battery pack is what changes. Tap the configuration you are buying. Pediatric pads and a carry case are not included in either.

▾Who Carries It

Schools, offices and public venues running a public-access defibrillation program · Employers and facilities that need a device with automatic self-tests and a documented maintenance interval · Training programs and institutions whose protocol specifically calls for semi-automatic operation, so a responder confirms before therapy is delivered.

An AED is a regulated medical device. Placement, medical direction, responder training, pad and battery replacement intervals, and any pediatric use are governed by your program's medical director and by state and local requirements. Confirm your obligations before the device goes on a wall.

FREQUENTLY ASKED QUESTIONS

How does the Defibtech Lifeline SEMI differ from the AUTO version?

The SEMI-automatic Lifeline requires the operator to press an illuminated shock button after the device advises that a shock is appropriate. The AUTO version delivers the shock automatically without requiring any button press. Both deliver identical 150J biphasic therapy. The SEMI is preferred by some organizations that want human operator engagement in the shock delivery decision; the AUTO is preferred where maximum simplicity for untrained bystanders is the priority.

What waveform technology does the Defibtech Lifeline SEMI use?

The Lifeline SEMI uses a biphasic truncated exponential waveform with automatic impedance compensation. This is the most studied biphasic waveform in the AED category, validated across thousands of clinical deployments. The waveform automatically adjusts to the patient's transthoracic resistance to maintain therapeutic efficacy — delivering 150J nominal into a 50-ohm load, with real-time calibration for each individual patient. The device exceeds American Heart Association performance recommendations.

Can the Lifeline SEMI's rescue protocol be updated as guidelines change?

Yes. The Lifeline SEMI supports field protocol updates via data card insertion — the device's AHA/ERC rescue protocol can be updated without returning the unit to the manufacturer. This is a significant long-term value feature: as resuscitation guidelines are periodically revised (typically every 5 years by the AHA), AEDs with fixed protocols can become clinically outdated. The Lifeline SEMI's updateable protocol extends its useful clinical life and protects the investment.

Is the built-in CPR metronome useful for untrained bystanders?

Yes. The metronome provides an auditory beat at the guideline-recommended rate during CPR cycles, helping bystanders without formal training deliver compressions at an appropriate pace. Research shows that untrained bystanders consistently deliver compressions either too fast or too slow without external pacing cues. The metronome addresses this directly, improving CPR quality in the critical period before AED shock delivery or EMS arrival.

What warranty does the Defibtech Lifeline SEMI come with?

The Lifeline SEMI AED unit carries an 8-year manufacturer warranty — one of the longest in the public-access AED category. The standard battery pack carries a 5-year warranty, and adult electrode pads carry a 2-year warranty. This warranty structure significantly reduces the total cost of ownership for public-access AED programs compared to devices requiring more frequent component replacement cycles.
