Mediana HeartOn A16 Fully Automatic Defibrillator

Key Features & Benefits

Analysis to shock-ready in 10 seconds or less

The A16 completes its heart rhythm analysis and charges to full capacity in just 10 seconds, ensuring minimal interruption to life-saving CPR. Research indicates that each minute without defibrillation results in a 10% reduction in survival rates.

Same set of pads for adult or child

The A16 uses universal electrode pads with a simple adult/child switch on the device. There’s no need to search for different pads or keys. Just select the correct mode and the defibrillator automatically adjusts the energy level to suit the patient.

Smart enough to work around pacemakers

Many people now live with implanted pacemakers, which can confuse some defibrillators. The A16 recognises and filters out pacemaker signals, ensuring accurate heart rhythm analysis.

This makes it especially reliable in care homes and public spaces, and gives responders peace of mind when treating someone they don’t know.

Built to Withstand Real-World Conditions

With an IP55 rating, the A16 is protected against dust and water jets from any direction. It’s tough enough for outdoor cabinets, leisure centres, sports facilities, and even poolside areas where moisture is unavoidable.

Continuous self-testing for reliability

The A16 constantly monitors its own readiness without any user input:

• Daily checks confirm battery life, pad condition, and overall status
• Weekly tests examine key internal components
• Monthly diagnostics perform a full system health check

This means the defibrillator is always ready when it’s needed most.

Clear voice guidance in multiple languages

The A16 talks the responder through every step of the rescue with calm, clear voice prompts. It comes pre-loaded with English, Welsh, and Polish, the three most commonly spoken languages in the UK.

Languages can be switched instantly at the press of a button, making the device ideal for schools, workplaces, and diverse communities.

Visual guidance when it’s loud or chaotic

Bright LED indicators work in conjunction with the voice prompts to guide the rescuer. The relevant icon lights up red, indicating exactly what to do next and providing visual cues even in noisy or stressful environments.

Automatic event recording for clinicians

Once switched on, the A16 records the entire incident, including voice prompts, background audio, and the full timeline of the rescue.

This information is saved to the supplied SD card and can be shared with emergency departments to support faster, more informed clinical decisions.

Secure and flexible data storage

Event data can be stored and transferred in three ways:

• Removable SD card
• Infrared connection for PC download
• Internal backup memory

If the SD card is missing or full, the device automatically saves everything internally, so nothing is lost.

Imagine a school sports day. A parent or teacher collapses. Any member of staff can grab the A16, switch it on, and follow the spoken instructions. Because the device is fully automatic, the responder doesn’t have to decide when to deliver a shock; the A16 does it for them. This removes fear and hesitation, allowing the rescuer to focus on CPR and saving a life.

Frequently Asked Questions

What type of shock waveform does the Mediana A16 use, and what does that mean to the lay user?

The Mediana A16 uses a Biphasic Truncated Exponential (BTE) waveform, which is the modern standard in defibrillation technology.

In simple terms, this waveform helps restart the heart more effectively and achieves higher survival outcomes with less energy requirement, reducing the risk of heart tissue damage.

What is “impedance compensation,” and why does it matter?

Everyone’s body responds differently to electrical current. The Mediana A16 solves this using impedance compensation.

For layman's understanding, the AED measures the person’s chest resistance and automatically adjusts the shock to deliver the right amount of energy every time. This makes the shock more effective and safe across all body types and conditions.

What maintenance does the Mediana A16 require?

The Mediana HeartOn A16 defibrillator requires very little maintenance, thanks to its comprehensive self-test process. To be sure, you can check the status indicator on the LCD screen on the right hand side of the device and if it reads ‘ok’. The screen also indicates the battery status.

You can also book for an annual professional servicing with DefibSure and get a technical compliance certificate for peace of mind.
