Mediana HeartOn A15 AED Built for Every Setting

When every second matters, you need a defibrillator you can trust. The Mediana HeartOn A15 AED is a semi-automatic defibrillator offering fast adult-to-paediatric mode switching, intuitive voice and visual prompts, and robust IP54-rated protection. From schools and care facilities to workplaces and semi-exposed marine sites, it’s engineered to deliver confidence and compliance in critical situations.

What Makes the A15 Stand Out

  • Instant paediatric mode, no pad change required
  • Auto-on lid activates immediately upon opening
  • Voice commands and LED symbols guide step-by-step
  • Self-testing system with battery/pad expiry alerts
  • Lightweight at 2.65 kg with clear LCD status display
  • IP54 dust and splash resistance plus 1 m drop-tested design

Designed for Public Access and Protected Marine Environments

While not fully waterproof, the HeartOn A15 is suitable for coastal facilities, ferries, lifeboat stations, and marine vessels when placed inside a weatherproof IP66-rated cabinet. This makes it a strong candidate for MGN 297(M) and PFEER-aligned offshore safety plans.

Reliable, Cost-Effective, and Built to Last

The HeartOn A15 offers:

  • Up to 5 years standby life
  • 200 shocks or 10 hours of usage time
  • 2-year electrode pad shelf life
  • Easy-to-access SD card data logging
  • Compliance for CQC, MHRA, and PUWER inspections

We also offer compatible replacement batteries and electrode pads and provide crucial information in our AED Maintenance Guide.

Best Use Cases for the Mediana HeartOn A15

  • Education & Childcare – Instantly switches to child mode
  • Marine Facilities – Portable and splash-resistant in sheltered areas
  • Public Access Spaces – Designed for ease of use by lay responders
  • Healthcare & Clinics – Fully compliant for regulated environments

Why Schools and Childcare Settings Trust the A15 AED

When it comes to protecting younger lives, the Mediana HeartOn A15 offers a major advantage: rapid paediatric readiness with no pad swap required. Unlike other defibrillators that need separate child electrode pads or additional configurations, the A15 features a switch that instantly adjusts shock levels to a paediatric-safe setting.

This simple toggle eliminates delays during high-stress events, which is crucial in schools, nurseries, and sports centres where staff may not be medically trained. The device retains the same pads and battery for both adult and child use, reducing maintenance complexity and ongoing costs.

Combined with its intuitive voice prompts, LED guidance, and IP54 durability, the HeartOn A15 stands out as an ideal fit for safeguarding both students and staff.

Real-world events have shown the importance of rapid AED access in education. In one instance, a student suffered a cardiac arrest during a school cricket match, highlighting the urgent need for on-site defibrillators that are easy to use in paediatric emergencies.

How to Integrate the A15 into Your Emergency Plan

  • Mount in a visible location, preferably inside a cabinet
  • Log regular checks as part of SOPs and staff training
  • Ensure team members are CPR/AED trained.
  • Register your AED with The Circuit for emergency access

Training and Confidence for First-Time Responders

One of the standout benefits of the HeartOn A15 is its user-friendly interface, which significantly lowers the barrier for untrained bystanders. Whether installed in an office, a leisure centre, or a school hallway, this device ensures that first responders with little to no medical background can act quickly and confidently.

The voice instructions and LED light prompts guide the user step-by-step through the rescue process. Switching to paediatric mode is as simple as flipping a switch; no pad swap is needed, saving valuable seconds in child-related emergencies.

To complement its ease of use, we recommend pairing your HeartOn A15 with our training.

Compliance Made Simple for Regulated Environments

Whether you’re preparing for a CQC inspection in a care facility or aligning with PUWER and MHRA requirements in a workplace, the HeartOn A15 streamlines compliance. Its built-in self-test functionality, battery and pad expiry alerts, and LCD status indicator ensure your device is always ready and your checks are easily documented.

The SD card data logging supports post-incident reporting and audit readiness, giving organisations the tools to meet regulatory obligations without hassle. For enhanced compliance, pair the A15 with our AED Maintenance Guide to stay inspection-ready year-round.
