ZOLL – Defibrillators

In 1952 Paul M. Zoll, M.D was Chief of the Cardiac Clinic at Beth Israel Hospital. He demonstrated that external electrical stimulation of a patient’s chest during cardiac arrest could produce an effective heartbeat.

In 1956he is the first physician to successfully use external defibrillation to regulate heart rhythms in patients. This discovery contributes significantly to the decrease in heart disease mortality.

With technical collaborators, Dr. Zoll develops a way to display the heart’s cardiac electrical activity on an oscilloscopic screen. This includes registering each heartbeat with an audible signal, and sounding an alarm at the onset of cardiac arrest. These developments lead to cardiac monitors and other programs found in modern cardiac care units.

In 1960He discovers that external electrical countershock is effective in terminating supraventricular tachycardia and ventricular tachycardia.

In 2001 the ZOLL AED Plus® was designed in cooperation with the Burlington, Mass. Police Department and hundreds of other first responders and EMS agencies.

FAQs

What is a ZOLL defibrillator?

A ZOLL defibrillator is an automated external defibrillator (AED) designed to treat sudden cardiac arrest by checking a patient's heart rhythm and delivering a life-saving electric shock if required. It guides the user through every step using clear voice and visual prompts, making it safe and simple for untrained bystanders to operate. ZOLL's Real CPR Help® technology also provides real-time feedback on the depth and rate of chest compressions. As an authorised UK distributor, DefibWarehouse supplies both the ZOLL AED Plus and ZOLL AED 3, available in semi-automatic and fully automatic models.

Who makes ZOLL defibrillators?

ZOLL AEDs are manufactured by ZOLL Medical Corporation, a subsidiary of Asahi Kasei Group. Based in the USA, ZOLL is regarded as a global leader in emergency medical equipment and diagnostic technology that help clinicians, emergency services and first responders improve patient outcomes in critical cardiopulmonary conditions.

What is the difference between the ZOLL AED Plus and ZOLL AED 3?

The ZOLL AED Plus features Real CPR Help with simple audio-visual prompts and is known for its CPR-D-padz and long battery life, making it ideal for community and workplace use. The ZOLL AED 3 adds a full-colour touchscreen, ECG display, Wi-Fi connectivity, universal adult/child pads, paediatric switch, and advanced Rapid Shock analysis for faster response. Both use clear instructions, but the AED 3 offers enhanced data features and is suited to higher-traffic or professional settings.

How long do ZOLL AED batteries and pads last?

ZOLL AED batteries have an expected life of up to five years. ZOLL AED Plus defibrillator pads (CPR-D-padz) and ZOLL AED 3 Uni-padz usually require replacement every five years (or immediately after use). Always use genuine ZOLL replacements for safe operation and device readiness.

How to check ZOLL defibrillator is working?

ZOLL defibrillators conduct automatic self-tests daily to verify internal circuits, battery status, and pad connection. Confirm the green status indicator is illuminated and check for any error alerts. Regular visual inspections will support automatic diagnostics and ensure ongoing device readiness.

Are ZOLL defibrillators suitable for untrained users?

Yes, every ZOLL defibrillator is designed for simplicity, delivering step-by-step voice and visual prompts. The integrated Real CPR Help feedback instructs users at each stage, enabling confident use in emergencies; even for those without prior training.

Are ZOLL defibrillators biphasic or monophasic?

ZOLL defibrillators are biphasic using a proprietary technology called Rectilinear Biphasic™ waveform (RBW). A rectilinear biphasic waveform means the shock current flows in one direction and then reverses. Older monophasic defibrillators sent the current one way only and needed more energy to do the job. Biphasic is the standard in modern AEDs because it's effective at lower energy levels and is gentler on the heart. ZOLL AEDs also adjust the shock to suit the person being treated, so an untrained rescuer doesn't need to set anything.

Can I replace ZOLL AED batteries and pads myself?

Yes, ZOLL AED batteries and pads are designed for straightforward user replacement. Simply follow the device’s user manual and always fit genuine ZOLL accessories to maintain safety and optimal performance.

Are ZOLL defibrillators compliant with EU and UK regulations?

Yes. The ZOLL AED Plus and ZOLL AED 3 defib are in compliance with the EU Medical Device Regulation 2017/745 (EU MDR), and are CE/UKCA marked for use in the UK and EU.

Do you provide Zoll AED accessories?

Yes. We stock genuine ZOLL pads, batteries and other accessories. Using genuine accessories helps ensure your ZOLL AED performs safely and reliably when needed.

What is the lifespan of a ZOLL defibrillator?

The overall lifespan of ZOLL defibrillator unit typically lasts 7 to 10 years depending on the specific model and maintenance.
