Semi-Automatic Defibrillators

About Semi-Automatic Defibrillators

Discover our range of semi-automatic defibrillators (AEDs), designed to deliver fast, reliable life-saving support in every location, such as workplaces, public spaces, schools, healthcare settings, and many more.

How semi-automatic defibrillators work

There are two types of AEDs: semi-automatic and fully automatic. A semi-automatic AED will advise the first responder when the shock is required, so the user can administer it by pressing the button. These devices will still give straightforward instructions, similar to the fully automatic AED, on when to stand clear and when to push the shock button.

Semi-automatic AEDs provide the first responder with complete control over the shocks, allowing them to check everything is in order beforehand, and generally have a faster time to shock due to the responder having to initiate it themselves.

AED brands you can rely on

Our semi-automatic defibrillators from trusted manufacturers, including Philips, Zoll, Mindray, Cardiac Science, HeartSine, Defibtech, Mediana, Vivest, and CU Medical (iPAD), provide intuitive voice prompts and dependable performance in a Sudden Cardiac Arrest (SCA) emergency.

Defibrillator options

Not sure if this is the right fit? Take a look at our fully automatic defibrillators instead, which shock the patient automatically once a rhythm is detected, or browse our refurbished defibrillators for other budget-friendly options.

Replacement pads & batteries

Every AED relies on in-date pads and a charged battery to work when it’s needed. Our replacement pads and batteries are available for a diverse range of defibrillator models and brands.

Defibrillator cabinets & cases

A defibrillator is only useful if it can be found quickly. Browse our defibrillator cabinets for indoor and outdoor storage, including alarmed and heated units to protect your unit year-round, as well as add-ons to complete your installation and carry cases to provide additional protection during transport.

Training courses

Confidence matters as much as life-saving equipment. Book one of our on-site defibrillator familiarisation or basic life support training courses, carried out at your premises by a qualified instructor, or purchase one of our training defibrillators.
