If you find yourself in a situation where someone has a cardiac arrest, the best thing to do is call for help. But if you can’t get to them right away, there is another option that can save their life – a portable defibrillator. These units are small and easy to carry, so they can be used anywhere with access to an electrical outlet. They use electricity to shock the heart into a rhythm, which can restart it and potentially save the person’s life. You can get the best portable defibrillators for unforeseen emergencies from Defibs Direct Australia.
