Basic Life Support (BLS) is one of the most vital emergency care skills anyone can learn. Across communities, workplaces, schools, and public spaces, emergencies can occur without warning. In those crucial first minutes, the actions of bystanders often determine whether a person survives. Understanding Basic Life Support in UK contexts is therefore not just for healthcare professionals, but for everyone who wants to be prepared to save a life. This blog explores how Basic Life Support can save lives, the key principles behind it, and the essential practices that make it effective. By building awareness and confidence, more people can act decisively when it matters most.
