In emergency medical services, what does "BLS" stand for?

In emergency medical services, "BLS" stands for Basic Life Support. This term refers to the fundamental level of medical care provided to sustain life in emergency situations, especially before advanced medical help arrives. BLS includes techniques such as cardiopulmonary resuscitation (CPR), use of an automated external defibrillator (AED), and relief of airway obstructions. It is essential for first responders, healthcare providers, and laypersons to be trained in these techniques to effectively assist individuals experiencing life-threatening conditions.

Other terms like Basic Lifeguard Services, Biological Life Support, and Broad Life Safety do not correctly encapsulate the formal training or skills associated with emergency medical services. The focus of BLS specifically on life support makes it a critical component in pre-hospital emergency care protocols.
