What distinguishes Basic Life Support (BLS) from Advanced Life Support (ALS)?

The distinction between Basic Life Support (BLS) and Advanced Life Support (ALS) primarily revolves around the level of care provided and the types of interventions that can be performed. BLS is foundational care aimed at maintaining vital functions, and it typically includes techniques like cardiopulmonary resuscitation (CPR), airway management, and using automated external defibrillators (AEDs). These interventions are generally non-invasive and rely on basic skills that can be learned by laypersons and responders with basic medical training.

In contrast, ALS encompasses a wider range of interventions that require more advanced training and typically include invasive procedures. This may involve administering medications, performing advanced airway management techniques (like intubation), and using monitoring equipment to assess cardiac rhythms. The focus of ALS is on treating life-threatening conditions through more complex and invasive methods that go beyond what is covered in BLS.

Thus, the correct answer highlights that BLS includes first aid and essential life support procedures while ALS adds advanced skills, invasive interventions, and the use of medications. This clear distinction underscores the progression of care from basic support to more advanced life-saving techniques in emergency medical settings.
