This document provides information about Basic Life Support (BLS) training. It defines BLS as emergency care provided to anyone experiencing cardiac arrest, respiratory distress, or airway obstruction. BLS training teaches skills like CPR, AED use, and relieving airway obstructions. The document emphasizes the importance of BLS training, as cardiac arrest is a leading cause of death but is often reversible if treatment is provided within minutes. However, most laypeople lack proper knowledge of BLS procedures. For this reason, hands-on training from professionals is crucial to prepare individuals to use skills like chest compressions and rescue breathing correctly during emergencies.
