Your BLS certification — or recertification — comes around fast, and the pressure is real. As a healthcare professional, you're expected to deliver high-quality CPR, operate an AED, and clear an obstructed airway correctly, often against a timer. The BLS Quick Study Guide helps you prepare with confidence by turning Basic Life Support into clear, organized material you can actually remember. Written for busy healthcare providers, this independent study guide reflects the concepts in the 2025 CPR & ECC guideline updates — so you review current technique, not outdated material. WHAT'S INSIDE Complete adult, child, and infant coverage — compressions, ventilations, airway management, and AED use for every age group Updated 2025 concepts — the revised infant chest-compression technique, the current choking (foreign-body airway obstruction) sequence, opioid-overdose response with naloxone as an adjunct, and the single Chain of Survival 50 practice questions — a 25-question pre-test and a 25-question post-test, each with complete answer keys and detailed rationales Clear decision algorithms — original, simplified flowcharts for adult, child, and infant emergencies Quick Reference Cards — at-a-glance summaries for fast review right before your course or skills check Plain-language explanations with KEY POINT, WARNING, and PRACTICE TIP callouts that flag what matters most A self-evaluation skills checklist to rehearse and sharpen your technique WHO IT'S FOR Nurses, physicians, EMTs, paramedics, respiratory therapists, medical and nursing students, and any healthcare professional preparing for a BLS certification or recertification course — or anyone who wants a clear, current refresher on lifesaving skills. AN IMPORTANT NOTE This is an independent study aid. It is not produced by, affiliated with, sponsored by, reviewed by, or endorsed by the American Heart Association (AHA) or any other resuscitation organization, and it is not a certification. It does not replace an official, instructor-led BLS course or hands-on skills testing. Use it to study and review — then complete a formal course to become certified, and always follow your employer's protocols and current local guidelines. Prepare smart. Review with confidence. Walk in ready.
