What is Basic Life Support?

Basic life support (BLS) is a set of life-saving techniques designed to provide immediate care to someone injured or experiencing a life-threatening medical emergency.

\

  • BLS consists of a few basic steps, which include assessing the patient, performing cardiopulmonary resuscitation (CPR), delivering simple first aid, and using an automated external defibrillator (AED).
  • BLS is meant to provide necessary care until professional medical help arrives and should never be used as a substitute for immediate, professional care.
  • Basic Life Support is an invaluable skill that can save the life of someone in distress and make a huge difference when providing medical care in areas where advanced care is unavailable.


The guidelines of Basic Life Support are regularly updated to reflect the most current evidence available. To ensure their knowledge remains up-to-date, all those certified in BLS must renew their certification every two years. Healthcare professionals are typically familiar with the BLS guidelines; however, they must obtain certification to refresh their skills in accordance with the ever-evolving, evidence-based protocols of the American Heart Association.

Basic Anatomy and Physiology

Anatomy and physiology are the basic sciences that support the practice of any health profession. A thorough understanding of how the heart, lungs, brain, and cells perform in our body is essential for healthcare providers to understand the workings of the human body and to develop safe, effective, and individualized treatment plans for their patients.

 

  • The heart, lungs, and brain are critical organs in the body that work together to ensure good health.
  • The heart pumps oxygenated blood from the lungs to the body's cells, and returns deoxygenated blood back to the lungs.
  • The lungs then exchange carbon dioxide for oxygen to supply the body with fresh oxygenated blood.
  • The brain coordinates and works through the entire process, controlling various aspects of the heart and lungs' functions.
  • The heart, lungs, and brain are connected in many intricate ways to ensure that each function properly.
  • Without them, our bodies would struggle to maintain the necessary physiological balances needed to stay alive and healthy.
