BLS certification stands for Basic Life Support certification, which is a credential that shows the recipient has received training in both single-rescuer and team basic life support skills. BLS generally refers to the type of care that first-responders, healthcare providers, and public safety professionals provide to anyone who is experiencing cardiac arrest or other life-threatening emergencies. BLS certification courses cover essential skills and knowledge needed to provide immediate life-saving care in emergency situations, particularly for healthcare professionals, first responders, and individuals in certain job roles.

BLS certification courses are designed and taught by experts, ensuring that the information provided meets or exceeds local, state, and/or national standards. The American Red Cross and the American Heart Association are two organizations that provide BLS certification courses. BLS certification courses have been developed under the guidance of, and reviewed by, nationally recognized experts from a wide range of scientific, medical, and academic disciplines.

BLS certification courses cover a range of skills, including recognizing life-threatening emergencies, providing high-quality chest compressions, delivering appropriate ventilations, and providing early use of an AED. In addition to the physical skills necessary for providing BLS care to those in need, those working in basic life support also need to have critical-thinking and problem-solving skills and be able to work as part of a team to deliver the best care possible and improve patient outcomes.

BLS certification is often required for healthcare professionals, first responders, and individuals in certain job roles, as it teaches the skills needed to provide life-saving assistance in emergency situations. BLS certification is valid for two years from the date on the certificate, and recertification courses are available for those whose certification is about to expire or has expired within 30 days.
