A BLS (Basic Life Support) certification is a qualification that trains individuals to provide immediate care to people who are experiencing life-threatening health emergencies. The training typically covers skills like CPR (cardiopulmonary resuscitation), using an AED (automated external defibrillator), and other basic emergency procedures to help sustain someone’s life until professional medical help arrives. It is often required for healthcare professionals and is also beneficial for anyone who wants to be prepared to handle emergency situations.
