PALS (Pediatric Advanced Life Support) is an important certification for professionals involved in the pediatric healthcare segment. Infants or children may experience a serious illness, whether in school, at home, or in the hospital. In this regard, PALS algorithms offer systematic instructions to guide the responses taken during critical medical incidents involving children and infants. This protocol is a set of guidelines that assist healthcare workers in handling pediatric emergency cases like cardiac arrest and resuscitation. This article explains the main components of the PALS algorithms.
