PBLS stands for Pediatric Basic Life Support, which is a set of actions performed during cardiac arrest or respiratory failure in children and infants. There are various synonyms for this term, including "Pediatric Cardiopulmonary Resuscitation (CPR)," "Pediatric Advanced Life Support (PALS)," and "Pediatric Emergency Life Support (PELS)." These terms are used interchangeably, but they have slightly different meanings. PALS involves more advanced techniques, while PELS refers to rapid recognition and immediate action in emergency situations. Whatever the term, it's crucial to know the correct procedure for PBLS to save a child's life. Regular training and practice can help healthcare providers and caregivers become proficient in these life-saving techniques.
