Abstract: Although mechanical ventilation remains central to the management of pediatric respiratory failure, prolonged exposure can predispose critically ill children to multiple iatrogenic complications.Timely and efficient liberation from mechanical ventilation is therefore essential for reducing these risks and improving clinical outcomes.This review examines ventilator liberation through the operational definitions and guidelines proposed by the Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network.Operationally, liberation comprises three key stages: readiness testing, weaning (including the spontaneous breathing trial), and extubation.However, successful liberation requires more than resolution of intrinsic lung and airway pathology and subsequent tapering of ventilatory support.Instead, it represents a complex physiological transition governed by the dynamic balance between respiratory workload and respiratory capacity.Optimal outcomes require comprehensive management of systemic factors, including cardiopulmonary interactions, neuromuscular competence, diaphragmatic function, nutritional status, fluid balance, and sedation depth.By implementing structured, evidence-based practices consistent with PALISI guidance, healthcare providers can increase the likelihood of successful extubation while maintaining patient safety and comfort.This review highlights the need for a standardized approach to weaning that minimizes the duration of mechanical ventilation and improves pediatric intensive care outcomes.
