AbstractStudies have shown that up to 63% of pediatric intensive care unit patients admitted with acute respiratory or cardiorespiratory illness require mechanical ventilation. Mechanical ventilator support can be divided into three phases: initiation, escalation, and resolution. Noninvasive ventilation is typical during the initiation phase in the management of acute pediatric respiratory failure. The major advancements in the use of noninvasive ventilation involve the emergence of high-flow nasal cannula and how widespread the use of high-flow nasal cannula has become in pediatric critical care practice. When high-flow nasal cannula fails, escalation to continuous positive airway pressure or bi-level positive airway pressure is the next step in respiratory care progression. Careful clinical assessment is necessary to avoid delayed escalation between forms of noninvasive support or escalation to intubation and invasive mechanical ventilation. Advancements in conventional mechanical ventilation are centered on optimizing ventilator settings and customizing monitoring with the overarching goal to reduce complications of mechanical ventilation, such as ventilator-induced lung injury. New mechanical ventilator strategies integrating esophageal pressure monitoring, volumetric capnography, and neurally adjusted ventilator assist help to optimize conventional ventilator support. Nonconventional modes of ventilation in the intensive care unit are high-frequency modes and airway pressure release ventilation. Extracorporeal pulmonary support via extracorporeal membrane oxygenation or paracorporeal lung assist devices provides rescue options when conventional and nonconventional methods fail. During resolution of a course of mechanical ventilator support, reliable weaning strategies and extubation readiness testing are lacking in pediatric critical care. Further, timing of tracheostomy, risk reduction in ventilator-induced lung injury, and decreased sedation requirements in pediatric patients requiring mechanical ventilation in the pediatric intensive care unit are areas of ongoing research.© 2021 John Wiley & Sons Ltd.
