[Invasive mechanical ventilation: Update for the pediatrician]

Area of Science:

• Pediatric Critical Care Medicine
• Respiratory Physiology
• Mechanical Ventilation

Context:

• Invasive mechanical ventilation (MV) is a cornerstone of intensive care unit (ICU) management for pediatric patients.
• Acute respiratory failure necessitates ventilatory support to maintain adequate gas exchange.
• Understanding MV principles is crucial for optimizing patient outcomes and minimizing iatrogenic harm.

Purpose:

• To review the fundamental concepts of invasive mechanical ventilation in children with acute respiratory failure.
• To emphasize MV as a therapeutic intervention aimed at restoring ventilatory balance.
• To highlight the importance of safety thresholds in mechanical ventilation to prevent complications.

Summary:

• Mechanical ventilation (MV) in pediatric acute respiratory failure supports the work of breathing and balances ventilatory demand with patient capacity.
• The primary goal of MV is to achieve reasonable gas exchange, not necessarily normalize blood gases, by operating within safety limits.
• Adhering to safety thresholds during MV is critical for limiting the development of ventilator-induced lung injury (VILI).

Impact:

• Provides clinicians with foundational knowledge for safe and effective mechanical ventilation in pediatric critical care.
• Underscores a shift in focus from solely normalizing blood gases to optimizing gas exchange and preventing VILI.
• Contributes to the evidence base for best practices in pediatric respiratory support, potentially reducing morbidity and mortality associated with VILI.
