pressure-limited ventilation
Ventilatory strategy that caps airway pressure to prevent barotrauma while accepting variable tidal volumes in pediatric patients.
Full Definition
Pressure-limited ventilation is a protective ventilation strategy commonly employed in pediatric anesthesia where the ventilator is set to not exceed a predetermined peak inspiratory pressure. This approach prioritizes lung protection over consistent tidal volume delivery, allowing tidal volumes to vary based on lung compliance and airway resistance. It is particularly important in infants and children due to their increased susceptibility to ventilator-induced lung injury and the rapid changes in compliance that can occur during pediatric procedures.
Usage
Usage note: Hyphenate when used as a compound modifier.
