The Basics of Ventilator Waveforms [PDF]

open access: yesCurrent Pediatrics Reports, 2021
Knowledge of ventilator waveforms is important for clinicians working with children requiring mechanical ventilation. This review covers the basics of how to interpret and use data from ventilator waveforms in the pediatric intensive care unit.Patient-ventilator asynchrony (PVA) is a common finding in pediatric patients and observed in approximately ...
