Volume guaranteed? Accuracy of a volume-targeted ventilation mode in infants

摘要

Objectives Volume-targeted ventilation (VTV) is widely used and may reduce lung injury, but this assumes the clinically set tidal volume (V-Tset) is accurately delivered. This prospective observational study aimed to determine the relationship between V-Tset, expiratory V-T (V-Te) and endotracheal tube leak in a modern neonatal volume-targeted ventilator (VTV) and the resultant partial arterial pressure of carbon dioxide (PaCO2) relationship with and without VTV.
