Evaluation of Cuff Pressure Behavior in Neonates During Mechanical Ventilation Using Endotracheal Microcuff Tubes: An In-Vitro Study on a Neonatal Lung Model

Newborns in neonatal intensive care units are often intubated and ventilated with cuff tubes, e.g. during surgery. During mechanical ventilation with neonatal microcuffs, there is often an unexpected loss of cuff pressure. The aim of this study was to determine how constant the cuff pressure remains during conventional ventilation. A further aim was to investigate the influence of different patient constitutions and the question of whether a fatal drop in cuff pressure can be prevented.
