Ventilator variables predicting extubation readiness in extremely premature infants with prolonged mechanical ventilation: A retrospective observational study.

Background: The current generation of neonatal ventilators enables periodic storage of set, measured, and calculated ventilatory parameters.

Design: Retrospective observational study.

Objectives: To evaluate and identify the ventilatory, demographic, and clinical pre-extubation variables that are significant for estimating extubation readiness.
