Abstract

OBJECTIVE: To describe the pattern and magnitude of lung volume change during open endotracheal tube (ETT) suction in infants receiving high-frequency oscillatory ventilation (HFOV). DESIGN: Prospective observational clinical study. SETTING: Tertiary neonatal intensive care unit. PATIENTS AND PARTICIPANTS: Seven intubated and muscle-relaxed newborn infants receiving HFOV. INTERVENTIONS: Open ETT suction was performed for 6 s at -100 mmHg using a 6-F catheter passed to the ETT tip after disconnection from HFOV. The HFOV was then recommenced at the same settings as prior to ETT suction. MEASUREMENTS AND RESULTS: Change in lung volume (DeltaV (L)) referenced to baseline lung volume before sucti..
