Ventilator settings for fibreoptic bronchoscopy during mechanical ventilation: a study protocol for a pragmatic randomised double-blind controlled trial VentSetFib.

ABSTRACT:

Introduction

Fibreoptic bronchoscopy (FOB) is a challenging procedure during mechanical ventilation (MV) as it considerably reduces the endotracheal tube's internal diameter, causing a drastic increase in respiratory resistance, which may compromise the delivery of ventilatory assistance. According to respiratory physiology principles applied to MV, the reduction of inspiratory flow and tidal volume is likely to reduce airway pressure during the inspiratory phase when respiratory resistances increase. Based on this assumption, we propose new ventilator settings aimed at reducing airway pressure during FOB. This study represents the first investigation to test special ventilator settings in order to facilitate FOB during MV.
