Incidence and Risk Factors of Hypoxemia During Interventional Rigid Bronchoscopy Under Spontaneous-assisted Ventilation

Abstract

Incidence of intraoperative hypoxemia during interventional rigid bronchoscopy for tracheobronchial stenosis under spontaneous-assisted ventilation was 25.5%. Risk factors for hypoxemia were a degree of tracheal stenosis ≥75% and tumor removal procedure.
