Association between oxygen saturation level during bronchoscopy and post-bronchoscopy adverse events: a retrospective cohort study.

ABSTRACT:

Background

Flexible bronchoscopy is widely used to diagnose and treat various respiratory diseases. However, caution is warranted for post-bronchoscopy adverse events. Although desaturation frequently occurs during bronchoscopy, its clinical impact and the optimal oxygen saturation level during the procedure remain unclear. This study aimed to investigate whether the percutaneous oxygen saturation (SpO₂) level during bronchoscopy is associated with the development of post-bronchoscopy respiratory adverse events.

Methods

In this single-center retrospective cohort study conducted from March 2020 to February 2021, 569 patients were classified into high or low oxygen saturation groups based on the SpO₂ level during bronchoscopy. The primary outcome was post
