Non-invasive Ventilation Assisted Fiber-optic Bronchoscopy

Официальное название

Efficacy and Safety of Using Non-invasive Ventilation Assisted Fiber-optic Bronchoscopy

Обзор

The purpose of this study is the evaluation of using bi-level positive airway pressure ventilation in candidates for fiber-optic bronchoscopy regarding benefits and drawbacks.

Подробное описание

In this study patients who will be candidate for fiber-optic bronchoscopy for diagnostic or therapeutic reasons will be evaluated by the Chest Medicine Department, Mansoura University Hospitals. All patients will be subjected to full history taking, full examination, routine laboratory investigations, arterial blood gases (ABG), chest X-ray, chest computed tomography (CT). Non-invasive ventilation: Group 1 (hypoexemic patient who will undergo bronchoscopy under non- invasive ventilation{NIV}) will be on NIV half an hour prior and throughout the bronchoscopic sampling and after the procedure until reach the baseline criteria, Group 2 (hypoxemic patients who will undergo conventional bronchoscopy ) will be on conventional oxygen therapy half an hour prior and throughout the bronchoscopic sampling and after the procedure until reach the baseline criteria, Group 3 (non- hypoxemic patients who will undergo conventional bronchoscopy ) will be on NIV throughout the bronchoscopic sampling and after the procedure until reach the baseline criteria, Group 4 (non- hypoxemic patients who will undergo conventional bronchoscopy) will be on conventional oxygen therapy throughout the bronchoscopic sampling and after the procedure until reach the baseline criteria.
