Abstract:
Diagnostic or therapeutic flexible bronchoscopy is often necessary in severely ill patients. These patients often have comorbidities that increase the risk of bronchoscopy-related complications. Noninvasive ventilation might decrease the risk of these complications in patients with severe refractory hypoxemia, postoperative respiratory distress, or severe emphysema, and in pediatric patients. Noninvasive ventilation may prevent hypoventilation in patients with obstructive sleep apnea and obesity hypoventilation syndrome who require bronchoscopy, and may assist in the bronchoscopic evaluation of patients with expiratory central-airway collapse. We describe the indications, contraindications, and technique of flexible bronchoscopy during noninvasive ventilation.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
