What this Trial Is About

Researchers are studying how oxygen and breathing support are currently used in adult patients undergoing Fiberoptic Bronchoscopy (FOB). This is an observational study that aims to understand different oxygenation and ventilation methods used during FOB across various patient conditions, procedure types, and hospital settings. The study includes adults with respiratory issues such as acute respiratory failure, pneumonia, lung cancer, lung fibrosis, and interstitial lung disease. Participants will undergo the bronchial endoscopy procedure required for their condition. These procedures include toilet bronchoscopy to remove secretions or blood, broncho-aspirate, bronchoalveolar lavage, cytology brushing, biopsy, and endobronchial ultrasound. Researchers will record the type and size of the bronchoscope used and details about sedation and oxygen support methods, such as no support, standard oxygen therapy, high flow nasal cannula, non-invasive ventilation, or mechanical ventilation. During the study, investigators will monitor vital signs throughout the procedure and 15 minutes afterward. They will track any adverse events like oxygen drops, blood pressure changes, heart rhythm problems, or neurological issues. Clinical outcomes such as the need for increased respiratory support or hospital admission will also be recorded. The main outcome measured is the type of oxygenation strategy used during the approximately 30-minute bronchoscopy procedure.
