What is a significant concern during bronchoscopy for a mechanically ventilated patient?

During bronchoscopy for a mechanically ventilated patient, one of the most significant concerns is airway obstruction. This procedure involves inserting a bronchoscope into the airways, which can potentially lead to the blockage or swelling of the airways due to secretions, foreign bodies, or trauma caused by the bronchoscope itself. For a patient who is already dependent on mechanical ventilation, maintaining an open and patent airway is crucial for effective ventilation and oxygenation. If the airway becomes obstructed, it can quickly lead to severe respiratory compromise, making this a primary concern during the procedure.

While low oxygen levels, cardiac arrest, and hypoventilation are also potential issues during bronchoscopy, the immediate risk of airway obstruction directly impacts the ability to maintain ventilation in these patients. Therefore, the focus on ensuring a clear airway is vital for patient safety during such interventions.
