    Optical coherence tomography (OCT) in patients with acute respiratory failure on the ICU

    Introduction: Differentiating ARDS from other forms of respiratory failure can be difficult. By advancing an optic fiber through a diagnostic bronchoscope, followed by an automatic pullback mechanism, OCT enables real-time 3D imaging of the alveolar compartment and peripheral airways. Aim: To investigate feasibility of bronchoscopic OCT, and to describe different OCT patterns of the alveolar compartment in mechanically ventilated patients. Methods: Observational study of OCT imaging in mechanically ventilated patients for non-resolving acute respiratory failure with an indication for diagnostic bronchoscopy. Results: 9 patients were included with clinical features of acute respiratory failure and bilateral pulmonary infiltrates not fully explained ...
