研究概览
简要总结
The objective of our project is to find procedures and/or parameters to predict the diagnostic recovery (≥ 60% of the administered fluid volume) of bronchoalveolar lavage (BAL) fluid before bronchoscopy and to assess the impact of using non-invasive mechanical ventilation (NMV) or continuous positive airway pressure (CPAP) to achieve diagnostic recovery in patients with chronic obstructive pulmonary disease (COPD) and interstinal lungs disease for whom BAL performed during ordinary bronchoscopy turns out to be non-diagnostic.
