mMRC: modified Medical Research Council dyspnea scale; BMI: body mass index; FEV1: forced expiratory volume in one second; TLC: total lung capacity; RV: residual volume; 6MWD: six-minute walk distance; HRCT: high-resolution computed tomography; EBV: endobronchial valve; LVRS: lung volume reduction surgery; LVEF: left ventricular ejection fraction; PaCO2: carbon dioxide tension; PaO2: arterial oxygen tension.
* Endobronchial valves are implanted bronchoscopically in regions of the lung with little to no collateral ventilation to treat adult patients with hyperinflation due to severe emphysema.
¶ Chartis: A specialized catheter for bronchoscopic assessment of localized pressure and flow to assess collateral ventilation. Absence of collateral ventilation improves the likelihood of resorption atelectasis following endobronchial valve placement.
Δ StratX: Quantitative analysis of high resolution computed tomography images to assess amount of emphysematous destruction and fissure completeness. Greater fissure completeness predicts less collateral ventilation and a greater likelihood of success with endobronchial valve placement.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
