结局指标
主要结局
Expiratory Time Constants vs Fissure Completeness
时间窗: 1 year
We will examine the correlation between lobar expiratory time constants and fissure completeness by StratX
Ratio of residual volume over functional residual capacity by 4DXV
时间窗: 6 months
We will compare an XV hyperinflation index to traditional pulmonary function tests (PFTs) and outcomes
次要结局
- Improvement in Saint George Respiratory Questionnaire (SGRQ)(1 year)
