  1. Categorical variables are presented as counts and percentages. Normally distributed continuous variables are presented as mean ± SD. Paired t-tests were used to compare pre-and postprocedural means. DLCO; diffusing capacity for carbon monoxide; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; RV, residual volume; SpO2; oxygen saturation; TLC, total lung capacity
