Data are presented as n, n (%) or mean±sd, unless otherwise stated. BMI: body mass index; FEV1: forced expiratory volume in 1 s; % pred: % predicted; VC: vital capacity; PEF: peak expiratory flow; TLC: total lung capacity; RV: residual volume; PaO2: arterial oxygen tension; PaCO2: arterial carbon dioxide tension; HCO3−: bicarbonate; SaO2: arterial oxygen saturation.
