Data are presented as mean±sd unless otherwise stated. P_aO2: arterial oxygen tension; P_aCO2: arterial carbon dioxide tension; %sleepS_pO2<90: time spent with oxygen saturation measured by pulse oximetry (S_pO2) <90%; S_pO2mean: mean S_pO2; S_pO2min: minimum S_pO2; V_T: tidal volume; RR: respiratory rate.
