Patients were prospectively followed with sleep studies, spirometry and peak inspiratory muscle pressure. Ten patients were studied before and after 3 nights withdrawal from NIV.NIV normalised nocturnal gas exchange in all patients and diurnal gas exchange in patients with ventilatory insufficiency. The effects persisted over 25.3±12.7 months. Nocturnal transcutaneous partial pressure of carbon dioxide improved from (baseline versus latest control) 7.1±1.3 to 5.5±0.6 kPa (53.7±9.9 to 41.6±4.8 mmHg), diurnalcarbon dioxide arterial tension from 6.3±1.6 to 5.4±0.5 kPa (47.5±11.9 to 40.6±3.6 mmHg).NIV improved respiratory disturbance index, arousals from sleep, nocturnal heart rate and sleep architecture. Vital capacity decreased in five adolescents with Duchenne muscular dystrophy −183±111 mL·yr−1 but remained stable in 25 children with other conditions (8±78 mL·yr−1). Three nights withdrawal of NIV in 10 previously stable patients resulted in prompt deterioration of SDB and gas exchange back to baseline but could be instantly normalised by resumption of NIV.Noninvasive (positive­pressure) ventilation has favourable long­term impact on nocturnal and diurnal gas exchange and sleep and in patients with non­Duchenne neuromuscular disorders on vital capacity as well. It is indicated in children and adolescents with symptomatic sleep­disordered breathing or ventilatory insufficiency due to neuromuscular disorders.Supported by grants from the University ofEssen, grant #107505‐0/IFORES, by a research grant founded by VitalAire Deutschland GmbH and Heinen & Löwenstein GmbH, and by the Alfried Krupp von Bohlen and Halbach Foundation. ¶Both authors contributed equally to this article.
