Abstract
Use of long-term ventilation (LTV) benefits patients with a diverse range of conditions, including Duchenne muscular dystrophy, motor neurone disease and scoliosis [1]. Patients with pulmonary disease as well as neuromuscular disease can benefit from LTV. COPD patients treated with LTV experience a reduction in hospital admissions and the use of LTV in cystic fibrosis (CF) patients is increasing [2, 3].
Guidelines suggest that exhaled gases do not reach the outlet of noninvasive ventilators in clinical use. In this study, when tidal volumes exceeded 800 mL, exhaled gases did reach the ventilator, leading to a risk of cross-infection between users.https://bit.ly/3EdvtY6
