Applied practice of multiple breath nitrogen washout in adults and children

This is a blended course with online learning available prior to the practical day. We suggest 1 to 2 days to complete the online learning. The material will be made available 4 weeks prior to the date of the course. Following the course, there will be a quiz and MBN2W analysis exercise available.

Lung clearance index (LCI) has been demonstrated to be more sensitive than spirometry in detecting early lung disease, particularly in cystic fibrosis. Multiple breath washout measurement is feasible in young children allowing longitudinal tracking. With CFTR modulators improving lung function outcomes, the routine clinical use of more sensitive outcomes such as LCI will increase in children and adults.

This course will provide training in the practical performance of MBN2W in children and adults and is run by the London MBW Training Centre (Faculty from Department of CF and Chronic Lung Infection at Imperial College London, Royal Brompton Hospital, Harefield Hospital, and the Lung Function Unit at Great Ormond Street Hospital).
