Background: Lung clearance index (LCI), measured using multiple breath inert gas washout (MBW) is a potentially useful test in infants with respiratory disease, particularly cystic fibrosis (CF). Clinical use is limited however by the need for specialist staff and equipment. We have previously described a novel method for infant MBW suitable for use outside of specialist laboratories.

This is a selection of papers presented at the 30th North American Cystic Fibrosis Conference held in Orlando in October 2016. The papers discussed are thought to be of particular interest to CF caregivers in the UK. We highlight the major themes covered in the conference including novel therapies, recently published and proposed guidelines and insights from registry studies.

Conventional MBW is based on simultaneous measurement of flow and gas concentrations. These two signals are aligned and combined to derive expired gas volumes from which lung volumes and measures of ventilation inhomogeneity are calculated.
