A computerized tool for the systematic visual quality assessment of infant multiple-breath washout measurements.

ABSTRACT:

Background

Multiple-breath washout (MBW) is a sensitive method for assessing lung volumes and ventilation inhomogeneity in infants, but remains prone to artefacts (e.g., sighs). There is a lack of tools for systematic retrospective analysis of existing datasets, and unlike N₂-MBW in older children, there are few specific quality control (QC) criteria for artefacts in infant SF₆-MBW.

Aim

We aimed to develop a computer-based tool for systematic evaluation of visual QC criteria of SF₆-MBW measurements and to investigate interrater agreement and effects on MBW outcomes among three independent examiners.

Methods

We developed a software package for visualization of raw Spiroware (Eco Medics AG, Switzerland) and signal processed WBreath (ndd
