Abbreviated multi-breath washout for calculation of lung clearance index.
Various functional residual capacity (FRC) repeatability criteria have been proposed for lung clearance index (LCI) measurement by multiple breath washout (MBW). Adult guidelines recommend three technically acceptable tests with FRC values within 10%, whilst preschool guidelines recommend two such tests. Feasibility of and need for recommendations in children is unclear. ⋯ Adult FRC repeatability recommendations improved LCI repeatability in pediatric subjects, but poor feasibility limited utility. In an experienced pediatric MBW center, recent preschool recommendations can be extended to two technically acceptable tests, irrespective of FRC repeatability, without significantly affecting mean LCI or compromising sensitivity.

A 4 year prospective study to determine risk factors for severe community acquired pneumonia in children in southern China.
Pneumonia is the major cause of death under 5 years. With high CAP numbers in China and growing access to PICUs, factors associated with severe CAP need to be determined to optimize care. ⋯ Young age and underlying congenital heart disease were associated factors for PICU support in CAP in China. Early referral if altered sensorium, high respiratory rate, head nodding, grunting and anemia, and universal access to conjugated vaccines may decrease morbidity and mortality.
