In infants and very young children, functional residual capacity (FRC) is the lung volume most frequently measured and gas dilution techniques are most frequently used to measure FRC. We compared measurements of FRC by helium dilution (FRCHe) and nitrogen washout (FRCN2) in a lung model of known volumes (20, 40, 60, 80 mL) in 8 normal infants (NL), 8 infants with acute respiratory illness (ARI), and 7 infants with chronic lung disease (CLD). In the model lung, measurements of FRCHe had a… CONTINUE READING
