BACKGROUND:
The only lung volume that can be measured reliably in infants is the functional
residual capacity (FRC). Published reference values vary, thus, there is a need to determine values for
healthy infants using the available equipment.
OBJECTIVES:
To determine the normal values of FRC in healthy infants using the baby body
plethysmogram (CareFusion) and to determine the correlation between FRC and weight, length, age, and
gender.
METHODS:
FRC was measured using the CareFusion MasterScreen baby body plethysmogram in 62
healthy infants aged 1-24 months old. FRC was measured after sedation with Chloral hydrate at 50 mg/kg
body weight. Three measurements were performed from which the mean (SD) FRC was calculated. To
depict the change in FRC with growth, regression analysis between FRC as dependent variable and
weight, length, and age as independent variables was done.
CONCLUSION
The FRC values obtained in this study is 24.56 ml/kg (4.41). There is a direct
correlation of FRC with age, weight, and length. The result of this study was comparable to other studies and may be used as a reference value for healthy infants.
