We hypothesized that a new test of infant lung function, less affected by shifts in lung volume, might better detect bronchodilator effects. Using the raised volume forced expiration technique (RVFET), the effect of a bronchodilator on lung function was studied in 22 infants with a history of recurrent wheeze and five healthy infants. Forced expiratory volume in 0.75 s (FEV0.75), forced expiratory vital capacity (FVC), and forced expiratory flow at 75% of FVC (FEF75%) were measured by forcing expiration, using an inflatable jacket from a lung volume set by an inspiratory pressure of 20 cm H2O. A minimum of five measurements were made at baseline and following the administration of 500 μg of salbutamol from a metered dose inhaler via a small volume metal spacer. Changes in lung function in the group of 25 infants who received salbutamol were compared to seven infants who received placebo aerosol.
