A method for measuring total respiratory resistance (RT) using a forced oscillation technique was applied to children between 3 and 12 years of age. RT at midinspiration was higher than airway resistance (Raw) measured on the same children by total body plethysmography. Normal RT values were compared with results in children with asthma and cystic fibrosis. It is suggested that the technique could have a wider application in the assessment of airway obstruction in children.
