“…Multiple studies have shown that improvement after bronchodilator testing in R5Hz by IOS correlates well with a significant response by spirometry or plethysmography [42,47,48]. Initial pre-and postbronchodilator studies suggested that an increase in R5Hz by 40% was needed to distinguish asthmatic from nonasthmatic children [44].…”

Pulmonary function testing (PFT) is of great importance in the evaluation and treatment of respiratory diseases. Spirometry is simple, noninvasive, and has been the most commonly used technique in cooperative children, obtaining reliable data in only a few minutes. The development of commercially available equipment as well as the simplification of previous techniques that now require minimal patient cooperation applied during tidal breathing have significantly stimulated the use of PFT in younger children. Tidal breathing techniques such as impulse oscillometry, gas dilution, and plethysmography have permitted previously unobtainable PFT in children 2 to 5 years of age. The purpose of this review is to help clinicians become familiar with available PFT techniques used in young children by discussing their general principles, clinical applications, and limitations.

“…Initial pre-and postbronchodilator studies suggested that an increase in R5Hz by 40% was needed to distinguish asthmatic from nonasthmatic children [44]. Most recent studies suggest that a change in R5Hz by 30% to 35% is enough to be considered a positive test [42,47,48].…”

“…5,6 Furthermore, owing to the relative simplicity of the technique, within pediatric populations, IOS has been shown to be a useful alternative to spirometry. 7 The usefulness of IOS in children has been well demonstrated and has even shown evidence of AHR in the absence of significant changes in spirometry. 8 This has allowed IOS parameters to be investigated as potential surrogate markers of AHR instead of spirometry in children.…”

“…It was developed as a patient-friendly lung function test that minimizes demands on the patient and requires only passive cooperation of the patient breathing normally through the mouth. 7 Because forced oscillometry is performed without closure of a valve connected to the mouthpiece and without maximal or forced respiratory maneuvers, it is unlikely that forced oscillometry itself will alter smooth muscle tone in the airway. 8 The forced oscillometry apparatus generates small pressure oscillations that are applied at the mouth and transmitted into the lungs to help determine the impedance (Z) of the respiratory system.…”
