Changes of impulse oscillometry (IO) parameters were well studied in patients with obstructive disorders. Investigations of lung mechanics using IO meet less often in patients with combined restrictive and obstructive disorders. Current tests of lung function demand performance of forced and maximal breathing maneuvers and they are difficultly feasible for patients with severe dyspnoea. IO has been developed as a measure of lung function that requires only passive cooperation and may be used with success in patients with severe pulmonary disorders.
To evaluate the possibility of the impulse oscillometry to detect the pulmonary disorders in patients with mixed lung function abnormalities.
57 healthy volunteers
(30 M/27F, mean age 47 ± 1 years)
17 patients with extrinsic allergic alveolitis
(8M/9F, mean age 45±3 years).
FD Rrs = R5 – R20
X5 = |X5 – X5pred.|
The changes of IO parameters were not specific to detect the changes of elastic properties in patients with mixed lung disorders.
IO may be more useful to detect airway disorders in such patients.
