[Forced oscillation technique in respiratory system studies. III. Compliance and airway resistance in children with lung fibrosis].

In patient with lung fibrosis we need to monitor lung compliance to evaluate the progress of the illness or efficacy of the treatment. This examination is not well tolerated and difficult to perform, especially in children. We compared classic measurements of static compliance of the lung and airway resistance with parameters derived from forced oscillations measurements--compliance and resistance of respiratory system. Correlation coefficients were respectively 0.85 for compliance and 0.70 for resistance. We conclude that it is possible to supplement classic measurements, especially in evaluating the dynamics of illness.
