AB  - Background: Spirometry is frequently used to evaluate lung function in children older 7 years with obstructive or restrictive lung diseases such as asthma or cystic fibrosis. The development of methods of the assessment of respiratory function in younger children is necessary.Aim: To introduce the method CBPhG for assessment of respiratory function.Materials and methods: 200 healthy patients (age 1-18 years) without lung diseases. Lung function was examined by CBPhG. Registration of respiratory sounds is recorded by high sensitivity transducer in wide range of frequencies during quiet breathing: low 0,2-1,2, middle 1,2-5,0 and high frequency >5,0 kHz. The registration is performed for 10 seconds. The CBPhG has a high overall reliability (88.7%), sensitivity (proportion of true positive cases) (86.4%), specificity (proportion of true negative cases) (90.9%).Results: Data were 0,12±0,96mcJ in high frequency range, 3,04±0,13mcJ in middle, 71,7±29,8mcJ in low in children without lung diseases, regardless of age.Conclusions: CBPhG is a high sensitive method which may be used for assessment of respiratory function in even ages, especially in the childhood. This method allows to monitor efficiency of therapy of bronchial asthma.
