1. Objective To discuss the clinical significance of impulse oscillometry (IOS) to determine the resistance of large and small airways and the compliance of lung.

2. Objective To discuss the diagnosis values of impulse oscillometry(IOS) to determine the chronic obstructive pulmonary diseases(COPD).

3. Methods Routine lung function and impulse oscillometry(IOS) were performed on 24 OSAHS patients(OSAHS group) and 12 normal subjects(control group).

4. Objectives:To investigate the clinical value of impulse oscillometry(IOS) in bronchial challenge test.

5. Objective To determine the manifestation of impulse oscillometry (IOS) in variation of respiration impedance on patients with extratracheal tumour.

6. Methods The impedance of respiratory system was measured by impulse oscillometry system (IOS) and compared with parameter values of routine pulmonary ventilation function in 117 patients with COPD.

7. This paper introduces the blood pressure algorithm based on the oscillometry , and then designs a electronic sphygmomanometer according to the algorithm.

8. Objective To study the respiratory function tests reference values of healthy children in China with impulse oscillometry(IOS).
