Abstract
Introduction: Freeflowmetry is the new method of air flow and air volume measurement during forced and free breathing through the open or partially closed mouth or through the nose. Application of tight silicone mask connected with dPP® pneumotachograph allows adaptation of the natural resistance of the oral cavity in order to reduce the airway collapse.
The aim of the study was to compare the results of examination performed with dPP® pneumotachograph with mouthpiece, with the results of examination performed with silicone mask
Method: The examinations were performed using PNEUMO® PC spirometer [abcMED, PL] in group of COPD patients: 6 female and 4 male at age of 75±5 years and in control group of healthy: 6 female and 2 male at age 73±6 years.
The results are shown in table 1.
Table 1
Conclusion: Freeflowmetric examination can contribute to the optimization and individual adaptation of treatment, the determining of the phenotype of bronchial obstruction and/or airway collapse in common diseases such as COPD and asthma. Further studies are required for the comparison of freewlowmetric test results before and after physical exercise and before and after application of bronchodilator.
