[The influence of helium concentration in determining respiratory function parameters].
Before a research about normals values of lung diffusing capacity for CO in Italian people, the Authors investigate if different concentration of Helium in respiratory gases could have any influence on data. Experiments were performed by testing 8 male subjects. Each one repeated lung function tests three times using gas mixtures with different Helium percentage. Results were evaluated by meaning of t Studnt's and Bartlett's Chi-square tests. Results show no significant difference.
