[Comparative analysis of basic spirometric parameters recognized by different authors as normal values for the same individuals].

Basic spirometric parameters (VC, FEV1, MVV) were recorded in 60 people (30 males and 30 females) without ventilatory disturbances. These results were compared with the normal values of Berglund, Kory, Cournand, Morris and Nikodemowicz. A statistical analysis was carried out using the differential test. The results differed significantly between each other. The most stable parameter that did not differ was FEV1. This may be an argument for calculating IMBC rather than recording maximal ventilatory response.
