Article information

Se ha estudiado el efecto de broncodilatadores β-estimulantes con los parámetros más habituales de espirometría y pletismografía corporal.

Para valores de Raw por encima de unas 7 unidades, este parámetro es adecuadamente discriminativo de los valores pre y posbroncodilatador y además guarda una alta correlación con el trabajo viscoso de vías aéreas. Por estas razones se considera el parámetro de elección en la valoración de broncodilatadores.

Para valores más bajos es preferible emplear la SRaw o el V.E.M.S.


The efects of β-stimulating bronchodilators have been studied be means of the most common parameters of spirometry and corporal plethysmography.

For Raw values 7 units this parameter is sufficiently discrirninating of pre- and post-bronchodilator values and also manteins a high correlation with the viscous function of the air passages. For these reasons it is considered the prefered parameter in the evaluation for bronchodilators.

For lower values the use of SRaw or V.E.M.S. is prefered.
