]. The fact that in our case we do not have variations in hystere-
sivity with bronchial challenge is explained by the fact that in all asthma patients,
a spontaneous improvement higher than 12 % was absent, due to prior medication
intake (see Table

). Nevertheless, the tissue damping and tissue elastance coef-
ficients were sensitive to detect variations between the groups when evaluated inde-
