Due to the fact that the treatment in Chronic Respiratory patients is
almost completely palliative, it is important to find some kind of sca
le which can yield precise information on the limitations which the su
bject has to face on his/her day-to-day life. Respiratory function tes
ts and Dyspnea Scales are not appropriately enough systems for such pu
rpose, therefore during the last few years several CV tests have been
applied, general or specific, standardized or not. The method which cu
rrently seems more useful is CRQ, even tough SGRQ seems to be the more
promising, due to the fact that it has been fully standardized and al
lows interindividual as well as and in interpopulation comparations.
