Perception of asthma

Lancet. 1976 Apr 24;1(7965):882-4. doi: 10.1016/s0140-6736(76)92097-3.


Subjective assessment and objective measurements of airways obstruction were compared in 82 patients during methacholine-induced asthma. 15% of the patients were unable to sense the presence of marked airways obstruction (forced expired volume in 1 s less than 50% of the predicted normal value). These subjects could not be characterised as a distinct group on the basis of their sex, age, or duration of their asthma. This reinforces the need for objective measurement of lung function in the management of asthma.
