Activity limitation: a major consequence of dyspnoea in COPD.

I n the present issue of the European Respiratory Review, JOLLEY and MOXHAM [1] present ‘‘A physiological model of patient-reported breathlessness during daily activities in COPD [chronic obstructive pulmonary disease]’’. The purpose of their interesting approach is to explain why a given patient may experience breathlessness in some particular situations of his/her daily life, based on the various possible mechanisms of dyspnoea in COPD. This understanding may obviously help in building individualised relieving strategies through counselling and education, occupational therapy, pharmacological agents and physical training.
