WebbIn chronic obstructive pulmonary disease (COPD), spirometry is used to demonstrate persistent airflow limitation and define disease severity, in conjunction with respiratory symptoms like dyspnoea, cough or sputum production [ 2 ]. Despite this, spirometry has several shortcomings. WebbWe compared parameters of maximal expiratory flow with other tests used in the detection of small airways obstruction (SAD) in a canine model of bronchiolitis obliterans.
