Implication

Supports multifactorial dyspnea assessment in research; leaves open causal roles or therapeutic targeting in patients.

Structured PICO

Population

20 subjects (2 normal subjects and 18 patients with a heterogeneous group of pulmonary diseases, obesity, muscular weakness, and cardiac disease) with exercise capacity ranging from 250 to 1,900 kpm/min.

Intervention

Incremental exercise test (50 to 100 kpm/min) to maximal capacity

Outcome

Intensity of breathlessness measured using a category scale and its relationship to respiratory muscle effort variables (MIP, Ppl, VT/VC, VI, fb, TI/Ttot)patient reported

The intensity of breathlessness during exercise is multifactorial and relates significantly to respiratory muscle effort, velocity of contraction, and muscle shortening.
