Multivariate Support for Three Distinct Approaches to the Assessment of Respiratory Sensation in Patients with Obstructive Lung Disease
Dyspnea is a common complaint of patients with obstructive airway disease (OAD). It is the major reason that both occupational and recreational activities are limited in such patients. Accordingly, issues surrounding measurement of shortness of breath in patients with obstructive lung disease have received increasing attention (e.g., Altose, 1985; Killian, 1985). Reliable assessment of symptoms is important for many reasons including the evaluation of symptom severity, the management of breathlessness, and the elucidation of physiologic mechanisms subserving respiratory sensation.
