Complex Breathlessness

Complex breathlessness (breathlessness with an unclear cause or that  appears disproportionate to underlying causes) is an important and often  neglected condition that presents a challenge to both patients and  clinicians. This Monograph aims to provide clinicians at all levels with  a comprehensive guide to complex breathlessness. Covering all aspects  of this challenging clinical scenario, it will prove a useful resource  when faced with a symptomatic breathless patient with no obvious  underlying cause or with disproportionate symptoms. Several less  commonly considered clinical entities and their associated features are  highlighted, and approaches to breathlessness management are suggested  in the absence of a clear diagnosis or set of abnormalities on  investigation.
