Dyspnea was a medical term describing a sensation of difficulty in breathing.
Dyspnea was a symptom (e.g. the patient noticed it him/herself) and not a sign (e.g. only a doctor noticed the sign during a medical examination), except in certain cases or with certain species, Tellarites for example.
Doctor Bashir downloaded data about dyspnea, coughing and other pulmonary disorders onto a PADD shortly before he left to attend a medical conference on Casperia Prime in 2374. (DS9: "Inquisition")
