| expiratory dyspnea | Difficulty with the expiratory phase of breathing, often due to obstruction in the larynx or large bronchi, such as by a foreign body. (05 Mar 2000) |

| cardiac dyspnea | Shortness of breath of cardiac origin. (05 Mar 2000) |
|---|---|
| paroxysmal nocturnal dyspnea | Acute dyspnea appearing suddenly at night, usually waking the patient after an hour or two of sleep; caused by pulmonary congestion with or without oedema that results from left-sided heart failure following immobilization of fluid from dependent areas after lying down. (05 Mar 2000) |
| nocturnal dyspnea | Dyspnea occurring at night, several hours after assuming recumbent position. Occurs in heart failure and results from reabsorption of water from dependent areas after removal of effect of gravity, causing hypervolaemia, aggravating left-ventricular failure. (05 Mar 2000) |
| dyspnea | <symptom> Shortness of breath, difficult or laboured breathing. Origin: Gr. Dyspnoia = difficulty of breathing (18 Nov 1997) |
| dyspnea, paroxysmal | A form of respiratory distress related to posture (especially reclining at night) and usually attributed to congestive heart failure with pulmonary oedema. It appears suddenly at night, usually wakening the patient after an hour or two of sleep. It is also called paroxysmal nocturnal dyspnea. (12 Dec 1998) |
| Traube's dyspnea | An obsolete eponym for inspiratory dyspnea with maximal expansion of the chest and a slow respiratory rhythm. (05 Mar 2000) |
| exertional dyspnea | Excessive shortness of breath after exercise. (05 Mar 2000) |
| functional dyspnea | Shortness of breath without apparent underlying disease. (05 Mar 2000) |
| maximal expiratory flow rate | <chest medicine, physiology> Measurement of rate of airflow during the first liter expired after the first 200 ml have been exhausted during a forced vital capacity determination. Common abbreviations are MEFR, FEF 202-1200, and fef 0.2-1.2. Acronym: MEFR (21 Jun 2000) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| peak expiratory flow | The maximum flow at the outset of forced expiration, which is reduced in proportion to the severity of airway obstruction, as in asthma. (05 Mar 2000) |
| peak expiratory flow rate | Measurement of the maximum rate of airflow attained during a forced vital capacity determination. Common abbreviations are pefr and pfr. (12 Dec 1998) |
| positive end-expiratory pressure | A technique used in respiratory therapy in which airway pressure greater than atmospheric pressure is achieved at the end of exhalation by introduction of a mechanical impedance to exhalation. (05 Mar 2000) |
| negative end-expiratory pressure | A subatmospheric pressure at the airway at the end of expiration. (05 Mar 2000) |
| expiratory | <physiology> Pertaining to, or employed in, the expiration or emission of air from the lungs; as, the expiratory muscles. Source: Websters Dictionary (01 Mar 1998) |
