| ERV | Expiratory Reserve Volume |
| expiratory centre | The region of the medulla oblongata that is electrically active during expiration and where electrical stimulation produces sustained expiration. (05 Mar 2000) |
|---|---|
| expiratory reserve volume | The extra volume of air that can be expired with maximum effort beyond the level reached at the end of a normal, quiet expiration. Common abbreviation is erv. (12 Dec 1998) |
| expiratory resistance | Resistance to flow of gas out of the lungs or the total resistance to flow of gas during the expiratory phase of the respiratory cycle. (05 Mar 2000) |
| expiratory stridor | A singing sound due to the semi-approximated vocal folds offering resistance to the escape of air. (05 Mar 2000) |
| zero end-expiratory pressure | Airway pressure which, at the end of expiration, equals atmospheric pressure. (05 Mar 2000) |
| forced expiratory flow | Expiratory flow during measurement of forced vital capacity; subscripts specify the exact parameter measured, e.g., peak instantaneous flow, the instantaneous flow at some specified point on the curve of volume expired versus time, or on the flow-volume curve, the mean flow between two expired volumes. (05 Mar 2000) |
| forced expiratory flow rates | Measurements of rates of airflow during a forced vital capacity determination. (12 Dec 1998) |
| forced expiratory time | The time taken to expire a given volume or a given fraction of vital capacity during measurement of forced vital capacity; subscripts specify the exact parameters measured. (05 Mar 2000) |
| forced expiratory volume | Measure of the maximum amount of air during a forced vital capacity determination that can be expelled in a given number of seconds. It is usually given as fev followed by a subscript indicating the number of seconds over which the measurement is made, although it is sometimes given as a percentage of forced vital capacity.
