20 Ιουν 2024 · An expiratory reserve volume (ERV) is the amount of air that you can exhale when you push out all the air possible after your "normal" breath. This extra ERV air is a part of your total lung vital capacity. It is one of the metrics measured during lung volume testing through spirometry, a type of pulmonary function test.

2 Δεκ 2022 · It is above your normal breath and is usually exhale when you breathe out forcefully. The normal value for ERV is almost 1100 ml in males and 800 ml in females. The ERV formula can be used to calculate expiratory reserve volume. The formula for ERV is “VC = TV+IRV+ERV” or “ERV= VC-TV-IRV“.
