    What is respiratory volume & expiratory reserve volume?
    Respiratory volumes are the amount of air inhaled, exhaled, and stored in your lungs. Along with expiratory reserve volume, some terms that are often part of a ventilatory pulmonary function test and can be helpful to know include: Tidal volume. The amount of air you typically breathe into your lungs when at rest and not exerting yourself.

    What is inspiratory reserve volume?
    Inspiratory reserve volume. The amount of extra air inhaled — above tidal volume — during a forceful breath in. When you exercise, you have a reserve volume to tap into as your tidal volume increases. The average inspiratory reserve volume is about 3000 mL in males and 2100 mL in females. Vital capacity.

    What is expiratory reserve volume (ERV)?
    Your expiratory reserve volume is the amount of extra air — above-normal volume — exhaled during a forceful breath out. Measured with spirometry, your ERV is part of the data gathered in pulmonary function tests used to diagnose restrictive pulmonary diseases and obstructive lung diseases.

    What is the difference between tidal volume and expiratory reserve volume?
    The amount of air you breathe in is your tidal volume. After you breathe out, try to exhale more until you are unable to breathe out any more air. The amount of air you can force out after a normal breath (think about blowing up a balloon) is your expiratory reserve volume.

    What is forced expiratory volume in 6 seconds (fev6)?
    Similarly, forced expiratory volume in 6 seconds (FEV6) is the volume of forcibly exhaled air measured during 6 seconds. Spirometry is a test used to measure the ability of a person to inhale and exhale air respective to time. Forced expiratory volume (FEV) is one of the main results of spirometry.
