Definition of expiratory reserve volume Ask a medical professional for a definition of expiratory reserve volume (ERV) and they’ll offer something along the lines of: “The extra volume of air that can be expired from the lungs with determined effort following a normal tidal volume expiration.” Let’s make that easier to understand. Picture yourself sitting normally and breathing as you do when you are not exerting yourself orexercising. 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. You can tap into this reserve volume when you exercise and your tidal volume increases. To sum up: Your expiratory reserve volume is the amount of extra air — above anormal breath — exhaled during a forceful breath out. The average ERV volume is about 1100 mL in males and 800 mL in females. 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:
The amount of lung capacity varies from person to person based on their physical makeup and their environment. You are likely to have a larger volume if you:
You are likely to have a smaller volume if you:
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 term for the quantity of air in the lungs?Tidal volume is essentially every breath a person takes. It is one of the main determinants of minute ventilation and alveolar ventilation. Minute ventilation, also known as total ventilation, is a measurement of the amount of air that enters the lungs per minute. It is the product of respiratory rate and tidal volume.
What is the term for the amount of air moved into and out of your lungs with normal resting breathing?The correct answer is (a) tidal volume. Tidal volume is the type of respiratory volume that defines the amount of air (gas) that moves in and out of the lungs during each respiratory cycle (normal breathing).
What is the term used to describe the volume of air that remains in the lungs following exhalation of the tidal volume?The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.
What is the term used to describe the amount of air that can be inhaled and exhaled with the deepest possible breath?The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle.
