Expiratory reserve volume is decreased in a patient with emphysema. This patient will struggle to breathe out because air is getting trapped within the lungs. There is also an increase of co2 in the blood because of the inability for the patient to exhale.
Regular exercise can increase the strength and efficiency of respiratory muscles, including those involved in exhalation. This can lead to improved lung function, increased expiratory muscle strength, and potentially an increase in expiratory reserve volume over time.
It's the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume

What happens to residual volume, tidal volume, inspiratory reserve volume and expiratory reserve volume just after exercise while breathing deeply and rapidly? Do they increase, decrease or stay the same?
The Inspiratory reserve volume (IRV) is calculated by subtracting the tidal volume and expiratory reserve volume from the total lung capacity. In this case, the total lung capacity is the sum of the active capacity and the expiratory reserve volume, which equals 5660ml. Therefore, the IRV would be 5660ml - 500ml - 1300ml = 3860ml.
The amount of air beyond tidal volume is known as the inspiratory reserve volume (IRV) and expiratory reserve volume (ERV). Inspiratory reserve volume is the additional air that can be inhaled after a normal tidal inhalation, while expiratory reserve volume is the air that can be exhaled after a normal tidal exhalation. Together, these volumes contribute to the total lung capacity and are crucial for assessing respiratory function.
The abbreviation FRV stands for functional reserve volume. Functional reserve volume is used to describe the volume of air in ones lungs at the end of the expiratory position.
Vital Capacity (VC) is the maximum amount of air that can be exhaled after a maximum inhalation. But it differs from one person to another. For a normal sized male that would be 4600 ml.
Bronchitis affects your expiratory reserve volume because Bronchitis is an inflammation of the bronchi and the bronchioles which causes air passage to decrease so it's harder for a person to breath out so much air when they have an inflammation in their bronchi and bronchioles.
This is the amount of oxygen that is reserved in your body while you work out. The more that you work out the more of a reserve volume your body will have.
