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.

What are the effects of exercise on the expiratory reserve volume?

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.


How do you do capacity?

Calculate the IRV of a person with an active capacity of 4360ml an expiratory reserve volume of 1300ml and a tidal volume of 500ml?

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.


How does expiratory reserve volume change with exercise?

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?


What is FRV an abbreviation for?

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.


What is The volume of air that can be exhaled after a maximum inhalation?

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.


How might bronchitis affect the expiratoy reserve volume?

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.


What does ERV in respiratory system mean?

The ERV is the expiratory reserve volume, which is the amount of air that can be forcefully exhaled after a normal tidal volume exhalation.


What is the functional residual capacity FRC composed of?

Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
