Emphysema's effect on vital capacity increases as the disease progresses. Emphysema is a chronic obstructive pulmonary disorder (COPD) which obstructs the passage of air out of the lungs. As a person exhales with emphysema, the airways close prematurely which reduces the exhalation volume thus reducing vital capacity.

Increased vital capacity
What are four factors that can affect the vital capacity of a person?
Four factors that can affect the vital capacity of a person are age (vital capacity decreases with age), gender (males tend to have higher vital capacity than females), height (taller individuals usually have higher vital capacity), and physical fitness level (regular exercise can increase vital capacity).
How would pneumonia affect vital capacity?
no
Vital capacity in emphysema?
In emphysema, vital capacity is often reduced due to the destruction of alveoli and loss of elastic recoil in the lungs, which leads to air trapping and difficulty exhaling. This condition decreases the overall lung function, resulting in a lower ability to take in and expel air effectively. Patients may experience increased residual volume and decreased forced vital capacity, contributing to symptoms like shortness of breath. Overall, emphysema significantly impacts respiratory mechanics and gas exchange efficiency.
What can reduce vital capacity?
There are many reasons that could increase or decrease vital capacity in a person. Respiratory conditions are a major factor in how much air a person can take in.
What happenes to vc and TLC in severe emphysema?
In severe emphysema, vital capacity (VC) is typically reduced due to the destruction of alveoli, leading to decreased lung elasticity and air trapping. Total lung capacity (TLC) may be increased as a result of hyperinflation, where the lungs become overly distended, allowing for more air to remain in the lungs even after exhalation. This combination of reduced VC and increased TLC reflects the impaired respiratory mechanics characteristic of emphysema.

What is vital capacity of lungs?
the vital capacity of lungs is 3.5 liters to 4.5 litres
How does height affect vital capacity?
due to surface area. if you are taller your lungs will have a greater surface area which will raise the volume.
What lung values changed in the spirogram when the patient with emphysema was selected?
In a spirogram of a patient with emphysema, key lung values typically show a decreased forced expiratory volume in one second (FEV1) and a reduced FEV1/FVC (forced vital capacity) ratio, indicating obstructive lung disease. Additionally, total lung capacity (TLC) may be increased due to air trapping, while residual volume (RV) is also elevated. These changes reflect the impaired airflow and hyperinflation characteristic of emphysema.
What is vital lung capacity?
vital lung capacity is how much air remains in your lungs after you exhale
