To test lung capacity, doctors/nurses can use spirometry. Spirometry involves the patient exhaling into a mouthpiece/tube that is connected to a computerized device. This divice monitors the amount of air the patient is exhaling. Once the person fully exhales, the results can be analyzed by either viewing the results on a computer monitor or by printing the results out.

What does total lung capacity equals?
Total lung volume equals Vital Capacity + Residual Volume.
How many cubic units needed to fill the space inside a figure?

How is lung capacity measured and what factors can affect it?
Lung capacity is measured using a device called a spirometer, which calculates the volume of air a person can inhale and exhale. Factors that can affect lung capacity include age, gender, height, physical fitness, smoking habits, and certain medical conditions like asthma or COPD.
What is the equation to measure lung volume?
The equation to measure lung volume is Total Lung Capacity (TLC) = Vital Capacity (VC) + Residual Volume (RV). TLC represents the maximum amount of air the lungs can hold, VC is the maximum amount of air that can be exhaled after a deep inhalation, and RV is the amount of air that remains in the lungs after maximum exhalation.
What is lung capacity meant by?
Your total lung capacity is the total volume of the lung after maximum inspiration. (average 6 litres).
What does lung capacity have to do with healthy lungs?
Lung capacity is measured by a spirometer giving you this measurement.Total Lung Capacity = vital capacity + reserve volume = approximately 6 L.Any less than the normal volume will cause a loss of gas exchange. It may not seem much at first but if it progresses, it can lead to the what might be called suffocation. You can not get enough oxygen in the lungs for cell metabolism and it will finally lead to death.
What units are maximum lung volume measured in?
inches
Can you use the spirometer to measure your total lung capacity?
No. A spirometer can be used to measure the volume of breath a person can expire but it is impossible to expire your entire lung capacity. This is due to the "dead space" capacity that remains to stop the collapse of the alveoli. As the alveoli are spherical and lined with mucus if they collapse it would be impossble for them to be filled again and so some air must remain within them. It is, however, possible to estimate someone's total lung capacity from the spirometer reading.
The lung volume that represents the total volume of exchangeable air is the?
The lung volume that represents the total volume of exchangeable air is the vital capacity. It is the maximum amount of air a person can exhale after taking the deepest possible inhalation.
What is the lung volume that represents the total volume of exchangeable air?
vital capacity
Can a man's lungs hold more are than a women's lungs?
Lung capacity is a physical difference in the volume of the lungs. Lung capacity depends on how much air can fill the lungs. A man's lung capacity is larger than a woman's lung capacity.
What measurement in addition to vital capacity is needed before you can calculate your total lung capacity?
Residual volume
