Measure Lung Capacity
- Stretch your balloon.
- Take a deep breath and blow all at once into the balloon and close it off.
- Shape the balloon into a sphere shape while holding the air in.
- Ask a partner to measure the circumference of the balloon at the middle. (You could measure the diameter and for younger kids this might be best, but it’s less accurate)
- Record the number in centimeters.
- Repeat two more times.
- If your hypothesis indicates exercise, repeat after doing a set of exercises.

How do you calculate lung volume?
2.1. The total lung capacity (TLC) is the volume of gas in the lung at the end of a full inspiration. It is either calculated from: TLC = RV+IVC, or from: TLC = FRC+IC; the latter is the preferred method in body plethysmography. It can also be measured directly by the radiologic technique.
Does peak flow measure lung capacity?
A peak flow meter is a portable, inexpensive, hand-held device that measures your ability to push air out of your lungs. Air flow is measured by the amount of air that you can blow out in one "fast blast." Peak flow meters come in two ranges to measure the air pushed out of your lungs.
How does a spirometer measure lung capacity?
In a spirometry test, while you are sitting, you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time. When standing, some numbers might be slightly different.
