The correct way the measure vital capacity is by using a spirometer.
It can also be estimated this way:
Vital Capacity can be measured with a string, calculator, ruler and balloon, believe it or not. Blow up the balloon and let it out a few times to stretch the rubber. Then take a very deep breath and blow out all the air that you can into the balloon. Tie it off. Pass the piece of string around the widest part of it to measure it. Using the ruler, measure the string. (My VC is very good, it's 4.2, and so my string was about 60cm long.) Divide the meaurement of the string by pi (if you don't have suitable calculator, you can divide by 3.14 on a standard calculator) and compare the number to this chart: Balloon diameter (centimetres:)
is your final number that you got by dividing by pi. Balloon diameter: Approximate vital capacity in litres:

Theoretical vital capacity:
Look for Vital capacity in Wikipedia for the formula. There are also online calculators.
i dont' knw
My vital capacity is 1650cc (Yes, it's very low, but I'm twelve and I'm small). cc is used to measure vital capacity.
force vital capacity is measure when the patient is ecxhating with maximal speed and effort
Smoking decreases vital capacity.
there is no difference.
the vital capacity of lungs is 3.5 liters to 4.5 litres
vital lung capacity is how much air remains in your lungs after you exhale
Vital capacity is the maximum amount of air you can breathe out after breathing in (Nelson Physical Education VCE Units 1 &2) A vital capacity is measured by SPIROMETER.
bigger body surface area = bigger vital capacity
One measure of lung size is called vital capacity and it refers to the amount of air that can be inhaled and exhaled forcibly in one breath.
A teenage girl will likely have the same vital capacity as an adult woman. About 5 to 6 liters of air would be the vital capacity for a 15 year old female.
higher vital capacity should help them to go to high pitch
The vital capacity is the maximum amount of air that a person can expel from the lungs.
Exercise increases vital capacity because the lungs need more oxygen to supply the muscles with vital nutrients and the tougher the exercise the more nutrients needed. the lungs expand during this to account for the extra need hence increasing the vital capacity
Vital capacity can be decreased because of smoking. Smoking can cause emphysema which is a disease that makes it very hard to breathe.
My tidal lung capacity was lower. I know the difference because in the tidal lung capacity you are taking in less breath. When you are doing the vital lung capacity, you take in more breath.
No, vital capacity is the maximum volume a person can exhale after taking the deepest breath that they can
The increased residual volume and decreased vital capacity indicates difficulty in breathing. There are many conditions that can make the breathing capacity to reduce.
You can use balloons to measure lung capacity.
Vital capacity is a manuever performed to measure the amount of air that your can take in until you feel that you absoslutely can't inhale anymore and then exhale fully. Residual volume is the amount of air left in the lungs after you exhale no matter how much you blow out. This is what helps to keep the alveoli open. and Total lung capacity is the combination of the two of them. VC + RV=TLC
