home help: How do you measure your lung capacity at home? - Help.com

I use this thing called a peak full meter. It is designed to allow someone with asthma to know how bad their breathing is. You exhale as fast as you can and it shows you how much breath you have.

Large balloon, and a volume measuring device… Could possibly be able to measure volume by diameter of balloon? If it’s a round one, it might be possible, I know there’s an equation for spheres.

Mind you it won’t be accurate though.

Blow up a balloon, put in tub of water, measure how much water height changes, calculate volume difference, ta-da, eureka :)

Oh, smarter idea than mine =)

I’m not sure how you’re measuring the smartness capacity of these ideas, but I do notice at least a few words of coincidentality. minus the 4, divide by 16, and ummm … (hold on I’ll be back, I’ve got to think about this…)

Well, I don’t think you really need calculations with the water thing, cause the volume in the balloon displaces the same volume as in the tub, doesn’t it?

not if it pops

It shouldn’t pop if you don’t stick a pin to it? :P

I guess if you completely filled a container with water and had another container under it and put something in the first container then all the displaced water would be collected in the second container and you could easily measure it by drinking it and then weighing yourself.

LOL! Or you could just weigh the container before the water went in, weigh the whole container with water spilled in, and subtract? Oh wait, math there…

Pour the water into a measuring flask/ beaker/ something?

If he doesn’t own a balloon then none of this advice will help.
I’ll check back later.

A balloon can easily be bought! Or stolen! Err… It’s like taking candy from a baby… Maybe not so easily…

Night =)

Its called a peak flow meter. They’re readily available at most chemists. Usually used by COPD patients.

sorry are you trying to measure your lung volume ? its usually done on a spirometer but if you want the Blue Peter easy way:

1) Get a straw with a bendy end, a large measuring jug, and a big bowl of water

2) fill the jug and the bowl with water. put the jug in the bowl upside-dowing, being sure not to let any air get in the jug

3) dip your straw under the jug, and blow. then read off the measurement on the measuring jug.

Get a LARGE bowl of water, easiest. Put the measuring jug inside the bowl, fill it with water, turn it upside down with the rim of the jug UNDER water level, and TA DA!

Yeh, basically the bowl would have to be a bath tub
