An incentive spirometer is a handheld medical device that measures the volume of your breath. Your doctor, surgeon, or nurse will give you specific instructions on how to use it. Share on ...

careful when measuring their volume using the water displacement method. Also, it is difficult to measure the volume of the smallest rod. Give students a hint that it is between 1.5 and 2.0 mL.

Volume displacement spirometers Conventional spirometers provide a direct measure of expired volume from: displacement of a bell (water sealed), piston (rolling seal) or bellows (wedge bellows).

Volume is a measure of the amount of space an object takes up. When a cylinder is submerged in the water it pushes water out of the way. If you measure the amount the water level increases, you can ...
