A spirometer is an instrument that measures the capacity of the lungs indicating the volume and speed of air breathed in and out. The purpose of using a spirometer is to check the health and functioning of the lungs.
During a spirometry test, the customer is asked to breathe into the mouthpiece attached to the spirometer. The device measures the rate at which air is inhaled and exhaled as well as the lung capacity thus determining the speed/flow and volume/amount of air breathed in and out. The measurement unit is FEV1 which is Forced Expiratory Volume in One Second.
An incentive spirometer determines how deeply one can inhale and is generally used during treatment of lung conditions such as pneumonia. The test involves taking in slower, deep breaths for expanding and filling the lungs with air.
Incentive spirometer has a breathing tube, an air chamber as well as an indicator. The breathing tube is attached to the air chamber with a mouthpiece at the end. The indicator can be found inside.
