what is spirometer

A spirometer is an apparatus used to measure the volume of air inspired and expired by the lungs. It measures ventilation, which is the movement of air into and out of the lungs. A spirometer is the main piece of equipment used for basic Pulmonary Function Tests (PFTs) . It is used to diagnose lung diseases such as asthma, bronchitis, and emphysema, and to rule out other conditions that affect breathing. Spirometry is also used to monitor lung conditions and check whether a treatment for a chronic lung condition is helping the patient breathe better. During a spirometry test, the patient breathes into a tube attached to a machine called a spirometer. The spirometer measures the amount of air the patient inhales, exhales, and how quickly they exhale. The test is repeated several times to ensure accurate results. A spirometer can be used in a doctors office or a special pulmonary function testing lab. There are different types of spirometers, including conventional spirometers, body plethysmographs, pneumotachometers, and fully electronic spirometers. An incentive spirometer is a different type of medical device that helps the lungs expand and get stronger.
