Spirometer: Spirometry is a test

Spirometry is a test that measures airflow into and out of your lungs. It can help diagnose lung diseases such as COPD, asthma, and restrictive lung disease. Learn how to prepare, what to expect, and how to interpret your results. A spirometer is defined as a biomedical device that measures lung capacity and volume. Its construction is simple, consisting mainly of a gas-collecting container. Read the instructions associated with your spirometer for more information. Some meters need to be returned to the manufacturer for a repair if the calibration is out. It is considered optimal for spirometric values to be checked on a weekly basis using a biological control (a healthy person working in your team) [3]. Patient positioning:
