What is spirometry?

Spirometry is an extremely easy to perform pulmonary function test to be used to measure lung volumes, capacities and respiratory flow rates. In a patient/individual sitting upright, the mouthpiece of the test device is properly placed, the nose is latched. The patient breathes normally through the mouthpiece several times, then breathes deeply to fully fill his lungs, and after filling his lungs,immediately blows through the mouthpiece with all his might and as quickly as possible until almost he is out of breath. Immediately after the exhalation process is finished, a deep breath is taken and the test ends. The spirometry test is simple, but there are rules that must be followed. A properly performed spirometry test is a highly informative test. profdromerdeniz.com. Information about many clinical conditions such as upper airway obstruction, COPD, bronchial asthma, airway obstruction due to different reasons, pulmonary fibrosis could be obtained with spirometry test. In the following video you can see how a spirometry test is performed;

In individuals with airway obstruction detected by the spirometry test, a short-acting bronchodilator drug is administered, short time after the drug administration, a second test is performed to evaluate the difference. This test is called reversibility test. profdromerdeniz.com.
