Spirometery measures the airflow through lungs to check how your lungs are performing. This specific test measures how much and how fast a person can move air into and out of lungs. It helps to diagnose asthma, chronic obstructive pulmonary disease (COPD), and other illnesses affecting breathing. It is a simple test done in our facility and takes a few minutes. The patient breaths into a mouthpiece which is connected to a computer. During the test, patient will be breathing in and out as instructed. The computer will measure the amount and speed of air patient breaths in and out of lungs.
