Allergy Crystal Lake - Fan Choice Aword Dr. Askenazi

Doctor near Northbrook discusses the common cold, lung function tests to detect a range of respiratory conditions

Your pulmonary system is well orchestrated. The organs and tissues responsible for moving oxygen in and carbon dioxide out operate in harmony. A measure of how well this system works is lung function. Some medical conditions interfere with the way the air moves in and out of the lungs.

Some of the conditions that can affect the proper balance necessary for good pulmonary function include:

  • Asthma
  • Emphysema
  • Scleroderma
  • Sarcoidosis

Performing lung function tests helps to give Advanced Allergy & Asthma Associates and Food Allergy Center of Illinois clues as to what is affecting your lung functioning and breathing. Drs. Askenazi and Hahn use spirometry, a device popular in lung testing. The spirometer is a machine that measures how much air enters the lungs, as well as how much air is quickly forced out of the lungs.

To perform the test, you will breathe into a tube connected to the spirometer. The doctors will give you instructions as to how to breathe and how fast to inhale and exhale. Each of these instructions corresponds to a different measurement, such as forced vital capacity (the volume of air that is exhaled after deeply breathing in). All of these measurements help Drs. Askenazi and Hahn test for a range of respiratory disorders of varying severity.

For instance, many respiratory infections may be detected with lung function tests. The common cold is one of many acute upper respiratory infections. While the common cold can make you feel poorly for a few days, it is not without potentially more severe complications such as sinusitis. Secondary infections such as strep throat and pneumonia can develop.

On another note, lung function tests are generally more helpful to our specialists if they are performed when you do not have a cold. In fact, an acute respiratory infection such as a cold is considered a contraindication. It is important to discuss all medications you may be taking, as some can interfere with the accuracy of the results.

To find out more about lung function tests and if your symptoms may be more than the common cold, call your allergy and asthma specialists near Northbrook at 847 888 8802.
