SPIROMETRY

It’s a test to measure how fast and how much air can be exhaled and inhaled from your lungs. The results are helpful to see if the airways are narrowed. 

DIFFUSING CAPACITY

This test is used to assess the ability of the lungs to move gas from the airways into the bloodstream. It is helpful in determining the function of the alveoli (air sacs) in the lung tissue. 

PLETHYSMOGRAPHY
(LUNG VOLUMES)

Performed inside a clear glass booth, the test allows the total size of the lungs to be measured, as well as the volume of air that remains in the lungs after fully exhaling. 

 


EXHALED NITRIC OXIDE

Levels of this gas may be increased if a person has poorly controlled asthma and/or a strong response to inhaled particles. It is a useful tool to monitor the effectiveness of medications taken to treat asthma and allergy.


AIRWAVE OSCILLOMETRY

Small waves of air are passed into the lungs while a person breathes gently. Measurements of pressure and airflow that are measured give an indication of airway health and are particularly helpful when people are unable to manage the forceful blows required in Spirometry testing. 


BRONCHIAL CHALLENGE

If a clinical diagnosis of asthma has not been made with a person, this test can help assess the sensitivity of the airways and their likelihood of constricting with exercise or exposure to airborne irritants. For people with known asthma, it can help measure the level of control achieved with the current medications. 

 


ALTITUDE SIMULATION

All people have lowered oxygen levels when flying in commercial aircraft. It may be a problem for those with known lung disease and this test helps determine whether additional oxygen may be required in-flight for them to travel safely and comfortably.
