Pulmonary Function Lab
Pulmonary function tests (Spirometry, lung volumes and diffusion capacity) are a group of tests that measure how well the lungs take in and release air and how well they move gases such as oxygen from the atmosphere into the body's circulation.
common test used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and certain other conditions that affect breathing. Spirometry may also be used periodically to check how well your lungs are working once you're being treated for a chronic lung condition.
measurement that detects restrictive lung diseases. In this set of diseases, a person cannot inhale a normal volume of air. Restrictive lung diseases may be caused by inflammation or scarring of the lung tissue (interstitial lung disease) or by abnormalities of the muscles or skeleton of the chest wall.
(also called the DLCO) estimates how efficiently the lungs transfer oxygen from the air into the bloodstream.
HAST (High Altitude Simulation Test)
Results from this test enable the physician to predict oxygen needs during air travel.
A study performed to determine if a patient has a lack of response to supplemental oxygen.
Respiratory Muscle Strength
(MIP MEP) this test is designed to evaluate those muscles of breathing. The test is often called MIP/MEP - maximum inspiratory and expiratory pressure.
Bronchial Provocation Tests
When the physician assessing a patient is concerned that they might have asthma, first spirometry is performed. If no obstruction is identified further testing is sometimes required using the following methods:
• Mannitol Challenge
• Exercise Induced Bronchospasm
• Cold Air Challenge
medication used to ‘provoke' airway response. When the airways of people with asthma are exposed to this medication, it will stimulate a response, which can be measured. If there is a positive response, asthma can be clearly identified and treated appropriately.
Exercise Induced Bronchospasm
A test used to see how exercise affects your lung function. With this test, your doctor may have you do a lung function test before and after you exercise. Exercise is usually done for six to eight minutes on a treadmill or other stationary workout machine.
Cold Air Challenge
A test designed to measure airway responsiveness to cold dry air.
Airway Resistance Measurements
Used for evaluation of airway responsiveness, provocation testing, characterization of various types of obstructive lung disease, localization of the primary site of flow limitation, and evaluation of localized obstruction. This can be measured using the following:
• Body Plethysmograph
• Impulse Oscillometry
