Who can perform a pulmonary function test?
Pulmonary function testing is usually done by a specially trained respiratory therapist or technician. For most pulmonary function tests, you will be asked to wear a nose clip to make sure that no air passes through your nose during the test. You will be asked to breathe into a mouthpiece that is connected to a machine called a spirometer. The technician may encourage you to breathe deeply during parts of the test to get the best results. Following all of the technician's instructions will help provide the most accurate results.

What is the function of a control in reducing sugar experiment?
The function of a control in any experiment is to give you something to test your results against. If you were to test for reducing sugars by using Benedict's test, not having negative or positive controls, that is tests where you know which is negative and which is positive, then you wouldn't have accurate results to compare to.

How To Prepare For Pulmonary Function Tests?
Pulmonary function tests are often used to diagnose lung disorders such as asthma, emphysema and bronchitis. They are also ordered by pulmonology specialists for determining the effects of prescribed medication. The most common pulmonary function tests include Spirometry and the Methacholine Challenge Test, which are usually used in diagnosing asthma. The spirometry test is a breathing test, which measures how much air the patient can exhale from their lungs and how fast they can do this. The test may require inhaling a bronchodilator medication before and after the test, that expands the airway. This allows air to pass through the airways more freely. The methacholine challenge test is done using a methacholine aerosol that is inhaled in increasing amounts before and after a spirometry test. The methacholine agent causes involuntary spasms of the airway if a breathing disorder such as asthma is responsible for the patient's symptoms. Following this test, the patient is administered a bronchodilator to stop and reverse the methacholine effects. When preparing for pulmonary function tests make sure to be aware of any colds or viral infections that have recently occurred. If there has been a recent viral infection or cold experienced, call and discuss this with the pulmonology specialist before the scheduled appointment. These illnesses could cause inaccurate test results. Also, inform the doctor of any recent immunizations as these also can interfere with results. The pulmonary specialist may want to reschedule the appointment. On the day of the test, do not drink cola, coffee or tea and do not eat chocolate. Patients should also avoid any exercise or strenuous activity on the day of the test and avoid exposure to cold air. Certain medications may also need to be temporarily discontinued until after the pulmonary function tests have been completed. Patients who use short-acting bronchodilator inhalers usually must stop using them for eight hours before tests are done. The pulmonary specialist will provide specific instructions to patients who presently take medications. Be sure to follow the doctor's medication instructions carefully when preparing for these tests and do not stop taking medications without the doctor's instructions. Patients should also avoid eating heavy meals before the test as some pulmonary function tests do require rapid breathing, which can cause lightheadedness and possible nausea. Do not smoke for at least 4 to 6 hours before these test and dress comfortably in loose clothing that allows for easy breathing while testing is done.
Asked in Pulmonary Health
Should you avoid caffeine before a pulmonary function test?
Generally, yes. Especially if the physician's office has asked you to not to take any pulmonary or cardiac medications. It really depends on which test they are having you do. Feel free to call your physicians office and ask a secretary or nurse, as they are usually more than willing to answer your questions.
