Doctors use spirometers to test air flow inhaled and exhaled through the lungs. This test is used for the diagnosis of breathing conditions such as chronic obstructive pulmonary disease, or COPD, and generally testing of lung capacity. It is also helpful in monitoring those who are being treated for existing lung conditions.
For those who are currently taking medication for a lung condition, the spirometer test can show the efficacy of the medications and show if there is improvement. A doctor will order this test if they suspect a patient has such conditions as COPD, chronic bronchitis, emphysema, asthma, or pulmonary fibrosis.
Prior to taking the test one will need to avoid using inhaled or other medications. Loose clothing should be worn that will not constrict the ability to take a deep breath and one should avoid eating a large meal before testing so that breathing will be easier.
A soft nose clip is worn to prevent air from escaping the nostrils and a filter will be placed over the mouthpiece of the instrument for sanitation purposes. The patient will be asked to take a deep breath and then exhale as hard as possible for a few seconds into the mouthpiece of the spirometer. This can cause shortness of breath or dizziness that will pass in a few moments. The test will be repeated a couple of times and the readings will be compared to make sure they are accurate and consistent.
Sometimes a person will be given inhaled medications after the first test to allow the lungs to open more. At least 15 minutes should pass before administering the second test. The tests will then be compared to see if there is an improvement in airflow. Overall the testing will take less than 15 minutes. The results will include a vital capacity (FVC) test to show the most amount of air that can be exhaled, and a forced expiratory volume (FEV-1) test to show how much air is exhaled in a second.
A spirometer test is used to diagnose and provide asthma management, detect respiratory disease for those who show symptoms of breathlessness, and to distinguish between respiratory conditions and cardiac disease. It can measure bronchial responsiveness or differentiate between an obstructive and a restrictive lung disease. It is used to assess the impairment from occupational asthma or identify risk from pulmonary barotrauma while scuba diving. It is also used for risk assessment before the administration of anesthesia or prior to cardiothoracic surgery. This test can measure the treatment of conditions that it detects and diagnose the dysfunction of vocal cords.
In order to get accurate results from this test the patient needs to fully cooperate with the instructions given. Children aged 6 years and over can take the test as long as they can follow the instructions. It will not work for those who are unconscious, are unable to understand the instructions, are heavily sedated, or have limited respiratory function.
Spirometers are an invaluable instrument for checking lung function while doing rigorous exercise, to check for hyper-responsiveness to the inhalation of either cold or dry air, for bronchial challenge testing, and when using medications such as methacholine or histamines.
