Spirometers are used in doctor's offices to test lung capacity and to diagnose such issues as chronic obstructive pulmonary disease (COPD), asthma, and other breathing conditions. They are also used as a diagnostic tool for those who are being treated for lung conditions. The air that in inhaled and exhaled is measured on how fast it moves through the lungs.
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 inhaled medications will be used after the first test to open the lungs, a 15 minute break is advised before administering the next test. The tests can then be compared to see if the administered medication has improved the flow of air through the lungs. The tests typically take less than 15 minutes in total to administer. Measurements of the most amount of airflow exhaled, called forced vital capacity (FVC), as well as how much air is exhaled in a second, referred to as forced expiratory volume (FEV-1), are recorded.
This test is used to detect respiratory disease in patients who present symptoms of breathlessness, to diagnose and manage asthma, and to distinguish respiratory conditions from those of cardiac disease. It is used to differentiate between obstructive and restrictive lung disease, measure bronchial responsiveness, identify risk of pulmonary barotrauma in scuba divers, and assess impairment from occupational asthma. Risk assessment before anesthesia or cardiothoracic surgery can be measured as well as detection of vocal cord dysfunction and the ongoing treatment of existing lung conditions.
Patient cooperation is required for accurate results, it can be used on children who understand the instructions of what they need to do which is usually the age of 6 or older. It is not a test that can be done on patients who are unable to understand the instructions, are unconscious, have limitation of respiratory efforts, or are heavily sedated.
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.
