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.
Before the test is performed, patients who are on inhalant or other medications should skip using them during testing. Avoid eating a large meal so as to make breathing easier and wear loose clothing so that breathing will be unconstricted.
When taking the test a soft clip will be placed on the nostrils to keep them closed and filtered mouthpieces may be used to prevent the spread of germs. The patient will then take a deep breath and breathe out as hard as possible for a few seconds into a tube that is attached to the spirometer. Dizziness or shortness of breath may be felt shortly after doing this. The test may need to be repeated up to three times to get consistent and accurate readings.
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.
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.
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 can check for the effects of medication usage such as histamine or a methacholine agents, check the hyper-responsiveness to either inhalation of dry or cold air, or provide bronchial challenge testing. Some other lung tests that can be performed are a plethysmography or nitrogen washout.
