Pulmonary Function Test

The respiratory function test, which is used to objectively measure the capacity and functional status of the lungs, is carried out in our hospital under the supervision of a specialist physician. Respiratory function tests are performed with devices called spirometers. In other words, with this test, the air volume that the lungs can take and the air flow rate created by the strong breathing activity performed during the delivery and delivery of this air to the lung can be measured. These two parameters give extremely important clues in the diagnosis of many diseases. For example, in patients with Asthma or COPD (Chronic bronchitis, emphysema), it is determined that there is a decrease in the flow rates measured during a very strong and rapid breathing after completely filling the lungs with air, and according to this decrease rate, the disease can be diagnosed as well as the severity of the disease. determines. In addition, the success of the treatment and the course of the disease can be monitored concretely through the pulmonary function tests performed in the follow-up of these patients. On the other hand, in the presence of lesions occupying space in the lung tissue, or in the presence of destructive diseases in the lung tissue, in the diseases that cause lung edema, such as heart failure, the maximum air volume that the lungs can receive decreases.

How are respiratory function tests performed?

During the test, the patient is in a sitting position. The nose is closed with a plastic latch and breathing through the nose is prevented. The patient breathes easily through a disposable cardboard mouthpiece, which is used only by himself, at the end of the device. Depending on the nature of the test, the physician or technician who performs the test makes the test maneuvers by asking the patient to breathe deeply, to exhale very quickly and to the end, or to hold his breath for a short time. The result of the test is taken immediately after these maneuvers are completed and the results are interpreted by the thoracic specialist.



In what cases are pulmonary function tests performed?

1. In the presence of shortness of breath, wheezing, cough,

2. In order to support the diagnosis suspected according to examination findings and chest radiography,

3. To investigate the effects of congenital or subsequent deformities in the chest on breathing,

4. In order to monitor the progress of the disease and the effectiveness of the treatment of diagnosed COPD, asthma, heart failure, and respiratory muscles.

5. In order to assess disability due to respiratory disease,

6. Screening of people and groups at risk for lung disease (For example, smokers, miners, workers who breathe harmful gases in their environment),

7. Pulmonary function tests are carried out in order to determine the risks of general anesthesia and surgical respiratory complications in advance and to take necessary precautions in the preoperative period.
