RESPIRATORY FUNCTION TESTS
Our patients who applied to the doctor because of their complaints know that their radiographs and blood sputum examinations will be performed during the diagnosis and treatment process. They are not familiar with the concept of respiratory function testing.
Pulmonary function tests laboratories are the laboratories where our patients have little information.
The purpose of this small leaflet is to inform you, our patients, about it.
In the respiratory function tests laboratories, some electronic and non-electronic instruments that the patient directly contacts are not those that the patient has seen before.
Blood, sputum, urine and similar materials are sent to the laboratory, the patient does not see the device from which the tests are performed, the technician who does it. The results are sent to him in writing.
An important feature of the respiratory function laboratory is the one-to-one establishment of the patient, technician and instrument relationship. These methods are foreign to you, our patients.
WHAT IS MEASURED IN THE RESPIRATORY FUNCTION TESTS LABORATORY?
In the respiratory function tests laboratory; The volume (volume) of air entering and exiting the lungs is measured at rest, during difficult breathing and exercise, and compared with values obtained from the person of the same age, sex, height, and the values obtained from the person being tested.
The air entering the lungs reaches the lungs at a certain speed in the airways. When the roads are narrowed in traffic, the speed of the vehicles flowing here decreases. When the respiratory tract is narrow, the air velocity entering and exiting decreases. To show it. With our lungs fully loaded, the maximum amount of air (FEV1) removed in the first 1 second is measured.
If the velocities we measured are low, we also measure whether the velocity increases with the given breath expanding (bronchodilator) medications . This test is called reversibility test.
Although there are complaints, function tests may be normal in some of our patients. We investigate the speed reduction that may occur in the respiratory tract with substances that can replace harmful substances such as smoke and dust that cause complaints of our patient . This test is called bronchial reactivity test (Provocation test, respiratory hypersensitivity test).
The resistance caused by the stenosis, which causes the speed of the gases entering and exiting the lungs to decrease, is measured.
Our lungs play an important role in transporting oxygen from the air into the blood. When we breathe, the gases in the air reach our air sacs (alveoli). Oxygen is rapidly transferred to the red blood cells in the vessels in the wall of these very thin walled vesicles. The carbon dioxide in red blood cells moves in the opposite direction and passes to our air sacs. This gas exchange process is called diffusion. In the respiratory function laboratory, it is determined whether the lungs have adequately exchanged oxygen and carbon dioxide by diffusion measurement.
While breathing in, we use our muscles belonging to our rib cage, abdomen, neck and shoulders. These muscles build strength and help us breathe and exhale. By measuring the pressures created by these muscles while breathing (inspiratory) and exhaling (expiration) , information about respiratory muscle functions is obtained.
WHO IS RESPIRATORY FUNCTION TESTED?
those who have shortness of breath, wheezing, cough, sputum ,
-For those who have abnormal signs on the chest radiography, -For those who have been smoking for a long time , regardless of their complaints , -For those who will undergo
surgery under general anesthesia -Lung
, heart surgery,
-In another body of the body There
is the suggestion of diseases of our doctors patients thought to affect the lungs,
those working in jobs that affect -Akciğer of (miners, detergent, battery factory workers, bird feeders … .. etc),
-Lung they disease due exhilarating and inflammation, relieving in preventive medicine given medicines those whose effect is to be investigated.
Patients with myocardial infarction, aortic, brain aneurysm, eye pressure, uncontrolled hypertension, eye, thorax and abdominal surgery, and severe pain should inform the technician.
