What are pulmonary function tests?

The PFT Test is the test used to assess how effectively your lungs are working and how healthy they are. They are additionally known as lung function tests. Pulmonary Function Test is the full name of the PFT test. These tests enable you to determine whether you are having any breathing problems and whether your lungs are adequately supplying oxygen to every cell in your body. These tests, such as the PFT for diagnosing asthma or the diagnostic test for lung cancer, must be undergone by patients with respiratory diseases or those who are suspected of having respiratory issues.

Types of pulmonary function tests

1. Spirometry

   Spirometry is a physiological test that gauges how well a person can breathe in and out over time. Spirometry is a test for the general condition of the respiratory system. Forced vital capacity (FVC) and Forced expiratory volume (FEV) are the primary outcomes of spirometry. Spirometry is a three-phase process: 1. Maximal inspiration 2. A "blast" of exhalation. 3. Continued complete exhalation to the end of the test. For spirometry, there are requirements for within-maneuver acceptability and between-maneuver reproducibility.

2. Lung volume measurement

   Plethysmography is a test that assesses the amount of air in the patient's lungs before and after a full expiration. When pulmonary fibrosis of a weak chest wall is suspected, this kind of pulmonary test is very helpful. The patient is instructed to breathe through a tube that is attached to a computer during plethysmography in order to quantify their lung volume. In some circumstances, doctors may advise patients to inhale nitrogen or helium gas and exhale it. The lung volume can be determined by the volume of the air.

3. Lung diffusion capacity

   A test known as lung diffusion capacity is performed to gauge how well the lungs are doing at transferring oxygen into the blood. Lung tissue function and the rate at which blood is pumped to the lungs can both be determined by the results of a lung diffusion capacity test. This test entails the patient inhaling a gas through a tube, holding their breath for a moment, and then exhaling the gas through the tube.

4. Oxygen level tests

   The level of oxygen in the blood is measured using oxygen level testing. A sensor is placed on a finger or ear during a painless test called pulse oximetry that calculates the amount of oxygen in the blood. In contrast, arterial blood gas tests need blood drawn from a wrist artery, which is then examined in a lab to determine the precise level of oxygen present in the blood.

5. Cardiopulmonary exercise test

   Cardiopulmonary exercise testing (CPET) is a specific exercise stress test used to assess your capacity for exercise and identify any potential causes of activity limitations. It is often carried out in a doctor's office or PFT lab on a treadmill or stationary bicycle.

6. Bronchial provocation test

   The sensitivity of your lungs is assessed with a bronchial provocation test. Asthma is frequently diagnosed or ruled out as the cause of symptoms using this method.

7. Exhaled nitric oxide test

   Like spirometry, an exhaled nitric oxide test requires you to breathe in deeply and then exhale fully into a mouthpiece attached to a monitor that measures the amount of nitric oxide in your breath.

   Exhaled nitric oxide testing, like spirometry, involves taking a big breath in and then completely exhaling into a mouthpiece connected to a monitor that counts the amount of nitric oxide in your breath.
