Pulmonary function tests (PFTs) determine how well your lungs work. They determine how much air goes into and out of your lungs, how much air goes from your lungs to your blood and how well your lungs work during exercise.

2012年6月5日 · In this article we will provide an overview of basic pulmonary function tests and an algo-rithm for using and interpreting them, and then we use three cases to explain how to use these tests to identify the pattern of respirato-ry dysfunction, then make the diagnosis.

Pulmonary function testing is a group of tests that provide objective data on a patient's lung function. These tests must be interpreted within the context of the patient's history and physical examination, though their patterns can suggest different categories of respiratory disease.

2024年8月29日 · Pulmonary Function Testing (PFT) is a critical component in diagnosing, managing, and monitoring respiratory diseases, providing a comprehensive overview of lung function. These noninvasive tests measure various lung capacities, volumes, and flow rates, offering crucial insights into respiratory health and identifying abnormalities in lung ...

These tests evaluate lung volume, capacity, airflow rates, and gas exchange efficiency. The results help healthcare providers identify specific lung diseases, determine their severity, and monitor treatment progress.

Lung function tests can be used to: Compare your lung function with known standards that show how well your lungs should be working. Measure the effect of chronic diseases like asthma, chronic obstructive lung disease (COPD), or cystic fibrosis on lung function. Identify early changes in lung function that might show a need for a change in ...

2023年8月28日 · Pulmonary function tests (PFTs) allow physicians to evaluate the respiratory function of their patients in many clinical situations and when there are risk factors for lung disease, occupational exposures, and pulmonary toxicity.

The interpretation of lung function tests involves two tasks: 1) the classification of the derived values with respect to a reference population and assessment of the reliability of the data; and 2) the integration of the obtained values into the diagnosis, therapy and prognosis for an individual patient. ATS/ERS TASK FORCE:

Pulmonary function tests provide measures of airflow, lung volumes, gas exchange, response to bronchodilators, and respiratory muscle function. Basic pulmonary function tests available in the ambulatory setting include

2022年2月10日 · The pulmonary function test (PFT) is a diagnostic tool used to assess the functioning of the respiratory system. It provides valuable information about lung capacity, airflow, and gas exchange, helping healthcare professionals evaluate respiratory health, diagnose lung diseases, monitor disease progression, and assess treatment effectiveness.
