Pulmonary Function Tests Harpreet Ranu, Michael Wilde, Brendan Madden Accepted 16 December 2010 AbstrAct Pulmonary function tests are valuable investigations in the management of patients with suspected or previously diagnosed respiratory disease. They aid diagnosis, help monitor response to treatment and can guide decisions regarding further treatment and intervention. The interpretation of
The second goal of pulmonary function testing is to quantify the severity of a physiologic derangement. 3 Usually this requires comparing the measured value to a predicted or reference value, but the actual quantification is often done in a somewhat arbitrary fashion.

Lung function tests, also called pulmonary function tests or breathing tests, are tests that can be done to find out how well your lungs and airways are working. Lung function tests can help in the diagnosis of respiratory (breathing) conditions, work out how severe a condition is, and help monitor the response to treatments.

Pulmonary Function Testing Case Questions and Answers

normal value indicates either a restrictive or a normal pattern. If the FEV 1/FVC ratio is normal, a low forced vital capacity value indicates a restrictive pattern, whereas a normal value indicates a normal pattern. Pulmonary function tests are not generally indicated in patients without symptoms, and they may be confusing when nonpulmonary diseases that affect the pulmonary system are active
If pulmonary function test results are normal but the physician still suspects exercise- or allergen- induced asthma, bronchoprovocation (e.g., methacholine challenge, mannitol inhalation challenge, exercise testing) should be performed.

In a diagnosis of COPD, pulmonary function tests are performed to assess lung function and determine the degree of damage to the lungs. In addition to a patient’s history and physical, lung imaging studies (chest X-ray and CT scan), and PFTs are critically important in evaluating respiratory health.
Pulmonary function tests must always be analyzed within the context of the patient being tested. Age, height, weight, race, and sex directly affect the results which one would predict for a given individual. Diseases which the patient may have or drugs which they are taking may be important in the interpretation of the patient’s test. For instance, in a patient taking gold shots for rheumatoid

Prevalence of Supranormal Pulmonary Function Test Values

Pulmonary Function Tests (PFTs) for Health Care Professionals Pulmonary function tests (PFTs), including spirometry, lung volumes, diffusing capacity, and airway resistance, are breathing tests led by a trained pulmonary function technologist, usually done at a hospital or clinic, but increasingly done at a physician’s office.
Lung function tests are used in clinical practice to detect “abnormality” against a background of “normal” function. “Abnormality” may be determined either by (i) detection of some discrete abnormality (eg, the shape of the flow volume loop) or (ii) by the use of reference values to show

What is a Pulmonary Function Test? 1.0 Introduction. Pulmonary Function testing measures the function of lung capacity and lung and chest wall mechanics to determine whether or not the patient has a lung problem. Pulmonary Function Tests are commonly referred to as “PFTs”. When a patient is referred for PFT’s, it means that a battery of tests may be carried-out including: simple screening
Like most medical observations, reliable interpretation of pulmonary function results relies on the availability and use of appropriate reference data to help distinguish between health and disease and to assess the severity and nature of any functional impairment.

Pulmonary function testing (PFT) is a common screening method for ILD. However, some SSc patients with entirely normal PFTs have ILD evident on their HRCTs. Our aim was to assess the performance characteristics of PFTs for the diagnosis of ILD in patients with early dcSSc, using HRCT as the reference standard.
