Results: This document presents a reporting format in test-speci c fi units for spirometry, lung volumes, and diffusing capacity that can be assembled into a report appropriate for a laboratory’s practice. Recommended reference sources are updated with data for spirometry and diffusing capacity published since prior documents.

Quality control Three acceptable maneuvers with repeatable values: Two highest values of FVC and FEV1 should be within 150mL (100mL if FVC ≤ 1L)

The American Thoracic Society Committee on Proficiency Standards for Pulmonary Function Laboratories (ATS PFT Committee) has been concerned about the wide variability in pulmonary function test (PFT) reports among laboratories and has discussed the need for a more standardized format, to include information to assist accurate interpretation and ...

Repeatability is the closeness of agreement between the results of successive measurements of the same item carried out, subject to all of the following conditions: same method, same observer, same instrument, same location, same condition of use, and repeated over a short space of time.

PFT: Defining Normal Values Interpreting PFTs requires comparing obtained values to reference values (GLI, NHANES III, LLN, fixed ratio), which are dependent on age, gender, race and ethnicity, and height.7

Guidelines for PFT interpretations Reproducibility and technique of the patient—there will be comments by the technicians as to effort of the patient and reproducibility is judged by having three maneuvers within 5% of each other.

Understand the physiology of the core pulmonary function tests: spirometry, lung volumes and DLCO Apply an organized approach to interpreting pulmonary function tests Identify obstructive, restrictive, mixed obstructive-restrictive and pulmonary vascular patterns of abnormalities on pulmonary function testing.

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.
