“…Note that there is no requirement for a minimum FET. Studies have shown that patients with airflow obstruction and elderly patients may have difficulty meeting the 2005 ATS/ERS requirement of achieving a plateau ( 77 – 79 ), and the criterion results in the exclusion of too many patients while having minimal impact on predicted values ( 80 ). A large occupational health study in an older population (mean age, 63 yr) found that 53% of spirometry maneuvers failed to reach a plateau despite encouragement by trained operators and long FETs ( 72 ).…”

Background: Spirometry is the most common pulmonary function test. It is widely used in the assessment of lung function to provide objective information used in the diagnosis of lung diseases and monitoring lung health. In 2005, the American Thoracic Society and the European Respiratory Society jointly adopted technical standards for conducting spirometry. Improvements in instrumentation and computational capabilities, together with new research studies and enhanced quality assurance approaches, have led to the need to update the 2005 technical standards for spirometry to take full advantage of current technical capabilities. Methods: This spirometry technical standards document was developed by an international joint task force, appointed by the American Thoracic Society and the European Respiratory Society, with expertise in conducting and analyzing pulmonary function tests, laboratory quality assurance, and developing international standards. A comprehensive review of published evidence was performed. A patient survey was developed to capture patients’ experiences. Results: Revisions to the 2005 technical standards for spirometry were made, including the addition of factors that were not previously considered. Evidence to support the revisions was cited when applicable. The experience and expertise of task force members were used to develop recommended best practices. Conclusions: Standards and consensus recommendations are presented for manufacturers, clinicians, operators, and researchers with the aims of increasing the accuracy, precision, and quality of spirometric measurements and improving the patient experience. A comprehensive guide to aid in the implementation of these standards was developed as an online supplement.

“…The 2005 ATS/ERS requirement of a minimum FET ( 1 ) resulted in some valid maneuvers being classified as inadequate ( 77 , 78 , 85 ). In a study of 1,631 healthy children aged 10–18 years, only 18% met the 2005 minimum FET in maneuvers that were visually judged to be acceptable ( 73 ).…”

“…Because spirometry relies on patient compliance and maximum effort, it is particularly prone to a number of acquisition pitfalls. A mouthpiece air leak or obstruction, patient cough, or early glottis closure can cause artifacts, and inadequate initial inhalation, poor expiratory effort, and premature termination of expiration can cause spirometric tracings that fall short of minimum quality and reproducibility standards (8). Clues to inadequate quality are irregular tracings, failure to achieve reproducible curves and values across multiple attempts, and premature cessation of exhalation ( Fig 3).…”

Pulmonary Function Tests for the Radiologist

Pulmonary function tests (PFTs) provide important quantitative information about lung function and can be used to elucidate pathologic conditions responsible for respiratory symptoms, assess the severity and course of disease, and evaluate the patient for suitability and timing for lung transplantation. They are typically used in tandem with chest imaging, along with other ancillary data, to arrive at a specific diagnosis. PFTs may provide the radiologist with clues to the diagnosis and grading of a wide variety of pulmonary diseases. In this review, the authors discuss the clinical use of PFTs, their major components, and important measurements and graphical representations that are essential for understanding and interpreting the results. The key components of PFT panels-static lung volumes, dynamic lung function (spirometry), and diffusion capacity-are explained. The authors present a general algorithmic approach for problem solving, with recognition of common patterns of results (obstructive, restrictive, mixed, nonspecific, and normal). Pulmonary diseases from each of the major patterns and chest imaging are illustrated, and correlations between particular PFT results and disease severity and morphology at imaging are examined. Common pitfalls encountered during interpretation are also highlighted. A basic understanding of the mechanics of PFTs, characteristic patterns in important diseases, and correlation between lung function and imaging findings may assist the radiologist in diagnosis and follow-up of key pulmonary diseases and strengthen the radiologist's role as part of a multidisciplinary diagnostic team. Online supplemental material is available for this article. RSNA, 2017.

“…Ventilation is one of the main functional lung parameters and is used to evaluate the progression of lung diseases and response to therapy. Spirometry offers a wide range of static and dynamic ventilation parameters, but shows an operator and subject dependent repeatability . Especially, the lack of regional information demands for better alternatives.…”
