Add to My Toolkit
Description

The American Thoracic Society (ATS) and the European Respiratory Society (ERS) Task Force recommendations for standardisation of the measurement of lung volume testing outline how to obtain measurement of functional residual capacity (FRC) using body plethysmography, nitrogen washout, helium dilution, and imaging techniques. In addition, this source contains details regarding the assessment of total lung capacity (TLC), vital capacity (VC), reserve volume (RV), expiratory reserve volume (ERV), and inspiratory capacity (IC).

These recommendations for standardization of the measurement of lung volume testing are part of a series of recommendations by the ATS/ERS Task Force for the standardization of lung function testing, which can be found on the ATS website at www.thoracic.org/statements/pulmonary-function.php. Detailed information regarding patient preparation is included in the general considerations document for lung function testing in this series.

Specific Instructions

A comprehensive evaluation of lung function requires investigation of various aspects of the lung, such as lung volumes and diffusion capacity. Hence, the American Thoracic Society (ATS) and the European Respiratory Society (ERS) Task Force have published a series of documents regarding pulmonary function testing. The Sickle Cell Disease: Cardiovascular, Pulmonary, and Renal Working Group recommends researchers access the ATS website (www.thoracic.org/) to view other documents in this series that may apply to their area of research.

Additionally, although there are various methods to measure functional residual capacity (FRC), the Working Group views body plethysmography as the most accurate, particularly when airflow obstruction is a possible underlying condition.
