Protocol - Lung Function - Lung Volume

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.

The procedure is explained, emphasizing the need to avoid leaks around the mouthpiece during the washout and using a nose clip; 5) The patient breathes for ~30-60 seconds on the mouthpiece to become accustomed to the apparatus and to ensure a stable end-tidal expiratory level; 6) The patient is turned 'in' (i.e. connected to the test gas) at the end of a normal tidal expiration; 7) The patient is instructed to breathe regular tidal breathes; 8) The O2 flow is adjusted to compensate for O2 consumption (significant errors in the calculation of FRC can result in O2 consumption is not adequately accounted for); 9) The helium concentration is noted ever 15s; 10) Helium equilibration is considered to be complete when the change in helium concentration is <0.02% for 30 seconds.

A change in inspired N2 of >1% or sudden large increases in expiratory N2 concentrations indicate a leak; hence the test should be stopped and repeated after a 15-minute period of breathing room air.

In patients with severe obstructive or bullous disease, the time between trials should be >= 1 hour.

Measure Name:

Lung Function - Lung Volume

Release Date:

July 30, 2015

Definition

Clinical assessment to determine the volume of gas within an individual’s lung.

Purpose

This measure can be used to differentiate obstructive and restrictive pulmonary conditions and to detect and quantify symptoms associated with conditions that impact the lung, such as sickle cell disease, cystic fibrosis, and obstructive airway disease.
