A pilot comparison of helium dilution and plethysmographic lung volumes to assess the impact of a long-acting bronchodilator on lung hyperinflation in COPD
Résumé
Currently, two methods for measuring TLC, RV, and FRC are used in clinical pulmonary function laboratories: body plethysmography and helium dilution. However, these methods are not interchangeable. In moderate-to-severe airflow obstruction, dilution method tends to underestimate and body plethysmography tends to overestimate RV.
