“…When lung function is normal, there is no difference of lung volume values measured by these two methods. However, in the setting of airflow obstruction, the values measured by these two methods are heterogeneous8910. The guideline of American Thoracic Society/European Respiratory Society (ATS/ERS) on lung volume measurements has not provided a clear statement on recommending one specific technique over the other6.…”

Chronic obstructive pulmonary disease (COPD) is a chronic airway disease characterized by persistent airflow limitation. Moreover, lung hyperinflation evaluated by lung volumes is also the key pathophysiologic process during COPD progression. Nevertheless, there is still no preferred method to evaluate lung volumes. For this study, we recruited 170 patients with stable COPD to assess lung volumes stratified by airflow limitation severity. Lung volumes including residual volume (RV) and total lung capacity (TLC) were determined by both body plethysmography and helium dilution methods. The discrepancies between these two methods were recorded as ΔRV%pred, ΔTLC%pred, and ΔRV/TLC. We found that ΔRV%pred, ΔTLC%pred, and ΔRV/TLC increased significantly with the severity of COPD. The differences of lung capacity between these two methods were negatively correlated with FEV1%pred, and diffusing capacity for carbon monoxide (DLCO%pred). Moreover, the receiver operating characteristic (ROC) for ΔTLC%pred to distinguish severe COPD from non-severe COPD had an area under curve (AUC) of 0.886. The differences of lung volume parameters measured by body plethysmography and helium dilution methods were associated with airflow limitation and can effectively differentiate COPD severity, which may be a supportive method to assess the lung function of stable COPD patients.

“…Numerically, the absolute change was two-fold higher than baseline measurements. Collectively, these changes can be explained by the post-surgical improvements in compliance of the pulmonary tissue, thoracic cage, and airway resistance, given that pulmonary volume is compromised proportionally to tumor size [12,13]. We acknowledge that total lung capacity was not measured in our patients in order to confirm a restrictive ventilatory pattern.…”

“…As this condition worsens, accessory muscles of inspiration are activated generating a more pronounced decrease in the intrapleural and alveolar pressure that enables the movement of airflow. As a consequence, energy expenditure increases, triggering the appearance of symptoms such as chest pain and fatigue [13].…”

Solitary fibrous tumors of the pleura (SFTP) represent less than 5% of all pleural tumors with a higher susceptibility for men in the sixth and seventh decades of life. Imaging and histopathological analyses indicate that these tumors have an unpredictable clinical course since larger tumors are often associated with malignancy; however, this assumption is not universal. In addition, there are no systematic descriptions of lung function in either the basal or post-surgical scenarios of SFTP patients. We describe a series of 3 patients between 4 th and 5 th decade of life with a benign histopathological SFTP without local recurrence in their follow-up. We also analyzed changes in lung function, emphasizing possible associations with clinical recovery.

RESUMEN.La pletismografía corporal (PC) es una prueba de función respiratoria que mide la capacidad funcional residual (FRCpleth) y la resistencia específica de la vía aérea (sRaw). La PC es el estándar de oro para la medición de volúmenes pulmonares. Los resultados son útiles para confirmar la presencia de restricción pulmonar. Además, en las enfermedades obstructivas permite cuantificar la hiperinflación pulmonar y el atrapamiento aéreo. El propósito de este documento es describir el procedimiento que de forma estandarizada se sigue en el Laboratorio de Fisiología Respiratoria del Instituto Nacional de Enfermedades Respiratorias Ismael Cosío Villegas en la Ciudad de México. Este documento se apega al estándar mundial vigente; no obstante, hacemos algunas recomendaciones prácticas para la realización e interpretación de la prueba que esperamos sean de utilidad al lector.Palabras clave: Pletismografía corporal, procedimiento, función pulmonar, volúmenes pulmonares, resistencia específica de la vía aérea.ABSTRACT. Body plethysmography (BP) is a pulmonary function test that measures functional residual capacity (FRCpleth) and specific airway resistance (sRaw). BP currently constitutes the gold standard for measuring pulmonary volumes. Results of this test are effective in confirming the presence of pulmonary restriction, while in cases of obstructive disease they permit quantification of pulmonary hyperinflation and air trapping. The objective of this manuscript is to describe the standardized procedure for BP testing followed at the Respiratory Physiology Laboratory at Mexico City's National Institute of Respiratory Diseases (Instituto Nacional de Enfermedades Respiratorias Ismael Cosío Villegas). While respecting current international standards, the article includes some practical recommendations for performing and interpreting this test that we hope readers will find useful.
