Respiratory Research Journal published a study on the importance of Airway resistance (RAW) and specific airway conductance (sGAW) measurements through body plethysmography. This study, based on 975 patients tested, investigated the contribution of RAW and sGAW to a diagnosis of obstructive airways disease and their role in differentiating asthma from COPD. The results show "sGAW to be a significant...

A new study has been published in the Turkish Thoracic Journal reviewing the available techniques for the measurement of lung function in preschool children. This study focuses on two different techniques that can be used in clinical practice, such as the interrupter technique and the forced oscillation technique. For both techniques, normal values measured in large populations of healthy children...

A new study published on the Journal of Cancer Research and Therapy focuses on the relationship between COPD and lung cancer. The aim of this study is to develop a clinical prediction model of contribution of chronic obstructive pulmonary disease (COPD) to the pathogenesis of lung cancer, by reporting the estimated prevalence and severity by GOLD criteria in a single-institution cohort of patients...

Quark PFT with the new X9 multi-use pneumotach performed with acceptable accuracy versus Spirometry and DLco simulators at the Hans Rudolph facilities of Shawnee, Kansas (USA) in 2011. Quark PFT with X9 pneumotach was validated at Hand Rudolph Inc. laboratories against a Flow Volume Simulator (HRI FVS 1120 series generating the standard ATS/ERS 24 Volume-Time waveforms for the parameters FVC, FEV1,...
