The accuracy level of three different lung volumes techniques (body plethysmography, radiography with computerized tomography and dilution) were analyzed in the "Respiration - International Journal of Thoracic Medicine". Accurate measurement of lung volumes is of paramount importance to establish the presence of ventilatory defects and give insights for diagnostic and/or therapeutic purposes. The...

The clinical usefulness of Forced Oscillation Technique has been investigated in a scientific article published in Paediatric Respiratory Reviews Journal. The Forced Oscillation Technique (FOT) is a lung function modality based on the application of an external oscillatory signal in order to determine the mechanical response of the respiratory system. The method is in principal noninvasive and...

The prognostic importance of lung diffusion capacity testing in pulmonary hypertension patients has been analysed in this study published in the Journal of the American College of Cardiology. This study sought to investigate the prognostic importance of a low diffusion capacity of the lung for carbon monoxide (DLCO) in patients with a catheter-based diagnosis of pulmonary hypertension due to heart...

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...
