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,...
A new study shows for the first time the ventilatory response to exercise in COPD patients with emphysema. Sixteen patients with moderate to severe emphysema, quantified by high resolution computed tomography scan (HRCT), were studied. All participants underwent a full lung function evaluation with Quark PFT, including spirometry, diffusing capacity of the lung for carbon monoxide (DLCO) and body...
A study was presented during 2012 ATS validating the Rint measurements obtained with Rocc Pony FX option. The study, by the University of Florence (Italy) together with the University of Herston (QLD, Australia), aimed to establish whether the Rint measurements obtained with the Pony spirometry device are similar to those obtained with Microrint, a device that has been recently discontinued and...
A task force supported by the European Respiratory Society has recently developed the first evidence-based clinical practice guidelines for the diagnosis of asthma in children aged 5 to 16 years. Nine PICO (Population, Intervention, Comparator and Outcome) questions were used. The task force then developed a diagnostic algorithm based on the critical appraisal of the PICO questions, preferences...
The role of spirometry and forced oscillation technique (FOT) in asthmatic young patients has been investigated in a study published on the European Respiratory Journal. Spirometry is the most common pulmonary function test used in asthma diagnosing. However, it requires good patient co-operation. FOT has gained increasing attention for the measurement of pulmonary function in children because...
