Cutting edge technologies in respiratory research: Lung function testing

摘要: Pulmonary function testing is part of routine clinical practice in respiratory medicine. It based around spirometry, which will remain the central measurement lung given its prognostic significance and integral role defining severity airways disease. However, there an increasing body evidence from studies using new methods are providing insights into pathophysiology This data forming a basis for their future role, once economics producing relevant devices becomes attractive. The forced oscillation technique multiple breath nitrogen washout currently most commonly used newer techniques, refinements long-established techniques. Optical coherence tomography, optical reflection, electrical impedance vibration response imaging have arisen by development novel devices. recent use these techniques reviewed.
