Techniques of assessing small airways dysfunction

William McNulty and Omar S. Usmani   Abstract The small airways are defined as those less than 2 mm in diameter. They are a major site of pathology in many lung diseases, not least chronic obstructive pulmonary disease (COPD) and asthma. The small airways are frequently involved early in the course of these diseases, with significant pathology […]

Reference equations for respiratory system resistance and reactance in adults

Nathan J.Brown, WeiXuan, Cheryl M.Salome, NorbertBerend, Michael L.Hunter, A.W. (Bill)Musk, Alan L.James, Gregory G.King Abstract   Aim To determine reference equations for respiratory system resistance and reactance in a large randomly selected sample from a general, predominantly Caucasian population. Methods A prospective respiratory health survey of the general population in Busselton, Western Australia, was conducted between 2005 and 2007. Subjects had measures of spirometry, and […]

Transient reference values for impulse oscillometry for children aged 3–18 years

Bożena Nowowiejska MD, Waldemar Tomalak PhD, Jakub Radliński PhD, Grzegorz Siergiejko MD, Wojciech Latawiec PhD, Maciej Kaczmarski MD, PhD   Abstract Impulse oscillometry (IOS) is a technique of assessing mechanical properties of respiratory system by means of measuring resistances and reactances in a number of frequencies during tidal breathing. It is especially useful in preschool children, however has […]
