IntroductionPrior studies assessing outcomes of lung transplants from cigarette-smoking donors found mixed results. Oscillometry, a non-invasive test of respiratory impedance, detects changes in lung function of smokers prior to diagnosis of COPD, an

BackgroundChronic lung allograft dysfunction (CLAD) is the major cause of death post-lung transplantation, with acute cellular rejection (ACR) being the biggest contributing risk factor. Although patients are routinely monitored with spirometry, FEV1

Rationale Spirometry and plethysmography are the gold standard pulmonary function tests (PFT) for diagnosis and management of lung disease. Due to the inaccessibility of plethysmography, spirometry is often used alone but this leads to missed or misd

Correlation of respiratory oscillometry with CT image analysis in a prospective cohort of idiopathic pulmonary fibrosis

Autor: Chung-Wai Chow, Jin Ma, Clodagh M Ryan, Shane Shapera, Zoltán Hantos, Matthew Binnie, Joyce K Y Wu, Lena Nguyen, Emily Leah Dehaas, Anastasiia Vasileva, Ehren Chang, Jady Liang, Qian Wen Huang, Antonio Cassano, Jolene Fisher, Micheal Chad McInnis

Publikováno v: BMJ Open Respiratory Research, Vol 9, Iss 1 (2022)

Background Markers of idiopathic pulmonary fibrosis (IPF) severity are based on measurements of forced vital capacity (FVC), diffusing capacity (DLCO) and CT. The pulmonary vessel volume (PVV) is a novel quantitative and independent prognostic struct
