Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Spirometry- once consented, the researcher will approach the patient at the bedside to perform spirometry with a hand-held portable spirometer and measure the usual values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), forced expiratory ratio (FER), inspiratory capacity (IC) etc. This will first occur within 24 hours of admission and then daily until discharge, and again at a 4 week follow-up. Testing should take around 30mins each time.

Summary
Brief summary
A simple breathing test, called spirometry, provides valuable information in the diagnosis and assessment of many lung diseases, including chronic obstructive pulmonary disease (COPD). There is little knowledge regarding usefulness of this test during COPD exacerbations requiring hospitalisations, and so is rarely performed. The purpose of this study is to assess how useful it is to perform spirometry in this setting.
