Standardisation of spirometry

TL;DR: This research presents a novel and scalable approach called “Standardation of LUNG FUNCTION TESTing” that combines “situational awareness” and “machine learning” to solve the challenge of integrating nanofiltration into the energy system.

A self-complete measure of health status for chronic airflow limitation. The St. George's Respiratory Questionnaire.

TL;DR: The St. George's Respiratory Questionnaire is a valid measure of impaired health in diseases of chronic airflow limitation that is repeatable and sensitive andMultivariate analysis demonstrated that SGRQ scores summed a number of areas of disease activity.

The St George's Respiratory Questionnaire.

TL;DR: The St George's Respiratory Questionnaire is a standardized self-completed questionnaire for measuring impaired health and perceived well-being in airways disease and the background and rationale for its development are discussed together with an analysis of its performance.

Relationship between exacerbation frequency and lung function decline in chronic obstructive pulmonary disease

TL;DR: It is suggested that the frequency of exacerbations contributes to long term decline in lung function of patients with moderate to severe COPD.
