Using dynamics of forced expiration to identify COPD where conventional criteria for the FEV 1 / FVC ratio do not match

Detailed mathematical analysis of expiratory flow dynamics in combination with support vector machine is able to detect airflow limitation and characterize presence of COPD. This methodology allows better identification of subjects with or without COPD characteristics when other spirometry‐based cri...

Summary:Detailed mathematical analysis of expiratory flow dynamics in combination with support vector machine is able to detect airflow limitation and characterize presence of COPD. This methodology allows better identification of subjects with or without COPD characteristics when other spirometry‐based criteria and specific cut‐offs do not confirm COPD.
