Does Emphysema Affect COPD Patient Compliance with Use of a Noninvasive Mechanical Ventilation Device ?

Methods: A cross-sectional, observational study was conducted from the outpatient clinic with COPD patients with and without emphysema who had presented at the respiratory intensive care unit between 2014 and 2018 with chronic respiratory failure and who had a thorax computed tomography image recorded within the past year and were using a domiciliary NIMV device. Data regarding demographic information, comorbidities, NIMV mode and duration of use, pulmonary function test, arterial blood gas, whole blood count, C-reactive protein level, and complications were documented from outpatient clinic records and the 2 groups were compared.
