Chronic Obstructive Pulmonary Disease, Smoker Lung
About this trial
This is an interventional other trial for Chronic Obstructive Pulmonary Disease focused on measuring elastography, ultrasound, copd, smoke, lung stiffness, lung ultrasound

Patients with COPD or fibrosis
Smokers with no signs of COPD
Healthy non-smoking volunteers
Subjects, enrolled on either an inpatient or outpatient basis, with stable COPD or fibrosis documented by anamnestic, imaging and functional tests. They will undergo lung function tests and bedside lung ultrasound integrated with lung elastosonography.
Subjects with an active smoking habit or a personal history of hard smoking dating back to maximum 5 years before, without clinical and functional signs of COPD. They will undergo lung function tests and bedside lung ultrasound integrated with lung elastosonography.
Healthy volunteers who have never smoked and who have no clinical or functional sign of COPD or other respiratory diseases. They will undergo lung function tests and bedside lung ultrasound integrated with lung elastosonography.
