Abstract:
The purpose of this review is to summarise the existing knowledge of the relationship between exposure to en-vironmental tobacco smoke (ETS) and the development of chronic obstructive pulmonary disease (COPD). A possible causal relationship between ETS and COPD has long been suspected. Prenatal as well as postnatal ETS can reduce the lung function of the child permanently. Albeit the causality is multifactorial, new evidence has emerged since the Surgeon General's report from 2006 and suggests, that ETS is an independent and significant risk factor for developing COPD.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
