Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. It's typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.

The best test for COPD is a lung function test called spirometry. This involves blowing out as hard as possible into a small machine that tests air movement and lung capacity. The results can be checked right away.

DIHPL have COPD-trained physician and nursing staff as well as specialized equipment, such asinhalers, PEP devices, nebulizers, portable oxygen machines, and CPAP and BiPAP machines which is used to treat COPD.
