Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) are two of the most common pulmonary diseases. Unfortunately, they can also occur simultaneously in a phenomenon commonly referred to as Overlap Syndrome, creating twicefold the unpleasant conditions of disordered breathing.

This leads to long-term chronic health problems beyond the lungs (such as diabetes and heart disease) and their associated myriad complications.

The association between COPD as an obstructive lung disorder and OSA as a sleep breathing disorder means a person suffering from both has a compromised respiratory system that cannot even rely on sleeping at night for recovery or relief.
