Along with sleep apnea and interstitial lung disease, chronic lung disease also includes Chronic Obstructive Pulmonary Disease (COPD). The third most common cause of death in the US (behind heart disease and malignant neoplasms) and a significant financial drain on the US economy is COPD, which is the focus of this report. The other chronic lung condition will share many of the same concerns with regard to COPD surveillance.
