At Heartland Pulmonary and Sleep Medicine, we diagnose and treat pulmonary and sleep disorders.   Pulmonology is the area of medicine that focuses on the respiratory tract.  This includes the lungs, bronchial tubes, throat, pharynx, and nose.  Sleep Medicine concentrates on interruptions in sleep patterns.  This can include snoring, sleep apnea, narcolepsy, insomnia, and other sleep disorders.
