Chronic Obstructive Pulmonary Disease & Emphysema

Chronic obstructive pulmonary disease (COPD) encompasses several diffuse pulmonary diseases including chronic bronchitis, asthma, cystic fibrosis, bronchiectasis, and emphysema. The term usually refers to a mixture of chronic bronchitis and emphysema.

Bronchiectasis

Review of Colds

Allergic rhinitis symptoms (runny nose, mild congestion, itchy eyes) seem to be associated with the move to a new location. Headache may be due to congestion. Wheezing may indicate new onset of asthma.

Assessment of Colds

Dress normally, maintain clear fluids and healthy diet, and rest as much as possible. Wash your hands frequently, and clean surfaces with antiviral products, such as Lysol, to prevent spreading your cold to others.

Pulmonary Infections

Acute pneumonia is a potentially life-threatening illness requiring rapid diagnosis and treatment. A delay in antibiotic treatment increases the risk of a fatal outcome. Annually, 2 to 3 million cases of pneumonia are reported in the United States.
