About COPD Stage 2
Chronic obstructive pulmonary disease (COPD) is a progressive disease that typically increases in severity over time. COPD Stage 2 is an early stage in the disease’s progression. This stage is also called moderate COPD.
Lung Capacity in COPD Stage 2
A major sign that a person has COPD is the capacity of his or her lungs is decreased. Due to constant inflammation of the airways, COPD patients struggle to breathe properly. They have difficulty blowing out air with any force, and the overall volume of air they can hold in their lungs is diminished. The forced expiratory volume test (FEV1) is essentially the volume of air that can be blown out in the first second of exhaling. Another significant test is the forced vital capacity (FVC) test, which measures lung’s volume capacity. When measuring lung capacity, a common statistic is a combination of the two tests called the FEV1/FVC ratio. This number essentially represents the percentage that the lungs can breathe out of the quantity of air inhaled. A healthy person has a FEV1/FVC ratio of or around 80 percent. Thus the lower the FEV1/FVC ratio the more significant the disease.
COPD Stage 2 is categorized by a FEV1 test score that is greater than 50 percent but less than 80 percent and a FEV1/FVC ratio of less than 70 percent.
Symptoms of COPD Stage 2 are:
- Chronic coughing
- Sputum: coughing up mucus
- Dyspnea: breathing discomfort
- Shortness of breath
- Chest tightness
Treatment of COPD Stage 2
Patients that seek medical assistance from a physician are occasionally prescribed ashort-acting bronchodilator and a long-acting bronchodilator to help increase airflow to the lungs . Given the major damage done by smoking with COPD, a smoking cessation plan is always recommended. Likewise, it is also recommended to monitor environmental factors to keep dust, air pollution and other particles out of the lungs. Additionally, a pulmonary rehabilitation program may also be recommended.
