About Stage Three COPD
Chronic obstructive pulmonary disease (COPD) is a progressive disease that typically increases in severity over time. Stage Three COPD is a later stage in the disease’s progression. This stage is also called severe COPD.
Stage Three COPD Lung Capacities
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. When measuring lung capacity, a common measurement is a combination of the forced expiratory volume (FEV1) and forced vital capacity (FVC) tests called the FEV1/FVC ratio. 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 Three is categorized by a FEV1 test score that is greater than 30 percent but less than 50 percent and a FEV1/FVC ratio of less than 70 percent.
Stage Three COPD Symptoms:
- Chronic coughing
- Sputum: coughing up mucus
- Dyspnea: breathing discomfort
- Shortness of breath
- Chest tightness
- Unintended weight loss
- Frequent respiratory infections
Stage Three COPD Treatment
There is no cure for COPD Stage three, but the following treatments can help with managing the disease:
- Short-acting bronchodilator
- Long-acting bronchodilator
- Smoking cessation and monitoring environment to reduce airborne particles
- Pulmonary rehabilitation class
