The blood growth factor called granulocyte-colony stimulating factor G-CSF underlies airway inflammation and lung tissue destruction in COPDbut also the symptoms in other tissues, including the heart and bone, a new study shows. Follow-up studies strengthened this finding, offering evidence that high numbers of white blood cells in COPD are associated with damage to other tissues besides the lungs, including heart, muscles and bones. Specialized white blood cells, called neutrophils and macrophages, are key combatants in lung infections. In COPD, they promote a pro-inflammatory state and contribute to tissue destruction.

The EPA estimates that up to 24 million Americans -- primarily over the age of 45 -- suffer from chronic obstructive pulmonary disease COPD and many more are diagnosed with similar symptoms caused by emphysema.
Both conditions restrict airway passages and are aggravated by airborne contaminants, especially cigarette smoke and synthetic surfaces that create volatile organic compounds VOCs. Most residential air purifications units remove a portion of these irritants from the immediate environment, but their effectiveness is limited and determined by the features included in each model.
Both emphysema and chronic bronchitis sufferers experience: Shortness of breath, especially after engaging in physical activity A feeling of tightness in the chest Recurring respiratory infections A chronic cough or wheezing image courtesy of Wikipedia Commons These symptoms are no doubt affected by air qualityand studies by the EPA in ranked indoor air quality as a "high-priority public health risk," especially for persons suffering from such serious respiratory conditions.
Consequently, just having a top-of-the-line air purification system will not replace medically prescribed treatments such as inhalers, antibiotics and steroids that may be recommended to keep the disease from escalating. Do Doctors Recommend Air Purifiers? Most doctors do, however, highly recommend air purification equipment as part of a restorative regime for patients who have COPD or emphysemaand physicians can recommend the right type of system on a case-by-case basis.
Traditional HEPA filters only remove particles down to.
To effectively remove the majority of the irritants, patients with respiratory illness need to select a multi-stage filtration system. For ultimate protection, residential air purification systems portable or HVAC should contain several of the following: A pre-filter for removing large particles UV light exposure long enough to eliminate mold and mildew A membrane filter or a micro-filtration unit to capture pollutants down to.
Standard air filters for these units are limited by the small horsepower output of the fan motor, so a self-contained filteration system with its own fan will be more effective. HEPA-type filters are usually sufficient to filter most of the larger particles.
No Air Purifier is a Complete Solution Medical professionals always point out that no air purification system can be expected to eliminate all airborne contaminants, especially those stirred up by walking across a carpet or laying on a pillow since they must enter the airstream of the unit before they are filtered out.
They strongly recommend that steps should be taken to remove items that generate dust and eliminate any mold or mildew at the source. Frequent vacuuming and dusting of surfaces is highly recommended.

Chronic obstructive pulmonary disease (COPD) affects 6% of the general population and is the fourth-leading cause of death in the United States with severe and very severe disease accounting for 15% and 3% of physician diagnoses of COPD.
