1. Emphysema By Erin Brown

2. What is Emphysema? A type of Chronic obstructive pulmonary disease (COPD) Very progressive Alveoli and lungs are gradually destroyed. Lungs are unable to perform the gas exchange properly No cure One of the top 3 causes of death http://www.mayoclinic.com/health/medical/IM04560

3. Causes *Smoking ▫Tobacco ▫Marijuana ▫Most common cause Air pollution Manufacturing fumes/toxins ▫Coal dust ▫Silica dust Rare inherited protein deficiency

4. Physiology Tissue of the inner walls of these air sacs are weakened and holes appear. Elastic fibers of the airways to the alveolar sacs and lungs are destroyed. ▫Decrease of surface area of the tissue. Expirations takes place, the passages collapse. Oxygen is not able to enter the bloodstream.

5. Symptoms Inflammation of the alveoli Difficulty/highly forced exhaling Exhaustion Cyanosis ▫Blue coloring of the lips and skin Barrel chest Shortness of breath Pneumothorax ▫collapsed lung

6. Symptoms continued… High blood pressure Cor pulmonale ▫Section of the heart expands and weakens Increased heart rate Giant bullae holes in the lungs Frequent respiratory infections Persistent cough Hypoxemia ▫Lack of oxygen in the blood

7. Symptoms continued… Pulmonary hypertension Erythrocytosis Stroke Blood clots Lightheadedness Lung cancer Heart attack Difficulty concentrating Wheezing

8. Symptoms continued… Weight loss Swelling of the ankles Lung tissue scaring Bronchitis

9. Treatments Drugs & Surgery Lifestyle changes & Home Remedies Bronchodilators Inhaled steroids Corticoid steroids Antibiotics Pulmonary rehabilitation Supplemental oxygen Lung volume reduction Lung transplant *Stop smoking of any kind Stop using any drugs recreationally ▫Inhalants Avoid respiratory irritants ▫Pollution ▫Factory fumes Exercise Eat healthy foods, avoid unhealthy foods Protect yourself from the cold Avoid respiratory infections

10. Questions What are the early symptoms? What is the most common cause? Why is it amongst the top 3 causes of death? Where specifically does the disease start? Why would respiratory infections be common? Is a certain age group more likely to develop the disease?

11. Answers Early symptoms may include, coughing, shortness of breath, wheezing, exhaustion, frequent respiratory infections (bronchitis) etc. Smoking is the number 1 cause because of the large population of smokers. Also, because it has no cure and link to cancer and heart disease, it is amongst the top 3 causes of death. Specifically, emphysema starts in the alveolar sacs of lungs and spreads through out the lung tissue and air passage ways.

12. Answers continued Respiratory infections are common because the lung tissue and air passage ways are damaged. As a result, the lungs cannot adequately clean out the air. Also, the heart is affected in sending out blood with proper nutrients to the body and organs. Then, the organs are not able to function properly and the body weak and unable to fight off bacteria, viruses etc. No, not one certain age group is more likely to develop emphysema. Although, it may be more common amongst adults in their 30’s and up because of the time spent smoking damaging their lungs.
