Introduction of topic: Lung involvement in vasculitis. |
00:28 |
Discussion of most common forms of vasculitis affecting the lungs: GPA, EGPA, and MPA; and least common: GCA, Takayasu arteritis, and PAN. |
01:14 |
Common symptoms in patients when lungs are affected. |
02:58 |
Potential causes of respiratory symptoms in vasculitis patients: active disease, damage, treatment complications, and other problems. |
04:55 |
What is dyspnea and what are the problems in different organs that can lead to shortness of breath? |
06:38 |
What are the most important parts of the respiratory system? |
08:47 |
Close-up view of air sacs (alveoli), a review of their purpose, and inflammation of the respiratory membrane. |
09:40 |
Diagnostic procedures to identify the cause(s) of respiratory symptoms in vasculitis patients. |
10:59 |
Chest imaging: views of chest x-ray and CT of the chest, along with discussion. |
13:25 |
Explanation of spirometry: function test to measure lung volume and flow; obstruction of main airways of bronchial tubes; how much of the oxygen can cross from the air sacs to blood vessels. |
14:15 |
Explanation of bronchoscopy: going inside lungs to determine narrowing or area of inflammation. |
14:56 |
Diffuse alveolar hemorrhage and image of the heart: discussion relative to GPA, MPA, and EGPA. |
