29
What is COPD
Is a long standing airway obstruction, caused by Bronchitis, Asthma and Emphysema. this condition may be present alone or in combination .
30
COPD is characterized by:
- Dyspnea at rest or Exertion | - Productive cough
31
Emphysema
Means air trapping + Caused primarily by cigarette Smoking + As the disease advances more and more alveolar wall are destroyed
32
The main Symptom of Emphysema is?
Breathlessness , either at rest or with exertion.
33
In advanced Emphysema, what contribute to Dyspnea?
Hypoxemia
34
On Emphysema DLCo will be
Reduced
35
On Emphysema Chest X-Ray will show
+ Flatted Diaphragms and increased air spaces + The lungs appears hyperlucent (Dark) + Heart appears to be hanging from the great vessels
36
What Enzyme deficiency causes the gradual destruction of the alveolar wall?
Alpha1 -antitrypsin
37
On Emphysema FEV1 will be?
Reduced
38
It is present when there is excessive mucus production, with a productive cough on most days, for at least 3 months for 2 years or more.
Chronic Bronchitis
39
Chronic Bronchitis main cause
Smoking Cigarettes, also exposure to environmental pollutants
40
What test may be used to distinguishing between Emphysema and Chronic Bronchitis
DLCo, Chronic Bronchitis patients may have preserved DLCo, while Emphysema patients DLCo is reduced
41
Bronchiectasis is:
Is the pathologic dilation of the bronchi
42
The main feature of Bronchiectasis is:
Very productive Cough, the sputum is usually purulent and foul smelling.
43
Treatment of Bronchiectasis?
Bronchial Hygiene Antibiotic Therapy Bronchoscopy and surgical resection
44
The most common presentation of Asthma include:
Wheezing cough shortness of breath
45
Disease that primarily affects the mucus production apparatus of the lung and pancreas?
Cystic Fibrosis
46
Clinical manifestation of CF include:
+ Chronic Cough and Sinusitis + Bronchiectasis + Atelectasis
47
The primary management of CF is:
Removal of excess of mucus produced.
48
Symptom of Sarcoidosis include:
Fatigue, muscle weakness, fever and weight loss
49
What disease shows relatively normal flows on PFT?
Sarcoidosis
50

Sarcoidosis
51
``` + Under weight + Barrel-Chest + Use accessory muscles + Purse-lip breathing Is characteristic of what condition? ```
Emphysema
52

2 hours
54
Alcohol consumption should be refrain for:
4 hours before testing
