Q

What are the modifiable risk factors of COPD?

A
  • cigarette smoking, 2nd hand smoke

- exposure to dust fumes: coal, class, asbestos

2
Q

What are the non-modifiable risk factors?

A
  • possibly repeated childhood respiratory infections (damage to alveoli and impairs lung defences)
  • apha-1-antitrypsin deficiency ( a protein produced by the liver and found in the lungs,; normal prevent destruction o the lung tissue; can develop emphysema
3
Q

What genetic predisposition can occur toward developing COPD?

A

AAT (alpha-1-antitrypsin deficiency)

4
Q

What is COPD?

A
  • chronic respiratory disorder that restricts airflow
  • progressive airway obstruction caused by chronic bronchitis and emphysema
  • causes decreased SA for gas exchange
  • airways collapse due to loss of elasticity in the lungs
  • work of breathing requires more energy and greater use of accessory muscles
5
Q

What is the pathophysiology of bronchitis?

A
  • inflammed bronchi
  • increased mucus
  • increased work of breathing
6
Q

How does bronchitis present?

A

Presents as:
productive cough, SOBOE, wheezing, decreased exercise tolerance, increased fatigue, chronic hypoxemia, difficulty with exhalation caused by airway obstructed by deem and excessive mucus

7
Q

What is the pathophysiology of emphysema?

A
  • decreased alveoli due to breakdown of lung’s normal defences
  • lg air spaces (bull and blebs)
8
Q

What presents with emphasyma?

A

Presesnts as progressive dyspnea, SOB, tachypnea, tachycardia, cough (late in disease), barrel chest, tripod postion, accessory muscle use, underweight, fatigue, decreased ADLs

9
Q

What presents with emphasyma?

A

Presents as progressive dyspnea, SOB, tachypnea, tachycardia, cough (late in disease), barrel chest, tripod postion, accessory muscle use, underweight, fatigue, decreased ADLs

10
Q

What presents with emphysema?

A

Presents as progressive dyspnea, SOB, tachypnea, tachycardia, cough (late in disease), barrel chest, tripod postion, accessory muscle use, underweight, fatigue, decreased ADLs
