Risk factors for COPD - ANSWER ✔✔- Smoking or smoke exposure
- Alpha-1 antitrypsin deficiency (AATD)
,- Occupational dusts and chemicals

Emphysema (pink puffer) - ANSWER ✔✔wheezing in lungs
pathophysiology of chronic bronchitis - ANSWER ✔✔-cough and
sputum production for at least 3 month in each of 2 consecutive years

diminishes
-pt more susceptible to respiratory infections
Emphysema background - ANSWER ✔✔-abnormal distention of air
spaces beyond the terminal bronchioles with destruction of the walls of
alveoli (shown with wheezing)
-mainly caused from smoking and infection
-can lead to hypoxemia
-can lead to increased pulmonary artery pressure and can cause right
sided heart failure

production
-cough

, -cor pulmonale (can be caused by the low o2 in the vessels from the
COPD. this causes strain from the pulmonary HTN on R V and cause
HF)
Diagnostic test/ Assessment COPD - ANSWER ✔✔-PFT
-spirometry

Medical management of COPD - ANSWER ✔✔-smoking cessation
-drug therapy
-provide o2 therapy/breathing exercises
-bronchodilators prior to meals
