Chest xray
Most ACCURATE test for COPD
Pulmonary Function Test
BEST DIAGNOSTIC test during ACUTE EXACERBATION
ABG
Target oxygen saturation for COPD
> 90%
MC risk factor for COPD
smoking
Primary pathophysiology of COPD
Airflow obstruction
COPD
Emphysema
Bronchitis
Small Airways Disease <2 mm
Risk Factors of COPD
Cigarette smoking
Airway hyperresponsiveness
Respiratory Infections
Ambient Air Pollution
Smoking exposure
Classic Symptoms of COPD
Dyspnea - progressive over time
Chronic cough
Chronic sputum production
Defined by the presence of COUGH and SPUTUM PRODUCTION for at least 3 mos in each of 2 consecutive years
Chronic Bronchitis
Normal value of Reid Index (COPD)
<0.40
3 MC symptoms of COPD
Cough
Sputum production
Exertional Dyspnea
Form of emphysema seen with CIGARETTE SMOKING (UPPER LOBE dominant)
Centrilobular emphysema
Form of emphysema seen in ALPHA 1 ANTITRYPSIN DEFICIENCY (LOWER LOBE dominant)
Panlobular emphysema
Form of emphysema associated with significant airway inflammation
Paraseptal emphysema
Major physiologic change in COPD
Airflow limitation
Major risk factor of COPD
Cigarette smoking
Major predictor of FEV1
Pack years of cigarette smoking
Risk of COPD mortality is closely associated with
Reduced FEV1
Independent poor prognostic factor in COPD
Wasting
Refers to the paradoxical movement of the rib cage
