COPD Flashcards
(35 cards)
What is COPD?
Preventable and treatable disease characterized by persistent respiratory symptoms and airflow limitation
What are the main environmental exposure for COPD?
Tobacco smoke and the intimation. Of tocix particles and gases from household or outside pollution
What are the rare genetic risk factors for CPOD?
Mutation in the SERPINA1 gene that leads to alpha 1 antitrypsin deficiency
What is the leading cause of death worldwide?
COPD
What is the most common risk factor of COPD?
Tobacco smoke
What is required to make the diagnosis?
Spirometry
What evaluation confirms COPD?
FEV1/FVC< 0.70
What are disorders that cause symptoms close to COPD?
Asthma, HF, broncheoctasis, TB, obliteration bronchitis, and diffuse panbroncholitis
What are the 4 pharmacological management parameters for COPD?
- Severity of airflow limitation
- Nature and magnitude of current symptoms
- Previous hx of moderate band severe exacerbations
- Presence and type of other diseases (multimorbidity)
What are the front line treatments for COPD?
Ipatropium short acting
Tiotropium long acting
Aclidinium bromide long acting
Umeclidinum long acting
Glycopyrrolate long acting
What are the PD of the front line COPD drugs?
Block muscadine cholinergic receptors in the bronchi and promotes bronchodilation
What are the adverse effects of the front line COPD drugs?
Dry mouth
Irritation of the pharynx
Headache
What are the main risk factors for COPD?
Tobacco smoke
Environmental exposure
Rare Genetic variants
Abnormal lung development
Accelerated lung aging
What do exacerbation and comorbities contribute to in COPD?
contributes to overall severity, morbidity and mortality.
What does airflow obstruction result from?
Small airway disease (obstructive bronchitis)
Lung tissue destruction (emphysema)
What is important to remember regarding inflammatory structural changes?
It increases with disease severity and persistent after smoking cessation through unknown mechanisms.
What does smoking during pregnancy increase risk of?
affects fetal lung growth and development in utero and possibly the priming of the immune system
what are the environmental risk factors for COPD?
Indoor burning of wood
Animal dung
Crop residues
Coal
What are the best estimates of prevalence of COPD?
presence of airflow limitation as demonstrated by pre and post bronchodilator spirometry rather than simply self-reported symptoms or clinician diagnosis data
What are the characteristics of COPD?
Dyspnea
Wheezing, chest tightness
Fatigue, activity limitation
Chronic cough and/or sputum production
Periods of increase symptoms (exacerbations)
What is the key symptoms of an exacerbations?
Increased dyspnea
Exacerbations are often associated with?
Local and systemic inflammation caused by infection, pollution, or other insult to the airways
What is the classification of COPD Gold 1?
Mild; FEV >/= 80% predicted
What is the classification of COPD Gold 2?
Moderate; 50% </= FEV < 80% predicted
