COPD Flashcards
Structural abnormalities
narrowing or airways
enlargement of the air spaces distal to the terminal bronchioles with destruction of their walls- emphysema
expansion of the chest
Physiological abnormalities
reduces rate of airflow to air sacs
greatest reduction in airflow- expiration
Dynamic hyperinflation
Prior events
smoking, repeated chest infections, family history, exposure to dust in the workplace
Experienced symptoms
dyspnoea
wheeze
phlegm (clear normally, coloured when infected)
cough
signs
tachypnea hyper-inflated chest wheeze breath sounds decreased in intensity prolonged expiration
Abnormal test results
Chest X-ray- hyperinflated lungs
Reduced FEV1
Hypoxia
Hypercapnoea
Medical intervention
Antibiotics
Beta-2 receptor antagonists- bronchodilator therapy
antocholinergic bronchodilator therapy
long acting Beta-2 agonists - salmeterol
Inhaled sterois - budesonide
oral steroid (prednisolone) anti-inflammation therapy (for bad wheeze)
O2 therapy (low flow)
