|
infection
|
|
cor pulmonale is ____ in bronchitis and ____ in emphysema?
|
rare, common
|
|
early stages of COPD
|
wheezing, diminshed breath sounds, reduced rib cage expansion, hyperresonance of lungs, coughing
|
|
advanced stage of COPD
|
pulmonary circulation, barrel chest, weight loss, hypercapnia
|
|
1st line of COPD therapy
|
anticholinergics
|
|
anticholinergics for COPD
|
via nebulizer or MDI
effectiveness for years do NOT use PRN slower onset than beta agonist |
|
2nd line of COPD therapy
|
beta agonist
use levalbuteral b/c it only has R isomer 1st choice for acute attacks |
|
3rd line of COPD therapy
|
Methylxanthines
|
|
leukotriene antagonist
|
block release of leukotrienes in lungs, counteracts inflammation
|
|
mast cell stabilizers
|
inhibit release of histamine to reduce allergic effects
|
|
theophylline/mexylxanthines
|
increase Camp to decrease release of histamine
|
|
corticosteroids
|
reduce inflammatory effect, reduce mucous secretions
|
|
step 1 mild intermittent asthma
|
treated prn
acute attacks treated with shortacting beta agonist needed <2x weekly nocturnal <2/mo |
|
step 2 mild persistent asthma
|
long term control
1st long term control dose w/ glucocort. and b2 agonist 2nd cromalyn and lk rec antagonist sx >2x/wk and >2x/mo. |
|
step 3 mild persistent asthma
|
1)inhale medium dose glucocort (leukotriene, theophylline)
2)low dose glucocort sx daily, nocturnal 1x/wk if pt is using short acting b2 agonist daily move step 4 |
|
step 4 severe persistent asthma
|
high dose inhaled glucocort w/ long acting b2 agonist. oral glucocort if needed.
|
|
green zone
|
no sx, PEF >80%
good control |
|
yellow zone
|
beta 2 agonist, if it doesnt work, use short course glucocorticoid
|
|
red zone
|
sx occur at rest or interfere w/ activities, PEFR is <50%
beta2 agonist inhaled immed. |
|
2 main asthma drug classes
|
antiinflammatory- cromolyn, glucocort
bronchodilators (beta agonist) |
|
glucocorticoids
|
NOT prn
most effective supress inflammation decrease release of inflammatory mediators, edema of airway mucosa increase b2 receptors |
