Asthma + COPD Flashcards
Asthma
Chronic inflammatory disorder, responsive to tirggers
airway inflamamtion contributes to airway hyperresponsiveness, airflow limitation
Reversible
Cellular Response of Asthma
mast cell eosinophils neutrophils T lymphocytes macrophages epithelial cells
Presenting Symptoms
wheezing
cough worse at night
difficulty breathing
chest tightness
Asthma Dx
airflow obstruction is partially reversible on spirometry
increase of FEV1 greater than 200mL and greater than 12% from baseline measure after using short acting beta 2 agonist
Goal of therapy for asmtha
reduce impairment
require infrequent use of SABA (less than 2x/week)
maintain normal pulm fxn and activity levels
prevent–>exacerbations, er visits, loss of lung fxn
provide optimal pharacotherapy w/minimal effects
COPD onset
later in life
COPD etiology
cigarette smoke
COPD course
chronic, progressive (nonreversible)
Clinical Features of COPD
chronic cough/sputum, persistant worsening dyspnea
Inflammatory mediator for COPD
neutrophils
Inflammatory mediator for Asthma
eosinophils
Nonpharm tx of COPD
stop smoking avoid triggers (cold air, pollutants) filter air adjust ADL's diet
most common cause COPD exacerbation
infection and air pollution
Albuterol
Levabuterol
Pirbuterol
SABA
Ipatropium
Anticholinergic (short acting bronchodilator)
