airway obstruction with increased airway resistance of airflow to lung tissues
Chronic Obstructive Pulmonary Disease (COPD)
four causes of COPD
chronic bronchitis
bronchiectasis
emphysema
asthma
the three common signs and symptoms that meds will relieve in COPD
dyspnea
bronchoconstriction
mucus secretions
inflammatory disorder of the airway walls associated with airway obstruction
asthma
tiggers for asthma
stress
allergens
pollutants
s&s of asthma
bronchospasm, dyspnea, mucus secretions
wheezing, coughing, tightness in chest
chemical mediators that are released by mast cells
histamine and prostaglandins
bronchial inflammation and excessive mucus secretions lead to airway obstruction
chronic bronchitis
bronchodilators that mimic SNS and act on alpha or beta receptors
sympathomimetics
increases cAMP in lung tissue causing bronchodilation and restores circulation and increases airway patency (a sympathomimetic)
epinephrine
side effects of sympathomimetics
tremors, HTN, palpitations, tachycardia
monitor ___ before, during, and after treatment with sympathomimetics
heart rate
a selective beta-adrenergic that causes bronchodilation
albuterol
is albuterol used for rapid or maintenance use
rapid (rescue inhaler)
rapid onset, short duration
common side effects of albuterol (selective beta-adrenergics)
excitability, tremors, and tachycardia (will lessen with time/continued use)
