University of Texas, Arlington NURS 3481 Jennifer Hoffman.
Asthma is caused airway hyperresponsiveness characterized by bronchoconstriction and airway edema in response to exposure of a variety of stimuli including allergins and irritants. In acute asthma, bronchial smooth muscle contract as a response to allergins or irritants which leads to a narrowing of the airway, thus limiting the airflow. Furthermore, inflammation activates goblet cells to secret mucuous, increasing airway edema and formation of mucus plugs which further increases narrowing of the airway. The inadequate exchange of O2 and CO2 result in V/Q mistmatch. Subjective findings include, dyspnea, cough, chest tightness/pressure, and patient’s statements of breathing difficulty. Objective findings include, wheezing upon expiration, central cyanosis, mental alteration, P02 values 80, PCO2 values 45, O2 sat 95%, tachycardia, and tachypnea.
