NSG 3336 Lecture Notes - Lecture 26: Pulmonary Function Testing, Pulse Oximetry, Bronchial Hyperresponsiveness
Document Summary
Risk factors = family history, eczema, and presence of allergies. Pathophysiology = chronic lung disease characterized by an intermittent, reversible airway obstruction resulting from in ammation of the lung"s airways and a tightening of the muscles that surround the airways. Affects bronchial airways, not the alveoli > airway obstruction and bronchial hyperresponsiveness. Exposure to irritants triggers an in ammatory response > bronchospasms, mucous production, and edema. Clinical manifestations = wheezing, dyspnea, coughing, increased sputum, increased respiratory rate, chest tightness, tachycardia, increased anxiety, inability to lie at or speak in full sentences, and decreased peak ow readings. Classic sign of asthma attach is the inability to speak in full sentences. Diagnosis = detailed patient history, pulmonary function tests, chest x-ray, pulse oximetry, and abgs. Patient history > childhood illnesses, family history of allergies or asthma, smoking history, occupational history, and exposure to environmental triggers. Chest x-ray > rule out other respiratory conditions.
