Describe the pathophysiology and clinical manifestations of asthma
When asthma occurs, bronchi and bronchioles respond to stimuli by contraction of smooth muscle (bronchoconstriction).The mucosa is inflamed and edematous, with an increased production of mucus. This results in a partially or totally obstructed airway. The initial symptoms the patient may experience include cough, dyspnea, and a tight feeling in the chest. Signs may include wheezing, increased respiratory rate, and labored breathing. Increased heart rate (tachycardia) and hypoxia may also be observed. Longer, prolonged episodes of asthma may result in respiratory alkalosis that can proceed to respiratory acidosis as well.
