Flashcards in Bronchiectasis Deck (10):
1

What is the definition of bronchiectasis?

a dilation of the bronchi and bronchioles, which is chronic in nature and results in inflammation and damage to the walls of these airways

2

What are the causes of bronchiectasis?

chronic respiratory infections, tuberculosis lesions, secondary to patients with cystic fibrosis, bronchial obstruction

3

What is the pathophysiology of bronchiectasis?

-chronic dilation resulting from destructive changes caused by inflammation infection and in some cases, congenital defects
-damage to the cilia along with dilation of the airway hinders mucociliary transport causing secretions to pool

4

What are the clinical signs and symptoms associated with bronchiectasis?

-productive cough with large amounts of thick, purulent secretions, which may be foul smelling
-hemoptysis
-vital sign changes, typically what to expect from infection and hypoxemia
-blood gas changes
-other manifestations resulting from chronic hypoxemia

5

How do blood gases change with bronchiectasis?

-respiratory alkalosis with hypoxemia (acute alveolar hyperventilation caused by hypoxemia)
-in severe cases: respiratory acidosis with hypoxemia (chronic alveolar hyperventilation caused by hypoxemia)

6

What other bronchiectasis manifestations result from chronic hypoxemia?

-pulmonary hypertension causing cor pulmonale
-digital clubbing
-cyanosis

7

What characteristics of bronchiectasis show up on a chest xray or CAT scan?

-chest xray may show cystic spaces resulting from the cystic form of bronchiectasis
-high resolution CT scanning
-characteristics of pulmonary function studies

8

What are the characteristics of pulmonary function studies that show up on a chest xray?

decrease airflows and decrease in vital capacity

9

What is the treatment for bronchiectasis?

-pulmonary hygiene
-aerosol therapy
-bronchodilator therapy
-mucolytics
-antibiotics
-oxygen therapy
-routine vaccinations
-pulmonary rehab, home care

10

What are the different types of pulmonary hygiene?

-chest physical therapy
-ABI vest
-pep therapy
-flutter valve
