Pathophysiology 1 Module 5
Bronchiectasis
Define bronchiectasis - ANSchronic irreversible dilation and distortion of bronchi that is caused
by great irritation and destruction of the bronchial wall cartilage, blood vessels, elastic tissue
and clean muscle components
What can bronchial wall destruction lead to? - ANSmucociliary clearance deficiencies that
results on copious quantities of bronchial secretions and blood main to tenacious foul smelling
sputum
Is bronchiectasis obstructive or restrictive? - ANSobstructive
Why is is so critical to clear mucous? - ANSkeeps lungs freed from any infections
How does spirometry appearance in sufferers with early level bronchiectasis? - ANSnormal
Which 2 anatomic alterations does bronchiectasis result in? - ANS1) hyperinflation of the distal
alveoli because of expiratory check-valve obstruction
2) Atelectasis, consolidation, and fibrosis on account of complete obstruction of the bronchi.
What do patients with bronchiectasis have? - ANSchronic airway infection, punctuated by using
acute exacerbations and followed by modern airflow obstruction
Diffuse bronchiectasis - ANSdevelops in patients with genetic, immunologic, or anatomic defects
that impacts the airlines.
As diffuse bronchiectasis progresses, inflammation spreads past the airlines to the lung
parenchyma, inflicting fibrosis.
Focal Bronchiectasis - ANSfocal bronchiectasis, occurs when a massive airway turns into
obstructed.
Which lobe is impacted extra in focal bronchiectasis? - ANSthe right middle lobe because its
bronchus is mall and angulated, and has lymph noses on near proximity.
Lymphadenopathy - ANSdue to mycobacterial infection now and again causes bronchia
obstruction and focal bronchiectasis
