Atelectasis Flashcards
1
Q
What is atelectasis
A
structural collapse of part of the lung
2
Q
is the affected part functional
A
no
3
Q
what are the three types of atelectasis
A
obstructive/absorptive, compression, contraction
4
Q
Explain obstructive
A
a/w obstruction dt mucus plug etc. air is trapped and absorbed into capillaries = lung collapse
5
Q
Explain compression
A
pressure on the lungs ex: tumor
6
Q
explain contraction
A
usually associated with injury. Scar tissue forms and contracts the lung tissue causing it to collapse. it is the hardest to reverse
7
Q
Manifestations
A
decreased lung capacity decrease chest expansion on the collapsed side dyspnea tachypnea tachycardia
8
Q
Diagnosis
A
Px, Chest x-ray, CT, bronchoscopy
9
Q
Treatment
A
address the cause (tumor, mucus plug)
reduce constriction and reflate the collapsed lung
ambulare, deep breathing, coughing, body positions
administer oxygen
