Flashcards in Pneumothorax Deck (25):
1

Air leak in pneumothorax most commonly originates from

Within the lung

2

Primary idiopathic spontaneous pneumothorax usually results from

Ruptured subpleural blebs

3

Pneumothorax that occurs without trauma or underlying lung disease

Primary spontaneous pneumothorax

4

Familial cases of spontaneous pneumothorax have been associated with mutations in what gene

Folliculin gene (FCLN)

5

Patients with synthesis defects of what connective tissue are unusually prone to the development of pneumothorax

Collagen (e.g. Ehlers-Danlos and Marfan)

6

A pneumothorax arising as a complication of an underlying lung disorder but without trauma

Secondary pneumothorax

7

Incidence of pneumothorax is relatively high in infants with this type of pneumonia

Staphylococcal

8

Which drugs of abuse are associated with pneumothorax

1) Ecstasy (MDMA) 2) Crack cocaine 3) Marijuana

9

T/F High flow nasal cannula therapy may cause iatrogenic pneumothorax

T

10

What is catamenial pneumothorax

Pneumothorax related to menses, diaphragmatic defects, and pleural blebs

11

Bilateral pneumothorax has been reported in which conditions

1) Neonatal period 2) After lung transplantation 3) M. pneumoniae infection 4) Tuberculosis

12

Mechanisms of hypoxemia in pneumothorax

1) Alveolar hypoventilation 2) V/Q mismatch 3) Intrapulmonary shunt

13

Pleural pressure in simple pneumothorax

Atmospheric

14

% lung collapse in simple pneumothorax

30%

15

Pleural pressure in tension pneumothorax

Increasing positive pressure

16

T/F severity of pain in pneumothorax usually reflects extent of collapse

F

17

This radiographic view accentuates the contrast between lung markings and the clear area of the pneumothorax

Expiratory view

18

T/F When the lungs are stiff (e.g. cystic fibrosis or RDS) the unaffected lung collapses easily hence shifting of structures likely occurs

F

19

A small pneumothorax is defined as a collapse of how many percent

5

20

A small or moderate-sized pneumothorax may resolve spontaneously usually within what time period

1 week

21

T/F Administration of 100% O2 in pneumothorax may hasten spontaneous resolution

T

22

T/F Needle aspiration is as effective as tube thoracostomy in emergency management of primary spontaneous pneumothorax

T

23

Indications for chest tube drainage of pneumothorax

1) Recurrent 2) Secondary 3) Under tension 4) >5% collapse

24

T/F Pneumothorax complicating CF usually recurs

T

25

Preferred therapy for blebectomy, pleural stripping, pleural brushing, and instillation of sclerosing agents
