Flashcards in Peds - Respiratory Deck (34):
1

Egophany
o normal findings
o consolidative findings

Normal E --> A
Consolidation E --> E

2

Age for relatively reliable PFTs

greater than 8 years

3

FEV1 - normal is at least what number?

At least 80%

4

What does hyper-resonance indicate?

air trapping

5

What do these stand for?
FVC
FEV1
TLC

Forced Vital Capacity
Forced Expiratory Volume in 1 sec
Total Lung Capacity

6

OBSTRUCTIVE pulmonary disease -

o FVC
o FEV1
o FEV1/FVC ratio
o TLC

FVC - decreased or normal
FEV1 - decreased
FEV1/FVC ratio - decreased
TLC - normal or increased

7

RESTRICTIVE pulmonary disease -

o FVC
o FEV1
o FEV1/FVC ratio
o TLC

FVC - decreased
FEV1 - decreased or normal
FEV1/FVC ratio - normal
TLC - decreased

8

These normal breath sounds are harsh and sound like air is being blown through a pipe.

Tracheal

9

These normal sounds are loud and high in pitch with a short pause between inspiration and expiration; expiratory sounds last longer than inspiratory sounds.

Bronchial

10

These normal breath sounds are softer than bronchial sounds, but have a tubular quality. The sounds are about equal during inspiration and expiration

Bronchovesicular

11

These normal breath sounds are soft, blowing, or rustling sounds; normally heard throughout most of the lung fields and heard throughout inspiration, continue without pause through expiration and then fade away.

Vesicular

12

Viral disease of the lower respiratory tract where inflammation causes obstruction of the small respiratory airways.

Bronchiolitis

"bronchitis in little people"

13

Bronchiolitis - typical age

less than 3 years

14

Bronchiolitis - typical pathogen

RSV (50%)

15

Bronchiolitis - signs and symptoms (4)

o URI symptoms lasting several days
o increasing respiratory distress
o moderate fever
o palpable liver and spleen (hyperinflated lungs)

16

Bronchiolitis - xray findings

hyperinflated lungs
may have scattered consolidation

17

Prevention of RSV in high-risk infants

Synagis monthly during RSV season

18

High-risk for Synagis purposes (2)

o chronic lung disease under age 2
o preemie

19

Remodeling in asthma (3)

o thickening of epithelial basement membrane
o indicates severe stage
o permanent change

20

Asthma - ominous signs (4)

o absent breath sounds
o pulsus paradoxus
o inability to maintain recumbancy
o cyanosis

21

Asthma - diagnostics
o bloodwork
o PFTs
o other

o slight WBC increase, eosinophilia
o PFTs --> obstructive findings vv FEV1
o no radiograph unless r/o

22

Asthma - indications for hospitalization (2)

peak flow less than 60 L/min AND
no improvement with inhaled therapy

23

Asthma - frequency of monitoring

every 2 - 4 weeks for at least 3 months - until control is acheived

more frequently if more severe

24

Asthma - when can therapy be stepped-down?

After 3 months of good control

return in 2 weeks for recheck

25

Pneumonia - percentage caused by virus

70-80 %

26

Community-acquired Pneumonia - ABT
o preschool
o school age

preschool -
1st - amoxicillin
2nd - amoxicillin/clavulanate or macrolide

school age -
1st - macrolide
2nd - amoxicillin, or amoxicillin/clavulanate

27

Community-acquired Pneumonia -
which organisms does amoxicillin target?

S. pneumoniae
H. influenzae

(most likely bacterial causes of pneumonia in children)

28

An autosomal recessive disorder characterized by recurrent bronchial infection, progressive obstructive pulmonary disease, and pancreatic insufficiency with intestinal malabsorption.

Cystic Fibrosis (CF)

29

CF - selected sypmtoms (3)

viscous meconium
steatorrhea
salt-tasting skin

30

CF -
gold standard

Gold standard = pilocarpine iontophoresis sweat test

31

CF - PFTs reveal obstructive or restrictive pattern?

PFTs --> obstructive pattern

32

CF - blood worm reveals:

hyponatremia
hypochloremia

33

CF - chest radiograph

cystic lesions
atelectasis

34
