Flashcards in Intro and cough Deck (26):
1

3 timeframes of cough

acute 8wks

2

2 function of cough

1. clear mucous
2. protect airway from inhalation

3

what is pathway of cough

cough receptors>vagus>cough center (medulla)>vagus,phrenic, spinal motor> to cause caugh

4

3 phases of breathing

1. inspiratory
2. compressive
3. expulsive

5

3 causes of 90% of cough

1. upper airway syndrome
2. asthma
3. GERD

6

mech of upper airway syndrome

nasal drips into the back hit the cough receptors
- allergic rhinitis, sinustits, vasomotor

7

Tx of upper airway

1. antihistamines - not long term
2. nasal steroids or ipatropium bromide (vasomotor rhinitis)

8

diagnosis of asthma

- family Hx of atopy or asthma
- need spriometry

9

mech of GERD

regurg hits the cough receptors in the stomach

10

diagnosis of GERD (2)

1. 24hr monitoring - not used
2. treat with PPI and see if it gets better

11

7 other causes of cough

1. infection
2. ACEi
3. chronic bronchitis
4. bonchiectasis
5. CA
6. interstitial lung disease
7. recurrent aspiration

12

what is mech in resp infection

- mostly viral
- can lead to sectretions dripping back

13

Tx of RTI

may help to give ipatropium bromide
- not ABs

14

2 bacterial infections to worry about

1. bortadella pertussis
2. TB

15

what is pertusus

- whooping cough
- inspriatory stridor with cough
- can last months

16

Dx of pertusis

- nasopharyngeal swab
- highest sens. within first few weeks - often too late

17

Tx of pertussis

- only within first few weeks
- macrolide AB

18

mech of ACE cough

block breakdown of bradykinin - stimulate cough receptors

19

what is risk and Dx of chronic bronchitis

- smokers
- PFT

20

what is mech of bronchiectasis

inflammation>small airway damage> airway dilatation and scarring> chronic recurrent infections

21

6 general causes of bronchiectasis

1. post-infectious
2. primary immune
3. CF
4. alpha-1 anti-trypsis def.
5. inflammatory disorders (autoimmune)
6. airway obstuctions

22

what is on imaging of bronchiectasis

dilated thinkened airways

23

Tx of bronciectasis

treat with ABs to prevent worsening
- can do surgery if the area is small

24

what is cough from intestitial lung disease

persistent and non-productive

25

what is recurrent aspiration

- may be diff. swallowing
- ask if related to eating or drinking

26

3 red flags

1. hemoptysis
2. weight loss
3. abnormal CXR
