Flashcards in Pulmonary Infections Deck (17):
1

CAP protective mechanism

nasal turbinates, epiglottis, cough, mucin, cilia

2

CAP patient predisposing factors

viral URI, cold weather, elderly (swallowing), immunocomprimised/chronic disease, influenza, smoking, EtOH/sedatives

3

Pathogenesis of CAP

transmitted via aspiration (respiratory droplets)- inhalation. Can come from nasopharyngeal flora (bacterial forms), microdroplets from other people (most viruses/TB), dust particles (fungi, nocardia) and other environmental particles (water- LEGIONELLA)

4

Most common cause of CAP

S. pneumoniae (40%)

5

Types of atypical pneumonia

mycoplasma pneumoniae, chlamydia pneumoniae, legionella pneumophila

6

When is legionella pneumophila prevalent?

elderly, smokers, immunocomprimised (THIS IS WATER BORNE)

7

Which lung is most common to develop pneumonia?

RLL (and its due to mouth flora)

8

Legionella Pneumo symptoms

minimal sputum, headache, confusion, abdominal pain, n/v, diarrhea, LFTs (HAS A HIGH MORTALITY RATE)

9

Tx of Legionella Pneumo

azithro

10

Dx of Legionella Pneumo

urine antigen

11

CAP signs and symptoms

acute- develops in 24-48 hrs. Cough, Pleuritic chest pain, Rigor, SOB

12

CAP Cough

purulent vs nonpurulent, color of sputum, frequency

13

CAP Pleuritic chest pain

chest pain made worse during inspiration. Indicated inflammation of the pleura. May be a/ pleural effusion.

14

CAP Rigor

involunatary shaking, INDICATES BACTEREMIA

15

Rigor is common in which etiology of CAP?

S. pneumo, also seen in S. aureus pneumo

16

CAP SOB

worrisome symptom, RR >30, one of the indicators for severity and hospital admission. Caused by V/Q mismatch. Best assessed by O2 saturation and ABG

17

CAP physical findings

Bad prognostic findings: RR >30, BP 125, Temp 40
