Q

salicylate poisoning timeline?

A

(1) <12 hr= respiratory alkalosis
(2) >12 hr= respiratory alkalosis w/ metabolic acidosis (gap)

so pH will look normalish, w/ decreased PCO2 (more decreased than expected w just metabolic acidosis) and decreased bicarb

whats the risk of doing it below?

A
T8- midclavicular 
T10- midaxillary 
T12- midscapular 
above- injure lung 
below- injure abdominal contents

Q

transplant patient + pneumonitis + owl’s eye

A

17
Q

whats the most effective anti-inflammatory treatment for asthma which can also decrease mucus production

A

glucocorticoids

18
Q

causes of decreased lung compliance (3)

A
  • Left Heart Failure
  • lack of surfactant
  • pulmonary fibrosis
19
Q

secondary bacterial pneumonia
occurs after?
most common culprits?

A
  • after infection with influenza A

- – S. penumo, S. Aureus, H INfluenzae can cause pneumonia

20
Q

lung abcess treatment

A

Clindamycin

21
Q

Cheynes Stokes breathing, what disease?

22
Q

when is airway pressure 0 and intrapleural pressure -5

23
Q

second hand smoke puts kiddos at risk for

A

low birth weight
sudden infant death syndrome
otitis media
asthma

24
Q

what activates eosinophils (ex: in asthma)

A

TH2 cells releasing IL5

25
both PE and high altitude show what blood chemistries?
hypoxemia | respiratory alkalosis
26
red thick capsule on mucimarine stain?
Cryptococcus Neoformans
27
patients with CF produce sweat with high concentrations of what?
Cl | and Na
28
why is it a bad idea to give people with COPD VERY high levels of O2
it can increase the V/Q mismatch increases in oxygen will cause vasodilation and shunt blood to alveolar dead space--- causing an increasein physiologic dead space
29
"honeycombing" in lungs
Idiopathic pulmonary fibrosis
30
what causes tracheal deviation towards the affected side?
lung collapse- ex-- main stem bronchus obstruction
31
how does aging affect the lung?
- decrease in chest wall compliance - increase in lung compliance - total increase in residual volume, decrease in FVC, and the total lung capacity stays the same
32
branching gram positive organisms
Nocardia
33
what does obesity do to lungs?
restrictive lung disease patterns you will notice a much lower ERV.. and therefore a lower FRC (ERV+RV) note that RV stays more or less the same FEV1, FVC, and TLC may also go down slightly
34
hemosedrin laden macrophages in lungs=
"heart failure cells"
