Q

ED –> acute asthma exacerbation –> refractory –> rescue therapy? why is this used?

A
  • racemic epi nebulizer
  • SQ epi

Q

sarcoidosis –> tx

18
Q

68F in ICU –> ventilated on positive pressure –> acutely becomes agitated –> oxy sat drop from 96% to 85%

what condition?

A

barotrauma from positive pressure ventilation

or

pneumothorax

19
Q

what is Cheyne-Stokes respiration

A

cycles of apnea followed by hyperpnea

20
Q

very deep breaths at fast rate

type of respiration pattern? seen in what condition?

A

Kussmaul

metabolic acidosis –> DKA

21
Q

patient initiate breath –> ventilator deliver breath –> backup rate in place if patient fail to initiate breath

what type of ventilation?

A

assist-control ventilation

22
Q

patient makes no respiratory effort –> what type of ventilation is appropriate for this patient?

A

controlled mechanical ventilation –> total ventilator dependent setting –> not allow or support spontaneous breaths

23
Q

diffuse parenchymal lung disease –> tx

24
Q

what are the idiopathic DPLDs? (2)

A
  • acute interstitial pneumonitis (acute <6wk)

- idiopathic pulmonary fibrosis (chronic >6mo)

25
what rheumatologic disorders can lead to pulmonary fibrosis? (3)
- SLE - RA - SS
26
sarcoidosis --> extra-pulmonary manifestations (3)
- heart block - bell's palsy - erythema nodosum
27
shipyard --> what occupational exposure?
asbestos
28
bird fancier --> what type of DPLD?
hypersensitivity pneumonitis
29
silicosis --> CXR findings can look like what other condition?
nodules in upper lung --> TB
30
ssx of DPLD at work --> feel better on weekend/vacation --> ssx come back when return to work what condition?
hypersensitivity pneumonitis
31
sarcoidosis --> diagnosed and treated --> what followup management?
cardiac MRI
32
sarcoidosis --> how dx?
lung bx
33
PE --> tx
- first line: factor Xa inh (rivaroxaban), if no renal dz | - LMWH --> bridge to warfarin
34
PE --> when trt w tPA?
R heart strain + hypotension
35
small cell lung CA --> tx
chemo + rad
36
squamous cell lung cancer --> paraneoplastic synd
PTH-rp --> hyperCa
37
PFT: differentiate emphysema vs chronic bronchitis
diffusion capacity of lung for carbon monoxide (DLCO): - emphysema: decreased - chronic bronchitis: increased
38
Lights criteria for exudate
- LDHf >2/3 ULN - LDHf/LDHs >0.6 - TPf/TPs >0.5
39
pleural effusion --> ADA positive dx?
TB
40
- erythema nodosum - hilar adenopathy - migratory polyarthralgia - fever what condition?
Lofgren's synd (sarcoidosis)
