Other Pulmonary Flashcards
signs on CT of pulmonary lymphangioleiomyomatosis?
diffuse thin walled cysts

SAH, PE, eclampsia, opiods naloxone, ASN, closed glottis, reexpansion
CT findings of cystic fibrosis?
upper lobe cylindrical bronchiectasis, tram tracking
CF pts at risk for what bug? tx?
pseudomonas/antipseudomonal B lactam and flq
CF with hemoptysis at risk for what?
colonization with S aueus or pseudomonas
High altitude pulmonary edema tx?
O2 and nifedipine reduce PAP
high altitude sickness and cerebral edema tx?
diamoxx and steroids
DLCO in DAH?
increased since blood in alveoli binds CO2 and prevents exhalation
NSIP presentation?
young female with subacute presentation
CT findings of NSIP?
b/l basilar GGO, temprally uniform, no honeycombing
BAL findings NSIP?
intraalveolar MO, and lymphocyte predominant
IPF difference from NSIP?
honeycombing without GGO, not temporally uniform
hypoxic events with normal Aa gradient?
hypoventilation, low PiO2
normal Aa gradient?
5-10 mmhg
mechanism of injury in drowning?
washes out surfactant and disrupts the alveolar membrane
PE findings of atelectasis?
dec tactile fremitus
CXR findings of atelectasis?
tracheal deviation to the atelectasis, elevated hemidiaphragm
Loeffler syndrome/hypersensiticity lung disease?
drug induced, cough rash fever eosinophilia, tx: steroids
Hypersensitivity pneumonitis mediation?
immunologic induced IgG mediation
CT findings of hypersensitivity pneumonitis?
centrilobular micronodules, GGO, mosaic pattern
central sleep apnea RF?
CVA hx, methadone, renal failure, hypothyroid, heart failure
symptoms of SVC syndrome?
HA with leaning forward, engorged veins over anterior chest, head and neck swelling
initial tx for SVC syndrome?
diuretics, elevation, O2
severe dz tx for SVC syndrome?
stenting with acute sx. Definitive tx is radiation
where are the plaques of asbestos?
parietal pleura
MOA of neurogenic pulmonary edema?
massive release of catecholamines, large capilalry leak
Radiation pneumonitis presentation?
latent period of 6 months- dry couhg, pleurisy, maybe fever
CT findings of radiation pneumonitis?
GGO that coalesce to form a sharply demarcated area, and GGO will cross the fiddure line
radiation pneumonitis tx?
steroids
3 things to diagnose berrilyiosis
exposure hx, positive blood or BAL lymphocyte test, non caseating granulomas
what constitutes a large BP fistula?
> 5mm, can do thoracostomy
diagnois of MTX pneumonitis?
restrictive PFT, dec DLCO, bx with marked eos, and smear with eos
Methemoglobinemia low Sao2?
dark pigment and machine gets confused for deoxyhemoglobin. So will have a ABG with high Pao2
dangerous levels of methemoglobin?
> 20% causes cyanosis, AMS, cardiac issues
blood of methemoglobin?
chocolate colored
centrilobular micronodules on imgaing?
hypersensitivity pneumonitis
MTX induced pneumonitis?
similar to hypersensitivity pneumonitis with dry cough, eosinophilia, negative cultures, GGO on CT
Restrictive pattern on PFT and decreased DLCO
underlying causes of DAH?
vasculitis, APS, renopulmonary syndromes
DAH post BMT tx?
corticosteroids

peri engraftment respiratory distress syndrome
hypersensitivity pneumonitis mediation?
IgG mediated respone to dust
CT scan of hypersensitivity pneumonitis?
centrilobular nodules, widespread GGO, mosaic pattern
clinical presentation of hypersensitivity pneumonitis?
sensitization and then repeated exposure to dust, think farmers
asbestos plaques are where?
parietal pleura, unlikely to become cancerous
POPE
post obstructive pulmonary edema- trach, laryngospasm
normal A-a gradient?
5-10 mmhg, increases with age
portopulmonary HTN findings?
will have pulmonary HTN and RV strain
difference between portopulmonary HTN and hepatopulmonary syndrome?
no orthodeoxia
meds used for the prevention of high altitude pulmonary edema?
dexamethasone if a a history of dz,
salmeterol
meds used to treat high altitude pulmonary edema?
CCB, nifedipine
meds to decrease risk of high altitude sickness, cerebral edema?
acetazolamide, dexamethasone
what level to obtain in anaphylaxis?
tryptase will remain elevated for longer, but hsitamine will initially be elevated
