LA pulm 3 Flashcards
FB aspiration, pleural effusion, pneumothorax, pulm HTN, ARDS, sleep apnea
what differentiates costochondritis from Tietze syndrome
Tietze syndrome has the presence of palpable edema
most common foreign body aspirated in children
peanuts
what is mean age for FB aspiration and why
2 years, no molars
complications include bronchiectasis, pneumonia, lung abscess, atelectasis
FB aspiration
definitive dx test for FB aspiration
rigid bronchoscopy, therapeutic as well sometimes
what is the parapneumonic type of pleural effusion
non infected pleural effusion, secondary to bacterial pneumonia
what is the empyema type of pleural effusion
direct infection of pleural space, purulent
what is the hemothorax type of pleural effusion
gross blood; trauma or malignancy
what is the chylothorax type of pleural effusion
increased lymph, persistent turbidity after centrifuge
most common type of pleural effusion
transudative; CHF most common
nephrotic syndrom, cirrohosis, atelectasis, hypoalbuminemia
think transudative pleural effusion due to increased hydrostatic pressure or decreased oncotic pressure
Pulmonary emboli and malignancy in pleural effusion
usually exudative
percussion, fremitus, breath sounds in a pleural effusion
all decreased, dullness
blunting of costophrenic angles/meniscus sign
CXR in pleural effusion
best film for pleural effusion
lateral decubitus
gold standard for pleural effusion from thoracentesis
lights criteria
1. pleural fluid protein : serum protein > 0.5 or
2. pleural fluid LDH : serum LDH >0.6 or
3. pleural fluid LDH >2/3 the upper limit of normal LDH
primary vs secondary pneumothorax
primary is idiopathic
secondary is underlying lung disease
percussion, fremitus, breath sounds in a pneumothorax
hyperresonance, decreased fremitus/breath sounds
what type of CXR(position)
expiratory upright view
companion lines
visceral pleural line running parallel with ribs; pneumothorax
pulm HTN is what pressure
elevated mean pulmonary arterial pressure >20
BMPR2 gene defect
primary pulm htn
