3- Disorders Of Rep Flashcards
Atelactasis physical diagnosis presentations
Percussion -dull (absent breathe sounds)
Trachea-toward
Tactile fremitus
Most common cancer causing death in men and woman
Broncogenic carcinoma
Surfactant synthesis begins as
28 weeks
Maximal surfactant by how many weeks
35 weeks
The reason for atelactasis in newborns without surfactant
Increased alveolar surface tention causes collapse
Are the neutrophils in RDS of newborns
No
In a child with RDS what are the consequences from PEEP
- retinopathy of prematurity ( retinolental fibroplasia)
- bronchopulmonary dysplasia- damage to tissue
- hypoxia causes necrotizing entercolitis-gangrenous-> perforate -peritonitis from bacteria
- intraventricular hemorrhage
Predisposing. Factors for intraventricular hemorrhage
Prematurity
Hypoxia
Breech
Other name for ards
Diffuse alveolar damage
Shock lung
Leaky capillary syndrome
Non cardiogenic pulmonary edema
Most common indirect cause of septic shock that leads to Shock lung
Ecoli heat stable endotoxins
In ARDS what does the membrane edema in alveoli contain
Fibrin
Dead cells
In ARDS injury to neutrophils releases what
Oxygen free radicals, proteases
Arachidonic acid metabolities
In ARDS injury to alveolar macrophages secretes what ?
Oxidants, proteases , and IL -8 **
In ARDS proliferator stage with extreme damage to type 2 pneumocytes leads to what
Late stage-Progressive interstitial fibrosis- restrictive lung disease seen bilaterally **
In ARDS how does the chest x-ray look
Normal
