Question 1

stress index helps determine _____ setting on the vent

Answer 1

PEEP

Question 2

Stress index looks at the _____ curve on the vent.

Answer 2

slope of the airway pressure

Question 3

What indicates low PEEP using stress index?

Answer 3

decreasing slope (of airway pressure curve)

Question 4

What indicates high PEEP using stress index?

Answer 4

increasing slope (of airway pressure curve)

Question 5

Why does decreasing slope of pressure curve indicate low PEEP?

Answer 5

alveolar recruitment

Question 6

Why does increasing slope of pressure curve indicate high PEEP?

Answer 6

overdistention of alveoli

Question 7

Next most likely Dx for ring-enhancing lesions on head CT for pt from tropical country if not cysticercosis, malignancy, or septic emboli/abscess

Answer 7

intracranial tuberculoma

Question 8

What developed between the two tracings in PRESSURE CONTROL mode?

Answer 8

circuit leak

Question 9

Advantage of PC over VC in ARDS pt w/ double stacking

Answer 9

Increases Vt less than in double stacked breath (and relieves the asynchrony)
