Answer 2

breaths/min / title volume

Question 3

criteria for extubation

Answer 3

inspiratory pressure <-25
TV >5
VC >10
Min vent <10
RSBI <100

Question 4

what does milrinone do to pulm vasc resistance?

Answer 4

decrease

also increases cardiac output
phosphodiesterase inhibitor

Question 5

does dobutamine increase or decrease SVR?

Answer 5

decrease

increases cardiac output

Question 6

What happens to the diaphram in abdominal compartment syndrome?

Answer 6

the diaphram elevates due to increasing pressures -> decreased flow to IVC -> decreased cardiac preload
