Front 1

STAYING OFF THE VENT

Back 1

requires a balance between the imposed work of breathing and the ability of the patient to do that work

Front 2

airways tumors or clogged ven filters

Back 2

increase RAW

Front 3

factors to be considered when someone comes off the vent

Back 3

1) underlying process reveresed
2)hemodynamically stable
3)adequate cough
4)maintain the airway
5)adeqaute respiratory drive
6)

Front 4

alkalemia

Back 4

tends to depress the respiratory drive

Front 5

weaning parameters

Back 5

1) MV 4-6 liters
2)RR BETWEEN 8 and 30
3)tv >325 cc
4)NIF -20

Front 6

VC requirement for weaning

Back 6

1) VC at least 10-15 cc's

Front 7

Back 7

1) less than 60 mm Hg
2)FiO2 less than 50
3) PEEP less than 8

Front 8

checklist for extubation

Back 8

1)oxygenation

Front 9

typical weaning techniques

Back 9

1)A/C with increased breathing
2)SIMV decreasing rate
3)SIMV, decreased R, decreased PS
