Question 1

3 remedies for hemolysis in VV-ECMO

Answer 1

decrease pump speed; change circuit; increase anticoagulation

Question 2

4 remedies for chugging/chattering of VV-ECMO

Answer 2

decrease pump speed/flow; increase gas sweep (to decrease pt ventilatory effort); unkink tubes; volume resuscitation

Question 3

Do PFTs acquired from ILD pts while clinically stable correlate with severity in a given acute exacerbation?

Answer 3

no.

Question 4

In pressure control, if Vt increases when PEEP is lowered, what does this mean?

Answer 4

Alveoli were overdistended at higher PEEP

Question 5

Name the dyssynchrony.

Answer 5

flow dyssynchrony (note scalloping of pressure waveform)

Question 6

Name the dyssynchrony.

Answer 6

auto-triggering (trigger is too sensitive; here cardiac oscillations trigger the vent)

Question 7

Name the dyssynchrony.

Answer 7

double triggering

Question 8

What vent modes have constant flow?

Answer 8

VC and VA

Question 9

What vent modes have constant pressure?

Answer 9

PC and PS

Question 10

Name vent mode

Answer 10

VC
