1

To determine what components are necessary to fully support the patient during surgery, what information is necessary?

* Surgery planned
* Height
* Weight
* Hematocrit

2

When selecting components for an extracorporeal circuit, the perfusionist must balance what 3 things?

1.) Reduction of prime volume
2.) Reduction of surface area
3.) The predicted need to accommodate maximal flow.

3

A circuit larger than needed causes what ?

Unnecessary hemodilution and increased blood to surface contact.

4

A smaller than needed circuit causes what ?

1.) Not enough oxygenation provided.
2.) Unacceptable high circuit pressures.

17

The #1 greatest resistance to flow from the arterial side of the circuit should always be what?

1.) the arterial cannula

18

The #2 greatest resistance to flow from the arterial side of the circuit should be what?

2.) Arterial filter

19

A venous reservoir "rated" to less than your top flow can compromise your venous return and result in what ?

Bad CPB

20

Venous reservoirs have a maximum flow rating, what does this mean?

Fastest rate at which blood can passively pass through its internal filter mechanisms.

21

An inappropriately sized arterial filter with top flow 2.5 L/m placed in an adult circuit and forced to filter 5 L/m can cause what problems?

1.) Unacceptably high resistance to flow.
2.) High line pressures
3.) Hemolysis
4.) Unnecessary hemodilution

22
