Answer 18

2.) Arterial filter

Question 19

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

Answer 19

Bad CPB

Question 20

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

Answer 20

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

Question 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?
