17
Q

What are the mail purposes of CVCs?

A

Monitor CVP and ScvO2

Admin of drugs that may cause phlebitis or extravasation

18
Q

What are the main purposes of an arterial line (art line)?

A

Obtaining ABGs

Invasive blood pressure monitoring

19
Q

What are the main purposes in using a PAC line?

A

CVP
SVR

20
Q

CardioQ peaks and base meanings

A

Taller peaks = better contractility

Wider bases = better volume status

21
Q

What are the three types of hemodynamic shocks?

A

1 - pump (cardiogenic-heart)
2 - fluid (hypovolemic)
3 - tubing (distributive - vessels)

22
Q

A

Decreases CO

23
Q

What is the main clinical feature of hypovolemic shock?

A

Decreases CVP

24
