Catheter Types, Sites and Techniques

CVP (aka Right atrial pressure)

provides info on pt's cardiac preload aka venous return

and intravascular volume

PICCS

end at SVC but placed through basilica or cephalic veins of arms

Power port PICCs (without valves) have normal CVPs to CVCs. Otherwise PICC CVP are 1 (3/-3) mmHG higher than CVC.

Waveform Analysis

Measure Mean CVP

A WAVES: Highest point-lowest point/2

V WAVES: (pt has a flutter or AF) highest point-lowest point/2
