CVICU Test Questions and Verified Answers/Accurate Solutions| New Update
Already Graded A+
SVO2 Normal >60%
Low SVO2 Inadequate oxygen delivery or increased oxygen consumption
Ex: fever, pain, bleeding, infection
High SVO2 increase in CO, decrease in oxygen demand, reduction in oxygen extraction
Ex: anesthesia, hypothermia
CVP Normal 2-6
High CVP over hydration, cardiac tamponade, heart failure, pulmonary stenosis.
Patient needs diuresis, vasodilation, or treatment for tamponade.
Low CVP hypovolemic shock for hemorrhage, fluid shift, dehydration.
Patient needs fluid.
Normal SVR 800-1200
High SVR vasoconstricted
ex: hypothermia, hypovolemia, meds
Low SVR Meds, sepsis, re-warming, hyperthermia
Normal PAP 25/10
, PAP waveform Pulled back t0o far: ventricular waveform
Pulled in too far: Wedge waveform
Red port on the Swan balloon for a wedge pressure if ordered
Yellow port on the Swan Measures PAP
Can only use this to draw a mixed venous
Blue port on the Swan Measures CVP
Can push meds through this
White port on the Swan CO/CI and temperature
other white port it for fluids
When do you zero the Swan? q-shift and when you open the system.
zero at phlebostatic axis
Normal wedge pressure 8-12
High wedge: LV failure and tamponade
Low wedge: hypovolemia
Phase 1 monitoring Vitals q 15 min until aldrete >9
ABG 30 min after arrival
Where are epicardial wires located? Right side: A wires
Left side: V wires
