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