Cvicu Test Study Guide 2023 Graded A

SVO2 Normal {Ans: } >60%Low SVO2 {Ans: } Inadequate oxygen delivery or increased oxygen consumption Ex: fever, pain, bleeding, infectionHigh SVO2 {Ans: } increase in CO, decrease in oxygen demand, reduction in oxygen extraction Ex: anesthesia, hypothermiaCVP Normal {Ans: } 2-6High CVP {Ans: } over hydration, cardiac tamponade, heart failure, pulmonary stenosis. Patient needs diuresis, vasodilation, or treatment for tamponade.Low CVP {Ans: } hypovolemic shock for hemorrhage, fluid shift, dehydration. Patient needs fluid.Normal SVR {Ans: } 800-1200High SVR {Ans: } vasoconstricted ex: hypothermia, hypovolemia, medsLow SVR {Ans: } Meds, sepsis, re-warming, hyperthermiaNormal PAP {Ans: } 25/10PAP waveform {Ans: } Pulled back t0o far: ventricular waveform Pulled in too far: Wedge waveformRed port on the Swan {Ans: } balloon for a wedge pressure if orderedYellow port on the Swan {Ans: } Measures PAP Can only use this to draw a mixed venousBlue port on the Swan {Ans: } Measures CVP Can push meds through thisWhite port on the Swan {Ans: } CO/CI and temperature other white port it for fluidsWhen do you zero the Swan? {Ans: } q-shift and when you open the system. zero at phlebostatic axisNormal wedge pressure {Ans: } 8-12 High wedge: LV failure and tamponade Low wedge:
