Clinical Perfusion Exam 1 Questions with
Complete Solutions
Systemic Vascular Resistance (SVR) - Correct Answers
✅[(MAP-CVP)/CO]*80
700-1600 dynes*sec/cm^5
Cardiac Index (CI) - Correct Answers ✅CI=CO/BSA
2.5-4.2 L/min/m^2
can compare flows across all patient sizes
Pulmonary Vascular Resistance (PVR) - Correct Answers
✅[(MPAP-PCWP)/CO]*80
20-130 dynes*sec/cm^5
Swan-Ganz Measured Parameters - Correct Answers
✅Pulmonary artery pressure (PAP)
Pulmonary capillary wedge pressure (PCWP)
Central venous pressure (CVP)
Cardiac output (CO)
Blood Temperature (BT)
Mixed venous saturation (SvO2)
Swan-Ganz derived parameters - Correct Answers
✅Cardiac index (CI)
Systemic vascular resistance (SVR)
Pulmonary vascular resistance (PVR)
, Clinical Perfusion Exam 1 Questions with
Complete Solutions
5 lead EKG - Correct Answers ✅RA, LA, LL, RL, 5th
intercostal space (V5)
Most often displayed lead in cardiac cases - Correct
Answers ✅Lead II - inferior wall of LV (right coronary), best P
waves
V lead - anterior/lateral wall of LV (left coronary)
NIBP - Correct Answers ✅not useful in cardiac surgery
not enough of a pulse pressure
Wheatstone Bridge - Correct Answers ✅variable resistor in
pressure transducer, distortion of diaphragm changes voltage
across the resistor, changes current going to monitor,
converted and displayed
ABP transducer position - Correct Answers ✅if higher than
zero, reads lower than actual
if lower than zero, reads higher than actual
ABP site of cannulation - Correct Answers ✅radial artery
most common
femoral artery if radial not good, need IABP, or complex
aortic root, temp used if radial weird
