NSER 7410 MODULE 4 ACTUAL EXAM WITH COMPLETE SOLUTIONS
What are the indications for an Art Line
Hemodynamically unstable patients requiring continuous monitoring of blood pressure
Frequent sampling of blood for laboratory analysis. For example, when frequent arterial
blood gases are required for an acutely ill patient
What is an Art line and what does it monitor
A canula inserted into a major peripheral artery (Radial, Femoral), that provides continuous
monitoring of the MAP, SBP, DBP
ABP is related to cardiac output and is influenced by vascular tone
What is central venous monitoring, and what does a CVP tell you
A central venous catheter is inserted into the vena cava or in a central vein that is in close
proximity to the vena cava (e.g., jugular vein, subclavian vein), with the tip located in the
Right Atrium
The diastolic pressure is measured at the end of diastole when the ventricles are relaxed
CVP is a determinant of preload
What are the indications for central venous monitoring
, Hypovolemia (e.g. hemorrhage)
Hypervolemia (e.g. fluid overload secondary to heart failure)
Rapid fluid replacement where large bore IV is required
Administration of meds that must be given centrally (e.g., norepinephrine).
What is the normal, or recommended range for CVP
2-6mmHg
Describe the tubing in an Art Line
Regular IV tubing from the bag to the transducer
High pressure tubing from transducer to patient
Facilitates the continuous flush of 3mL/hour to keep line patent
Stop cocks and a reservoir that can facilitate the return of the "discard" blood after
sampling
What is an Art line transducer
Senses the pressure as blood flows past the tip of the cannula, and converts it into a digital
read out
Pressure is sensed via the column of fluid between the patient and the transducer
