Hemodynamic Monitoring Flashcards
Invasive
Why are arterial lines used?
For monitoring
- Hemodynamic instability
- Vasoactive Medications
- Frequent ABG analysis
Invasive
Why are Pulmonary Artery Catheters used:
- Hemodynamic Instability
- Monitor PAP
- Assess mixed venous oxygen SVO2
- Measure CO/CI
Invasive
Why are Central Venous Catheters used TO/FOR?
TO
- Measure right filling pressure
- Estimate fluid volume status
- Assess central venous oxygen ScV02
FOR
- Large volume or irritant infusions
- Transvenous pacemaker placement
What are the components of Invasive Hemodynamic Monitoring?
- Invasive catheter
- Noncompliant pressure tubing
- Transducer and stopcocks
- Flush system
- Bedside monitor
When does JVD occur?
when central venous pressure is elevated.
Measuring jugular venous distension provides an estimate of ?
intravascular volume
Serum lactate levels can provide information regarding?
end-organ perfusion.
the flow of blood through the body’s blood vessels to the major organs fed by the circulatory system
Why is end-organ perfusion important?
For maintenance = prevents irreversible organ injury and failure.
What is the most accurate invasive monitor?
Arterial pressure –> continuous analysis of arterial pressure
What catheter is used for Pulmonary artery monitoring?
a flow-directed catheter
Pulmonary artery pressure monitoring is used to measure what?
- ) pressures in the pulmonary artery
2. and the LEFT side of the heart.
Right atrial pressure monitoring aka?
as central venous pressure monitoring
Why is CVP used?
used to estimate central venous blood/fluid volume and RIGHT heart function.
Invasive
What allows zero referencing and balancing ?
Three-way stopcocks, when attached to the transducer
What is a 3-way stopcock?
Used for simultaneous and continuous infusion of two fluids to connect
