What are the measurements?
What is the RAP measuring?
Right Atrial Pressure measures the pressure in the right atrium for the blood to be pushed to the arterial system.
What does SvO2 measure?
Mixed venous blood oxygen saturation measures the precent of oxygen that is being delivered to the patient is equitable.
What is thermodilution cardiac output method?
The solution with a known temperature is injected rapidly into the Proximal (CVP) port and the amount of time for the solution to mix with the surrounding blood is calculated, along with the pt's temperature and specific gravity to get the C.O value.
What is the normal value range of Cardiac Output (C.O)?
4-8.0L/min
What is the PAP measuring?
Pulmonary Artery Pressure measures the blood pressure in the pulmonary artery.
Normal SvO2 values?
mixed venous 60-80%
Central venous 60-70%
Describe or draw a normal thermodilution curve
A sharp upstroke with an elongated curve depending on cardiac output.
What is the normal value range of Cardiac Index (C.I.)?
2.5-4.5 L/min/m2
What is C.I. measuring?
Cardiac Index is the amount of blood that is able to be pumped based the patient's size.
Normal Value 2.5-4.0 L/min/m2
There are four key clinical factors that influence SvO2- what are they?
1. Cardiac Output
2. Hemoglobin
3. Arterial oxygen saturation
4. Oxygen consumption
When is the thermodilution injected?
End expiration
What is the normal value range of Storke Volume Resistance (SVR)?
Normal value 900-1400 dynes-sec/cm-5
What is C.O measuring?
Cardiac Output is the volume of blood the heart pumps in one minute.
Normal value 4.0-8.0 L/min
Decreased SvO2 means what?
Cardiac output is not high enough to meet the demands of oxygenation needs of the patient.
How many times do we complete the thermodilution for every cardiac output measurement?
on average 3
What is the normal value range of systolic and diastolic Pulmonary Artery Pressures?
normal value systolic 15-25mmHg & diastolic 8-15 mmHg
What is SVR measuring?
Systemic Vascular resistance is measuring the amount of resistance it takes to push the blood from the aorta to the right atrium (systemic circulation).
Continued drop in SvO2, what are some causes to trouble shoot?
Low Hgb
Oxygen consumption has increased without increased oxygen delivery
Prolonged injection push time
What is the normal value range of Normal Ejection Fracture for the Left and right side of the heart?
Left side normal EF 60-75%
Right side normal EF 45-50%
