What does Cardiac output measure?
Qt or CO measures output of the L ventricle to the systemic arterial circulation.
N Values=5 liters/min (4-8Lpm)
What does PCWP represent,the pulmonary venous drainage back to the L heart and is referred to and estimate what?
A)L atrial pressure
L atrial filling pressure
L side pre-load
L Ventricular filling pressure
L Ventricular end-diastolic pressure
PAP diastolic value (8 mmhg)can be used to estimate the PCWP(*mmhg) when balloon will not properly inflate and catheter cannnot be wedged
Relationship between the PCWP and some clinical problems?
Clinical Problem: PCWP
1)mitral valve stenois:increas
2)CHF= increase
3)L heart failure: increase
What is the comparison of Pcwp and Pap used for?
To differentiate between cardiac and non cardiac pulmonary edema.
A)Increased Pcwp and Increased Pap= cardiac or cardogenic heart.
B)N Pcwp and Increased Pap=
Non cardiac or non cardiac lungs.
1)Normal PCWP Valves?
2)N PAP Values?

3)CVP N Values?
1)8 mmhg (4-12)range
2)Systolic=25mmhg
Diastolic=8mmhg
Mean=14mmhg
3)2-6mmgh(4-12)cmh20)
Part2
Clinical Assessment of
Hemodynamics.
Pathology:
1)R heart Failure:
cvp=^increase,pap=N/Decrease,
pwcp=N/decrease,qt=N
2)Cor Pulmonale:
cvp=^increase,pap=N/decrease,
pwcp=N/decrease,qt=N
3)Lung Disorders:
PulmonaryEmbolism,
Pulmonary Hypertension,
Air embolism=cvp=Increase,
pap=^increase,pwcp=N/decrease,
qt=N
Cardiac Index:CI
Is cardiac output(QT) divided by the body surface area(BSA)in meters=squared(m2)
CI=QT/BSA
Normal Values= N adult range is:2.5-4.0/liters/min/m2
Cardiac Output Equations
1) fick equation:
QT=V02/C(a-v)02(10)

2)Stroke Volume Equation:
QT=heartrate x Stroke Volume

3)Thermal Dilution:
(cold saline injection)
