Hemodynamics exam 1 Questions and Answers Already Passed Latest Update 2025-2026
Contraindications for an IABP - Answers Severe aortic insufficiency
Aortic aneurism
Aortic dissection
Limb Ischemia
Thromboembolism
Positioning for IABP - Answers The end of the balloon should be just distal to the take off of the
left subclavian artery. Confirm by fluroscopy or cxr.
What is an IABP? - Answers Inner aortic balloon pump. Decreases afterload, takes work load off
of the heart. Helps heart/augments pressure. Forces the blood into clogged arteries and is filled
up with Helium gas.
What should the continuous pressure/drip rate be for Arterial lines? - Answers 3cc / HR or 300
mmHg (3cc/hr continuous flush)
Replace central line every ____ days? - Answers 7 - Use a J-wire to replace.
How many days can you use a central line before having to relocate to a new site? - Answers 14
days- infection can happen if not relocated.
Calculation for MAP - Answers Systolic + Diastolic + Diastolic/3
Dicrotic Notch - Answers The small notch on the downstroke on waveform, shows the closing
of valves (depending on where you are in the heart)
Normal cardiac output - Answers 4-8 lpm (5)
Cardiac index - Answers Cardiac output divided by 2 5/2=2.5..<----nl cardiac index
Auto Peep - Answers Should always be zero.. PEEP effects the right side of the heart.
SVR - Answers 80 x (MAP-CVP) /CO
Zone 1 - Answers (least gravity dependant area.) blood is prevented from flowing through this
region. alveolar dead space
CO= SV x HR - Answers cardiac output equation
Zone 2 - Answers Pumonary capillaries are perfused. alveolar pressure greater than venous
pressure. Blood flow progressively increases.
, Zone 3 - Answers Both the arterial and venous pressure are greater than alveolar pressure,
therefore blood flow through this region is constant. Arterial and venous pressure both increase
equally downward in this zone, and is the same throughout the entire zone.
Normal consumption of 02 in the body is? - Answers 250cc/minute
Normal Heartrates - Answers Newborns 70-170
child 90-120
adults 60-100
What port is the proximal port that terminates at 30 cm from tip of catheter? - Answers the
white port
4 Ports - Answers ...
CVP - Answers Measures veinous pressure
Art line - Answers Measures arterial pressure
Swan-Ganz Catheter - Answers Measures pulmonary artery pressure
What is the mean pulmonary artery range? - Answers 25/8, 14 mmHg
Hemodynamic measurements for a COPD patient or a pt with pulmonary hypertension? -
Answers Dramatically increases PAP
If the CVP and the PAP is increased and the PCWP is nl or decreased, what could be the prob?
What part of the body is causing the problem? - Answers A respiratory problem,, The lungs
At what part of the cycle should all pressures be taken? - Answers ...
Normal value= SVR - Answers 800-1500 Dynes x sec x cm -5
Normal Value= PVR - Answers 20-120 dynes x sec x cm -5
Normal Value= CI (cardiac index) - Answers 2.5
Normal Value= PAP - Answers 9-18 mmHg
Normal value= PCWP - Answers 4-12 cmH20
What will cause the CVP to increase? Why? - Answers Cvp(right heart cam) right heart failure,
Cor pulmonale, Lung disorders, Pulmonary embolism, Pulmonary hypertension, Hypervolemia.
Where is the CVP measured and what part of the heart or body does it monitor? - Answers
Measured in the SVC and it monitors the Right Heart.
