Scenarios
A patient is SOB, has RR 28 , JV distension, + 2 pitting edema, CVP 10 mmHg and Pulmonary Wedge Pressure 8 mmHg Based on these results you should recommend that the patient be treated for:
Fluid overload
What is the name for the amount of blood pumped out of the heart with each beat?
Stroke volume
What refers to the stretch of the heart's ventricles at the end of diastole (when the heart is filling), which is determined by the volume of blood in the ventricles at that time
Pread-load
CVP 1 mmHg PAP (9 mm Hg) PCWP 3 mmHg Which of the following is the patients most likely diagnosis?
a. Congestive heart failure
b. Hypovolemia
c. Cor pulmonale
d. Pulmonary hypertension
Hypovolemia
What is the name for the amount of blood pumped out of the heart with each minute
Cardiac Output
What is is the pressure the heart must work against to eject blood during systole.
Afterload
A pulmonary artery catheter shows the following measurements. CVP 6 mmHg PAP 40/20 mmHg (27) MAP 100
mmHg. A coworker asks you for the source of the patient’s problem. The correct response is that the patient has a problem with his:
a. Pre-load
b. After-load
c. Contractility
d. Chronotropic control
After-load
What are the three components of stroke volume?
preload, afterload, and contractabillity
What is the ability of muscle cells to shorten and generate force.
Contractility
The patient CVP is low. What do you recommend?
Administer fluids.
Which parameter is more reliable to measure cardiac output without invasive hemodynamics
MAP
What is the name of the byproduct of cellular metabolism that accumulates when the body doesn't have enough oxygen.
Lactate
The patient wedge pressure is low what you recommend?
Fluids
Where is the pulmonary catheter position?
In the pulmonary artery
This measure measure the saturation of oxygen carried in your red blood cells
Pulse oximetry
