ICU Hemodynamics Quiz

What is the primary goal of the ICU Advantage channel?

• To offer online medical degrees

• To entertain viewers with medical dramas

• To provide confidence in understanding ICU concepts

• To sell medical equipment

Which of the following is a directly measured hemodynamic value?

• Right atrial pressure

• Stroke volume

• Cardiac index

• Systemic vascular resistance

For a spontaneously breathing patient, what is the normal range for right atrial pressure?

• 8 to 12 mmHg

• 2 to 6 mmHg

• 0 to 8 mmHg

• 15 to 25 mmHg

How is stroke volume calculated?

• Heart rate times cardiac output divided by 1000

• Heart rate divided by cardiac output times 1000

• Cardiac output divided by heart rate times 1000

• Cardiac output times heart rate divided by 1000

What does stroke work represent?

• The volume of blood in the heart

• The amount of blood ejected per minute

• The resistance faced by the heart

• The force applied by the ventricle to eject blood

What is the normal range for left ventricle stroke work?

• 50 to 62

• 5 to 10

• 60 to 130

• 10 to 20

What does systemic vascular resistance (SVR) indicate?

• The preload of the heart

• The heart rate

• The afterload the left ventricle pumps against

• The contractility of the heart

How is pulmonary vascular resistance (PVR) calculated?

• 80 times the difference between mean pulmonary artery pressure and left ventricular end-diastolic pressure divided by cardiac output

• 80 times the difference between MAP and right atrial pressure divided by cardiac output

• Cardiac output divided by heart rate times 1000

• Heart rate divided by cardiac output times 1000

What is the normal range for pulmonary vascular resistance index (PVRI)?

• Less than 250

• 800 to 1200

• 1970 to 2390

• 255 to 285
