How is cardiac output calculated?
a.Systolic pressure minus diastolic pressure
b.Heart rate divided by stroke volume
c.Stroke volume multiplied by blood pressure
d.Heart rate multiplied by stroke volume
Explicación
Cardiac output equals heart rate times stroke volume, the amount of blood ejected by the left ventricle each beat, and it is normally about 4 to 8 liters per minute in an adult. Subtracting diastolic from systolic pressure gives pulse pressure. Dividing rate by stroke volume or multiplying stroke volume by blood pressure produces no meaningful physiologic measurement.
