What else can I help you with?
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
Determined by heart rate x stroke volume?
cardiac output
Which statement is correct about cardiac output?
cardiac output is heart rate multiplied by stroke volume,
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
Is stroke volume usually larger than cardiac output?
No, cardiac output is the product of stroke volume and heart rate. Stroke volume refers to the amount of blood pumped by the heart in one beat, while cardiac output is the total amount of blood pumped by the heart in one minute. Typically, cardiac output is larger than stroke volume due to the inclusion of heart rate in the calculation.
What is the difference between stroke volume and cardiac output?
Cardiac output is the blood volume pushed out by the left ventricle per minute. Stroke volume is the volume of blood pushed out of the left ventricle per contraction of the heart (each heart beat). So stroke volume into heart rate / minute gives you cardiac output.
What is the formula for calculating cardiac output?
CO=HRXSV, Where HR is heart rate and SV is stroke volume
What does heart rate and stroke volume determine?
cardiac output
How is cardiac output calculated?
Cardiac output is calculated by multiplying the heart rate (number of heartbeats per minute) by the stroke volume (amount of blood ejected by the heart with each beat). The formula is: Cardiac output = Heart rate x Stroke volume.
Cardiac output is determined by?
Cardiac output is determined by the heart rate and stroke volume. The heart rate is the number of heartbeats per minute, while stroke volume is the amount of blood ejected from the heart with each beat. Cardiac output is calculated by multiplying heart rate by stroke volume.
Does the cardiac output equal heart rate multiplied by stroke volume?
Yes. CO = HR x SV CO - cardiac output HR - heart rate SV - stroke volume
Would an increase in contractility cause an increase to cardiac output?
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
