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.
How does an increased or decreased cardiac output impact the body?
A decrease or increase of cardiac output in the body can result to several health problems depending on the body's health conditions. A stroke is prevalent if there is an increase of cardiac output that cannot be handled by the system. Lack of oxygen in the brain is an effect of a decrease cardiac output on the other hand.
How does tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
What effects cardiac output during the first few stages of exercise?
Cardiac Output is computed as your heart rate times your stroke volume (volume of blood ejected from the heart each beat). The main contributor when exercising is an acceleration in heart rate. Stroke volume can be increased, but only by prolonged aerobic training. To answer your Q, HR as has the main effect on cardiac output during the first stages of exercise.**The first few stages of cardiac exercise will 'affect' cardiac output, not 'effect' it. If you don't know the difference between the two, you should not be asking a question such as this...
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.
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
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
Is stroke volume usually larger than cardiac output?
FALSE
