Which of the following would cause the greatest increase in cardiac output?
Increased heart rate and increased stroke volume
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.
Determined by heart rate x stroke volume?
cardiac output
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 tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
Which statement is correct about cardiac output?
cardiac output is heart rate multiplied by stroke volume,
What is the word equation for stoke volume?
Stoke volume= cardiac output / heart rate
Cardiac output is determined by?
In reality, if you are NOT in cardiac failure, by the venous return. According to most books its the stroke volume times the rate - but stroke volume is not an independent variable.
Cardiac Output is the volume of blood pumped by each ventricle in one minute?
yes or true
What is cardiac-output?
Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV.
What is cardic output?
Cardiac out put is the volume of blood pumped by the heart per minute. Cardiac output is a function of heart rate and stroke volume. The heart rate is simply the number of heart beats per minute. The stroke volume is the volume of blood, in milliliters pumped out of the heart with each beat. Increasing either heart rate or stroke volume increases cardiac output.
