Cardiac output will level off as your heart muscle strengthens and your body becomes accustomed to physical activity. For example, when first getting started, walking 5 minutes may be enough to increase your heart rate, but within a few weeks, you will need to increase the intensity of your walk to increase your heart rate by the same amount.

What can decrease the cardiac output?
The cardiac output can be decreased by decreasing the force of contraction of the ventricular myocardium and decreasing the heart rate.
Cardiac Output is the volume of blood pumped by each ventricle in one minute?
yes or true
How does a slow heart beat assist in hibernation?
Low metabolic rate (hibernation) requires low O2 consumption, which requires low cardiac output, which results in low heart rate.
How does exercise affect cardiac output?
The human heart is an involuntary muscle that consists of four chambers: two atria and two ventricles. Its function is to transport oxygen-rich blood throughout the body via the circulatory system, nourishing and energizing living cells. Like any other muscle, the heart can be strengthened with exercise or weakened by a lack of physical activity.Cardiac output is a function of stroke volume and heart rate. An individual's cardiac output can be determined by measuring the total volume of blood that is pumped by a heart ventricle (stroke volume) each time the heart beats (heart rate). The stroke volume multiplied by the heart rate equals cardiac output.A simple mathematical equation is used to calculate the cardiac output of the heart, measured in milliliters per minute.Cardiac Output in mL/min = heart rate (beats/min) X stroke volume (mL/beat)An increase in stroke volume or heart rate of any intensity increases cardiac output.
How much blood is forced out of your heart every hour?
Here you go.http://www.biosbcc.net/doohan/sample/htm/COandMAPhtm.htmCardiac output is the volume of blood pumped by the heart per minute (mL blood/min). 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 (mL), pumped out of the heart with each beat. Increasing either heart rate or stroke volume increases cardiac output.Cardiac Output in mL/min = heart rate (beats/min) X stroke volume (mL/beat)An average person has a resting heart rate of 70 beats/minute and a resting stroke volume of 70 mL/beat. The cardiac output for this person at rest is:Cardiac Output = 70 (beats/min) X 70 (mL/beat) = 4900 mL/minute.
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.
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 heart rate and stroke volume determine?
cardiac output
What is the formula for calculating cardiac output?
CO=HRXSV, Where HR is heart rate and SV is stroke volume
What can decrease the cardiac output?
The cardiac output can be decreased by decreasing the force of contraction of the ventricular myocardium and decreasing the heart rate.
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.
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
What is the effect rest has on Cardiac output?
Rest has a positive effect on cardiac output. This will promote a healthy heart rate in an individual without subjecting the heart to too much pressure.
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.
How is cardiac output calculated?
It's the stroke volume times the heart rate.
