The ejection rate of the heart is determined by dividing the stroke volume by the end-diastolic volume. The normal end-diastolic volume ranges from 65-240 ml. Normal stroke volume is 55-100 ml.

  • CARDIAC OUTPUT;is the amount of blood ejected from heart.
  • cardiac output=stroke volume multiplied by heart rate.
  • The amount of blood expelled by each contraction of the ventricles is called stroke volume
  • It is actually expressed i n litres per min.
  • In general healthy adults at rest,the stroke volume is approximately 70ml and if the heart rate is 72 per mi9n.then cardiac output is 5 l/min.
  • This can be greatly increased to meet the demands of exercise to around 25 l/min. and in athletes up to 35 l/min.
  • This increase during exercise is called the CARDIAC RESERVE.

when increased blood supply is needed to meet increased tissue reqirements of oxygen and nutrients ,heart rate and stroke volume can be increased.

80 - 100 beats per miniute but if you are really fit you can get it down to 70 or 60 beats per miniute

no anywhere between 60 to 100 bpm is normal mine is the 50 range to a heart rate

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.


Amount of blood pumped by the heart in 1 min?

Compensatory mechanisms to maintain normal cardiac output?

Cardiac output (CO) is determined by the heart rate (HR) and the volume of blood pumped by each beat (stroke volume - SV). Mathematically, cardiac output can be represented by the equation: CO = HR x SV As such, if total cardiac output falls as a result of decreased stroke volume, the heart rate can increase to keep the total cardiac output normal, to a certain extent. Stroke volume is more complicated; it is determined by many different factors, including preload, afterload, competence of the atrioventricular valves, ventricular cavity size, and the strength of the squeeze of the cardiac muscle, amongst others. Any change in one of these factors requires a compensation in one or more of the others to maintain cardiac output.

Which statement is correct about cardiac output?

cardiac output is heart rate multiplied by stroke volume,


What compensations does the body have to do to defend cardiac output if you hemorrhage?

The body will increase heart rate to maintain cardiac output by pumping more blood. It will also constrict blood vessels to redirect blood flow to vital organs and increase fluid retention to help maintain blood volume. If significant hemorrhage occurs, the body may activate the clotting system and release stress hormones to help control bleeding and maintain perfusion to vital organs.


How much blood returns to the heart?

How is cardiac output measured?

Cardiac output is typically measured by multiplying heart rate (number of heartbeats per minute) by stroke volume (volume of blood pumped out by the heart with each beat). It is commonly calculated using techniques such as echocardiography, thermodilution, or impedance cardiography.


What is resting cardiac output?

its not cardiac rest, its cardiac ARREST. which is a heart attack.


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.
