Describe the factors affecting stroke volume (SV) and the interaction between stroke volume, heart rate, and cardiac output (CO)? Stroke volume is the amount of blood that is sent out of the heart during the systole stroke of the heartbeat. This is the combined output of both the left and the right ventricles. For a healthy male, this volume is somewhere around 5.6 liters per hour, for a healthy female, 4.9 liters per hour. The factors that could affect stroke volume would be heart disease, any of which narrow the ventricles chambers. Some of these diseases weaken the muscle of the ventricles, causing a decreased heart rate. Atherosclerosis, or hardening of the arteries, can have a dibilitating effect on cardiac output as well.

Heart Rate, Cardiac Output & Stroke Volume Therefore, we can use the equation CO = HR x SV. This equation tells us that the cardiac output equals the heart rate (HR) , which is the number of heartbeats per minute, times the stroke volume (SV) , which is the volume of blood pumped by the ventricles with each heartbeat.If your body needs more blood, then your heart will increase the cardiac output.herefore, our equation looks like this: CO = HR x SV. We know that if you increase the amount of blood being pumped by your heart every minute, what you're really doing is increasing your cardiac output. And from our equation, we see that this means you either increased your heart rate or your stroke volume or both.

Stroke volume Stroke volume is intrinsically controlled by preload (the degree to which the ventricles are stretched prior to contracting). An increase in the volume or speed of venous return will increase preload and, through the Frank–Starling law of the heart, will increase stroke volume. Decreased venous return has the opposite effect, causing a reduction in stroke volume.

Traditional Chinese Medicine (TCM) and Acupuncture for Stroke Acupuncture has been shown to increase blood flow in areas of the brain immediately around lesions caused by a stroke, and so may facilitate brain repair and re-organization to compensate for areas of organic damage. Clinical trials indicate that acupuncture is a low cost treatment with few risks of side-effects.

Central Venous Pressure Factors Increasing Central Venous Pressure. A decrease in cardiac output either due to decreased heart rate or stroke volume (e.g., in ventricular failure) results in blood backing up into the venous circulation (increased venous volume) as less blood is pumped into the arterial circulation.

Describe the factors affecting stroke volume (SV) and the interaction between stroke volume, heart rate, and cardiac output (CO)? Cardiac Output = Stroke Volume X Heart Rate. Stroke Volume = End Diastolic Volume - End Systolic Volume. Although the concept applies to either ventricle, usually stroke volume measurements are made on the left ventricle, which has the larger workload. The Frank-Starling Lawstates that the larger the preload, or volume of blood entering the heart during diastole (relaxation) the greater the...

Factors That Will Increase Cardiac Output Increases in heart rate alone did not increase blood flow in the tested volunteers and, in fact, decreased the amount of blood ejected with each beat. When muscles perform work, their demand for more oxygen causes their blood vessels to enlarge, allowing more blood to flow to them and back to the heart.

- A stroker is an engine with increased or decreased stroke. By increasing an stroke (the distance the piston travels in the cylinder bore), we gain displacement. By the same token, when we decrease an engine’s stroke, we reduce the distance the piston travels in the bore. This changes when and how the engine makes power.

Factors That Influence Stroke Volume & Heart Rate Stroke volume and heart rate combine to form cardiac output, which the National Strength and Conditioning Association (NSCA) reports is the total amount of blood ejected to working areas of the body. Stroke volume refers to the amount of blood that is ejected with each systolic beat, and heart rate is simply the rate at which the heart beats, usually calculated in beats per minute. Both stroke volume and heart rate are interrelated, and an increase in one often results in a decrease in the other. Stroke volume and heart rate are influenced by a variety of factors, most notably exercise, neural and hormonal factors, and diet and medication. Video of the Day
