stroke volume is equal to heart rate times the cardiac output
To measure stroke volume, the formula is SV = CO / HR. Stroke volume can apply to each of the two ventricles of the heart, although it usually refers to the left ventricle.
It decreases stroke volume
CO=HRXSV, Where HR is heart rate and SV is stroke volume
Lowers stroke volume
false, stroke volume decreases if the end volume decreases.
stroke volume of an everage person at rest is 70-80ml stroke volume of an everage person at rest is 70-80ml
The stroke volume refers to the amount of blood pumped out of the heart during each contraction. After exercising, a person's stroke volume is increased.
Stroke volume and swept volume are same in any reciprocating engine/compressor.
The relationship between stroke volume and pump rate?
That can be calculated for individual cylinders by the formula :- Pi R (2) x length of piston stroke.
Stroke volume is determined by three factors, altering any of them can change the stroke volume. These factors are preload, afterload, and contractility. The relationship is: SV = P*C/A What this means is that preload and contractility are directly proportional to the stroke volume and afterload is inversely proportional to stroke volume. If you increase preload (within certain limits), stroke volume will increase according to the Starling curve. Increasing contractility (many things can increase this), makes the heart pump harder and increases stroke volume. Increasing afterload decreases stroke volume. All of these can be reversed (decreasing preload and contractility = decreased stroke volume, etc). Get a good physiology book and it will explain all of this very well.
