stroke volume =end diastolic volume - end of systalic volume. But how to measure these volume i don't know?
The formula of volume
The volume of a triangle can be calculated with the formula: volume=1/2*length*width*height.
There is no volume formula for an oval(4/3)*(pi)*(r1)*(r2)*(r3) is the formula for an oval
the formula for the volume of a cuboid is length x breadth x height
Mass (M) x Volume (V) is not the formula for anything. Mass multiplied by Volume is the formula for density. Mass multiplied by velocity (speed with a direction) is the formula for momentum.
Stroke volume is used to measure the heart rate and arterial pressure. Most people who have had a heart attack or stroke or are at risk of having either of these issues must have their heart tested using stroke volume.
Stroke-Volume
false, stroke volume decreases if the end volume decreases.
Lowers stroke volume
That can be calculated for individual cylinders by the formula :- Pi R (2) x length of piston stroke.
Cubic inches is the total volume of all cylinders. If you wanted to know the cubic inches of a particular engine you would measure the diameter of the cylinder bore and the stroke of the crankshaft, then use your calculator to figure out the total volume. The formula for the area of a circle is pi times the radius squared. The formula for the volume of a cylinder is area of the circle times length (stroke) of the cylinder. Once you have the volume of the cylinder you can multiply that number by the number of cylinders for total volume (displacement).
Stroke volume and swept volume are same in any reciprocating engine/compressor.
CO=HRXSV, Where HR is heart rate and SV is stroke volume
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.
No. Stroke volume is the amount of blood that is pumped out of the heart with each heart beat.
The relationship between stroke volume and pump rate?
There are a number of long term effects on stroke volume. These may include reduction in blood pressure and capillarisation among others.
