Flow is the amount of blood flowing through an organ, tissue or vessel at a given time. Perfusion is the flow per given volume or mass of tissue. Thus a large organ could have greater flow but less perfusion then a small one such as an ovary because the ovary receives much more blood per gram of tissue.
Wasted perfusion refers to blood flow that does not contribute effectively to tissue oxygenation or metabolism. This can occur in conditions such as shock, where blood flow is directed away from vital organs, leading to tissue hypoperfusion despite adequate total blood flow. Monitoring markers of tissue perfusion, such as lactate levels, can help assess the degree of wasted perfusion.
For electric charge to flow, there must be a potential difference (voltage) between two points in a conducting material. This difference in potential creates an electric field that exerts a force on the charges, causing them to move. Without a potential difference, charges will not flow.
potential difference between electrodes

Your question is not clear. A current is generated when a group of electrons flow through a conductor, and this happens when there is a potential difference between the 2 ends of the conductor. If you want to know how can we start the flow of electrons it is by creating a potential difference in between the 2 ends of the conductor.
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.

Wasted perfusion refers to blood flow that does not contribute effectively to tissue oxygenation or metabolism. This can occur in conditions such as shock, where blood flow is directed away from vital organs, leading to tissue hypoperfusion despite adequate total blood flow. Monitoring markers of tissue perfusion, such as lactate levels, can help assess the degree of wasted perfusion.
difference between laminar air flow & reverse laminar air flow
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.
Perfusion
Blood flow and tissue perfusion are NOT the same thing. An increase in blood flow does not always mean that there is a parallel increase in tissue perfusion. While blood flow is generally understood as an increase in the total amount of blood flowing into an anatomic structure or region, tissue perfusion is the amount of blood that actually flow through the capillaries of the vascular bed of that structure or region. The important thing to remember is that nutrients and oxygen are delivered to the cells via the capillaries.

Well pulse pressure is systolic (top) minus diastolic (bottom). So the value you get should be between 30-49 to be normal.
