WebSep 9, 2024 · Flow is the movement of volume per unit of time. Flow is affected by the pressure gradient and the resistance fluid encounters between 2 points. Vascular resistance is the opposition to flow, which is caused primarily by blood friction against vessel walls. Vascular resistance is directly related to the diameter of the vessel (smaller vessels ... WebSBP = Systolic Blood Pressure DBP = Diastolic Blood Pressure Thigh/Arm Circumference = Measured in Centimeters. For example, if the subject is a healthy male with Blood Pressure of 120/80 and thigh circumference of 52 centimeters the lower body equation would look like the following: = 0.912 (120) + .734 (80) + 5.893 (52) - 220.046
