What two factors is your blood pressure directly dependent on? Moreover, blood pressure is the result of cardiac output increased by peripheral resistance: blood pressure = cardiac output X peripheral resistance. As a result, an abnormal change in blood pressure is often an indication of a problem affecting the heart's output, the blood vessels' resistance, or both.

The number on the bottom is your diastolic blood pressure. It measures the pressure when your heart is between beats. Diastolic blood pressure changes frequently throughout the day. Things that can make diastolic blood pressure change within a few minutes include: 1  Posture. 2  Level of exercise.

Does Blood Pressure Change Depending on Your Position? To what extent do blood pressure measurements vary depending on position, i.e., sitting, standing, or lying down? Also, if the arm is allowed to hang down vertically instead of resting horizontally, what effect does this have on the blood pressure measurements?he ANS normally controls constriction (narrowing) and dilation (widening) of blood vessels and so helps regulate a person's BP. Such a fall in BP with standing is called postural hypotension (low blood pressure), which, when significant, can cause weakness, lightheadedness, and even fainting.
