what is pulse pressure and what does it indicate?
What is pulse pressure and why are people talking about it? Pulse pressure refers to the difference between the systolic (top) and diastolic (bottom) blood pressure. If your blood pressure (BP) is 120/80, for instance, your pulse pressure is 120 - 80 = 40 mmHg. A pulse pressure of 40 mmHg is normal. Why does this matter? Does it add important information beyond knowing just your systolic and diastolic values?
