Best Answer: This is pretty close to simple English although HDMI is a pretty technical standard. HDMI means a simpler and higher-quality entertainment experience. It provides the highest possible uncompressed video and audio quality over a thin, easy-to-use cable with a simple, consumer-friendly connector.
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?
A pulse pressure lower than 40 may mean you have poor heart function, while a higher pulse pressure may mean your heart's valves are leaky (valve regurgitation). The most important cause of elevated pulse pressure is stiffness of the aorta, the largest artery in the body. The stiffness may be due to high blood pressure or fatty deposits on the walls of the arteries (atherosclerosis). The greater your pulse pressure, the stiffer and more damaged the vessels are thought to be.
