</b>Central arterial blood pressure when it was developed was an experimental technique and was also quite invasive requiring cardiac catheterization, but there has been a rapid development in the science of central arterial blood pressure in a more convenient way and in a more noninvasive way by a variety of methods but the basic principal is applanation tonometry where one can estimate the central aortic blood pressure in a noninvasive way by looking at so called pulse wave analysis or also known as PWA. When you analyze the pulse wave, it is an indirect reflector of central aortic blood pressure.When the heart pumps, it generates the blood pressure and it generates the pulse wave but generated pulse wave comes back to the heart known as reflected wave. The combination of onward namely generated and backward namely the reflected wave is an estimate of central aortic blood pressure. So using a mathematical formula, by looking at pulse wave analysis, these days it has become very easy to estimate central aortic blood pressure in a noninvasive fashion and there is a good correlation between central aortic blood pressure that is measured non-invasively and which is measured invasively. So the stated art now is that central aortic blood pressure measurements have become very reliable, very reproducible, and very predictive of cardiovascular risk profile.
