CASPro Device Promises To Revolutionize Blood Pressure Monitoring
Apparently the hundred year-old practice of measuring blood pressure with a cuff will end soon, when a revolutionary new device will be available to give more accurate blood pressure readings. Does that make you nervous too?
The new device is called the CASPro, because is measures blood pressure in the larger arteries of the heart. It takes a central aortic systolic pressure (CASP) reading, measuring pressure in the arteries closest to the heart, unlike the current methods that measure blood pressure in the arm. The pressure in the CASP area is the most important, because it can cause the most serious damage to the heart.
The CASPro doesn't only provide the most accurate and relevant blood pressure information, but it is non-invasive and easy to operate. It uses a sensor in the form of a watch that is placed on the wrist to record the pulse. The pulse wave is sent through a mathematical program in the monitor that provides a reading that is 99 percent accurate when compared to measuring blood pressure through a catheter at the heart.
Research on the CASPro was conducted in the UK and Singapore. It was published in the Journal of the American College of Cardiology. The intellectual property is owned by a Singapore medical device company called HealthSTATS International.
"I am under no illusion about the magnitude of the change this technique will bring about," said Bryan Williams, professor of medicine at the University of Leicester in the UK. "It has been a fabulous scientific adventure to get to this point and it will change the way blood pressure has been monitored for more than a century. The beauty of all this is that it is difficult to argue against the proposition that the pressure near to your heart and brain is likely to be more relevant to your risk of stroke and heart disease than the pressure in your arm."
Don't throw out your cuff monitors yet. As usual, it will take awhile for this technology to reach your doctor's office, and even longer to be ready for individual market. That's always the rub.
