Now, easy to wear, more accurate watch-like device to measure BPFebruary 21st, 2011 - 1:18 pm ICT by ANI
Washington, Feb 21 (ANI): The way patients’ blood pressure is measured is set to improve thanks to a new blood pressure measurement device.
The new approach, invented by scientists at the University of Leicester and in Singapore, has the potential to enable doctors to treat their patients more effectively because it gives a more accurate reading than the current method used.
It does this by measuring the pressure close to the heart-the central aortic systolic pressure or CASP.
Blood pressure is currently measured in the arm because it is convenient however this may not always accurately reflect what the pressure is in the larger arteries close to the heart.
The new technology uses a sensor on the wrist to record the pulse wave and then, using computerised mathematical modelling of the pulse wave, scientists are able to accurately read the pressure close to the heart.
Patients who have tested the new device found it easier and more comfortable, as it can be worn like a watch.
The new technology will hopefully lead to better identification of those who will most likely benefit from treatment by identifying those who have a high central aortic systolic pressure value. This will be especially important for younger people in whom the pressure measured in the arm can sometimes be quite exaggerated compared to the pressure in the aorta.
Bryan Williams of the University of Leicester’s Department of Cardiovascular Sciences at Glenfield Hospital, said, “it is not going to replace what we do overnight but it is a big advance. Further work will define whether such measurements are preferred for everybody or whether there is a more defined role in selective cases to better decide who needs treatment and who doesn’t and whether the treatment is working optimally.” (ANI)
