Measuring Blood Pressure The Novel Way

Recommend to others!

Arterial stiffness is a principle contributor to cardiovascular diseases and it cannot be measured easily. It has great impact on the readings of blood pressure since these readings are dependent on the time taken by the arteries to get back to the normal flow and volume after they get compressed. A novel technique for measuring arterial stiffness has been reported in a periodical Bio medical Engineering Online. This easy and non massive measurement is capable of interpreting the standard oscillometric measurement to quantify the blood pressure and arterial stiffness simultaneously.

The National Heart, Lung and Blood Institute estimates that “about 1 in 3 adults in the United States has HBP. The condition itself usually has no symptoms. You can have it for years without knowing it. During this time, though, HBP can damage the heart, blood vessels, kidneys, and other parts of your body. Knowing your blood pressure numbers is important, even when you’re feeling fine. If your blood pressure is normal, you can work with your health care team to keep it that way. If your blood pressure is too high, treatment may help prevent damage to your body’s organs.”

The arterial stiffness augments the hypertension and this hypertension aggravates the arterial stiffness in worse self perpetuating spiral. The arterial stiffness is concerned with type 2 diabetes and is engaged in the progression of various problems concerning circulatory system. With early detection, you can address the arterial stiffness, with the help of exercises and diet.  Generally the arterial stiffness can be measured with the help of ultrasound and tomography and both of these are complicated to perform, resulting in inaccurate measurements. A team of researchers from Japan determined the arterial stiffness by means of association between the arterial volumes and cuff pressure.

This was measured using the amplitude of cuff oscillations and pulse pressure. Readings were then pooled together to generate the arterial stiffness index. To verify the validity of this new technique, API findings from 100 participants were evaluated to arterial stiffness which was determined by the pulse wave velocity and the ultrasound. The researchers said that understanding the blood pressure provided the similar preciseness of measurement for arterial stiffness like the earlier established techniques. The API matched the arterial stiffness which was measured by tomography and it also found to be correlated with the ultrasound measurement of stiffness of arteries which supplied the heart. Hence by using the oscillating cuffs, early detection of cardiovascular disease was possible.
