Wristech Blood Pressure Monitor

It's so small you can take it anywhere. It's the battery operated Wristech blood pressure monitor that tells your blood pressure at the touch of a button but Does It Work?

It's the blood pressure monitor that wraps around your wrist. And is small enough to take anywhere. Press one button and it shows your systolic and diastolic readings as well as your pulse rate.

We've brought the Wristech blood pressure monitor to the Waikiki fire station to put it to the test. People come into this station every day to take advantage of the Honolulu Fire Department's free blood pressure screening.

Jolinda Kirkpatrick of Liliha has come in to get her pressure checked. Following the directions, the Wristech monitor is strapped onto her wrist. She then elevates her wrist to the level of her heart.

As soon as you hit the start button, you can feel the monitor build up pressure and begin to squeeze your wrist. It flashes a series of numbers at you but then stops and reads out your blood pressure and pulse. Systolic on top, diastolic in the middle, pulse rate on the bottom. With the Wristech, Jolinda's blood pressure is measured at 130 over 78.

Then, firefighter Conrad Nakamoto measure's Jolinda's pressure using the standard arm cuff method. After several pumps it measures 120 over 60. Not even close to the Wristech's readings of 130 over 78.

"Her high end on her blood pressure is just a flutter and it starts really popping at about 120, I really hear it. So, I don't think it's that high at all," says Nakamoto.

George Tuerlings, vacationing here from Vancouver, British Columbia, has also come in to check his pressure. 

Again, the numbers change as the Wristech squeezes your wrist. George's blood pressure, according to the Wristech, is 150 over 94. Using the standard cuff method, George's pressure is 140 over 90. That's a little closer, but still different from 150 over 94.

So, what's the final word on the Wristech. None of the readings on the Wristech ever came close to the standard cuff method. And we tried it twice on each subject just to make sure. But if you want a Wristech blood pressure monitor of your very own, it'll cost you about 50 bucks.
