Central Time is 2 hours ahead of Pacific Time. The mainland U.S. has four time zones (Alaska and Hawaii each have their own time zâ¦ones, which makes a total of 6 different time zones for the U.S.). From west to east, the mainland U.S.'s time zones are: Pacific Time, Mountain Time, Central Time and Eastern Time.
It includes a sensor strapped to the wrist which can measure the pressure in the aorta, the main artery close to the heart, where high blood pressure does most damage. A sensor in the watch records the pulse wave of the artery, which is then fed into a computer together with a traditional blood pressure reading from a cuff. In most people the pressure in the aorta is 10mm Hg lower than in the arm, but in some, especially younger people, it is as much as 30mm Hg lower.
A cuff on your arm checks your blood pressure during the test. You may be asked to breathe into a tube during the test to determine how well you breathe during exercise. You then begin walking on the treadmill or pedaling the stationary bike slowly. As the test progresses, the speed and incline of the treadmill increases. You can use the railing on the treadmill for balance, but don't hang on tightly, as that may skew the results of the test. On a stationary bike, the resistance increases as the test progresses, making it harder to pedal.
