It is among hundreds of artifacts linked to the doomed ship to be sold at auction later this month. 'Unthinkable': This chilling hand-drawn building plan was used to describe how the 'unsinkable' RMS Titanic met its fate.
The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.aving a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension. A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.
The pressure measured when the heart contracts and pumps the blood into the vessels is called systolic blood pressure, and the pressure measured when the heart relaxes and fills up with blood is called diastolic blood pressure. The unit of BP is millimeters of mercury (mmHg). The normal blood pressure range for adults is 120-80 mmHg (systolic should be below 120, while diastolic should be below 80). The ideal blood pressure for men and women (even for women over 40 and for women over 50) can be slightly different.
