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.
Each time your nurse or physician takes your blood pressure, they are recording two measurements: your systolic pressure and your diastolic pressure. If the two measurements were systolic 110 and diastolic 70, they would be written as 110/70.. Your physician or nurse will describe your blood pressure as one-ten over seventy.. A normal resting blood pressure reading is 120/80. Your systolic pressure (the first and highest number), is the pressure or force the heart places on the walls of your blood vessels as it is working/pumping with each heartbeat.
