Healthcare providers consider a normal blood pressure reading to be 120/80 or below. However, it can actually fall anywhere in a range from 90/60 to 120/80 -- it's not just one set number. The number on top of the reading is called the systolic pressure.
To read someone's pulse pressure, you subtract the diastolic blood pressure from the systolic blood pressure. Normal values for pulse pressure are between 30 to 40 mmHg. Pulse pressures may vary in several conditions including hypovolemia, bradycardia, and irregular heart beats.ercury is the only metal that is liquid at room temperature, so it is used to determine measurement of thermometers and barometers. The normal range for the pulse pressure is between 30 to 50 mmHg.
