Blood Pressure

Systolic vs. Diastolic Blood Pressure Range - Units = millimeters of mercury

The above chart is also available in Portuguese - Portuguese Blood Pressure Chart. Many thanks to Salomao Fresco for providing it. Human Blood Pressure Range Diagram The 1st Number: Systolic pressure is the pressure generated when the heart contracts. The 2nd Number: Diastolic pressure is the blood pressure when the heart is relaxed. What is Normal Blood Pressure? Buy and use an automatic blood pressure monitor. Compare your BP reading with the numbers on the chart above. Draw a line from your systolic pressure to your diastolic pressure. Is the slope of the line about the same as shown on the chart? Where do YOU fit in? What are your risk factors? Are your blood pressure readings within the normal blood pressure range? Should you take anti-hypertension medication to lower your blood pressure? Normal human daily Blood Pressure Range can vary widely, so any single blood pressure monitor reading is not reliable. BP monitor readings must be taken at different times of day, to determine AVERAGE blood pressure levels over time. What is important is your AVERAGE BP, or MAP (Mean Arterial Pressure) over time. Or, where are those numbers sitting MOST of the time? Normal MAP is about 93 mm of mercury. Lowering High Blood Pressure Tactics Download a 1-page printable .PDF file of the Blood Pressure Chart above. For the scientists among you: The pressure of 1mm of mercury = 0.019337 PSI. A systolic blood pressure of 2 PSI is good, a systolic blood pressure of 3 PSI is not good.
