How to Read the SYS DIA Pulse
Instructions
-
-
1
Locate the systolic pressure reading on the blood pressure monitor. This numbers is usually labeled as "SYS," and is the top-most reading on the blood pressure monitor.
-
2
Determine where the systolic reading falls on the blood pressure scale. A normal systolic reading is below 120. A reading between 120 and 139 signifies prehypertension, a reading between 140 and 159 signifies Stage 1 hypertension, a reading of more that 160 signifies Stage 2 hypertension, and a reading of more than 180 signifies a hypertensive crisis. If your systolic pressure is over 180, you must seek emergency care immediately.

3
Locate the diastolic pressure reading on the blood pressure monitor. This numbers is usually labeled as "DIA," and is located directly below the systolic on the blood pressure monitor.
-
4
Determine where the diastolic reading falls on the blood pressure scale. A normal diastolic reading is below 80. A reading between 80 and 89 signifies prehypertension, a reading between 90 and 99 signifies Stage 1 hypertension, a reading of more that 100 signifies Stage 2 hypertension, and a reading of more than 110 signifies a hypertensive crisis. If your diastolic pressure is over 110, you must seek emergency care immediately.
