Page 13: Systolic And Diastolic Blood Pressure
Systolic and Diastolic Blood Pressure When ventricles (the part of the heart that pumps blood) contract and pump blood out of the heart, the blood pressure reaches its maximum value in the cycle, which is called systolic pressure. When the ventricles relax, the blood pressure reaches its minimum value in the cycle, which is called diastolic pressure.
Page 14: Standard Blood Pressure Classification
Standard Blood Pressure Classification The chart below is the standard blood pressure classification published by the American Heart Association (AHA). If you have been diagnosed with high blood pressure (hypertension), the AHA recommends keeping your blood pressure below 130/80 mmHg. Blood Pressure Category Systolic mmHg (upper#) Diastolic mmHg (lower#)
Page 15: Irregular Heartbeat Detector
Irregular Heartbeat Detector An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is measuring the systolic and diastolic blood pressure. During each measurement, the monitor records all the pulse intervals and calculates the average: If there are two or more pulse intervals, the difference between each interval and the average is more than the average value of ±25%, or there are four or more pulse intervals, the difference between each interval and the average is more than the average value of ±15%, the irregular heartbeat symbol appears on the display...
