  • Measurement Accuracy: Pressure: ±3 mmHg, Pulse: ±5%
  • Measuring Range: 0-299 mmHg, 1 mm Hg intervals
  • Irregular Heartbeat Detection: Alerts irregular heartbeat patterns. An irregular heartbeat is defined as a heartbeat that varies from the average of all heartbeats during the blood pressure measurement. It is important that you are relaxed, remain still and do not talk during measurements.
  • Possible Reasons for BP Variation:
  1. Cuff Size: Many factors can impact your blood pressure readings, including that your cuff might be too small. A cuff that is too small yields a measurement that is higher than the correct blood pressure. The standard cuff size provided is 8.6-16.5"/22-42 cm. If your measurements still seem high, please consult your physician.
  2. BP Varies throughout the Day: An individual’s blood pressure varies greatly (as much as 30 to 50mmHg) from day to day and season to season due to various conditions during the day. For hypersensitive individuals, these variations are even more pronounced.  Normally, blood pressure rises during work or play and falls to its lowest levels during sleep. The best way to get consistent readings is to monitor your blood pressure at least once a day at the same time so that you can minimize the effect that external factors have on the reading. Please consult your physician immediately if you have any doubt about your readings.
  3. White Coat Hypertension: Your blood pressure readings taken in a doctor’s office or hospital setting may be elevated as a result of apprehension and anxiety.  This response is known as “white coat hypertension”
  4. Homes vs. Clinic difference: The healthcare professional may be using a different sized cuff. The size of the bladder inside the cuff is critical for the accuracy of the measurement. This may give you a different reading. A cuff too large will produce a reading that is lower than the correct blood pressure; a cuff that is too small will produce a reading that is higher than the correct blood pressure. There may also be other factors that can cause the difference in measurements.
