How Blood Pressure Is Measured-Omron HEM-711


Many people have digital blood pressure measuring devices in their homes today.The Omron HEM-711 is one of the devices have become relatively inexpensive. A cuff is put onto the arm and inflated. As it deflates, the blood pressure (and usually heart rate as well) are measured. The results are usually displayed on an LCD screen. Many of these digital measuring devices like Omron HEM-711 come equipped with memory so that users can keep track of blood pressure readings on different days and at different times of the day for comparison purposes.

Blood pressure is determined by the pressure in the veins and vessels when the heart beats, versus the pressure in the veins and vessels when the heart rests between beats. Readings from Monitor of Omron HEM-711 are expressed as systolic pressure (when the heart beats) over diastolic pressure (when the heart rests between beats). If a reading is 120 systolic and 80 diastolic, the reading is expressed verbally as "120 over 80" and written as 120/80.

A reading of 120/80 is considered optimal for people under the age of 55. Any reading that is above 140/90 indicates a blood pressure reading that is too high, and the patient should see the doctor.So, Omron HEM-711 is easy to use and Omron HEM-711 come with two type-711AC and 711-LDX that are ready in market NOW!
