Diastolic blood pressure (DBP) is the pressure exerted on the walls of the arteries when the heart muscle relaxes between beats. When the bottom number of blood pressure (diastole) is over 100 mmHg, it may be called diastolic hypertension (DHT). Diastolic blood pressure means the blood pressu...
If your blood pressure is consistently 130/80 millimeters of mercury (mmHg) or higher, you will most likely be diagnosed with high blood pressure. In 2017, the AHA updated its definition of high blood pressure from the previous definition of 140/90 mmHg or higher. The guidelines recommend ear...
Pressure is a term that can be defined in a number of ways. Chemistry and physics have different definitions for pressure which imply a similar meaning but different contexts are used. It is one of the fundamental properties associated with the substances which is measured in atm, pascals, ...
The measuring unit for blood pressure is millimeters of mercury (mmHg). Normal blood pressure is less than 120/80 mmHg, which is said out loud as "120 over 80". However, since everyone is different, the numbers might be slightly below or above the norm. ...
Pressure is defined as the force acting over a unit area. The standard unit of pressure is the pascal (Pa), named after the scientist of the same name. Other than that, pressure can use other units, like the bar, atm, mmHg, Torr, and ...

Such blood pressure levels are infrequent in westernized societies. The target blood pressure goal for treated hypertensives is higher at 140/90 mmHg but is infrequently achieved. Select individuals at high absolute risk of cardiovascular disease events and/or with specific conditions (notably diabetes,...

What is Pressure? Technical Information Vacuum Technology Since vacuum is described as a “reduced pressure” we must have some understanding of what pressure means. There are two ways of presenting it: every-day experience with atmospheric pressure...
