Hypertensive emergency means blood pressure is so high that organ damage can occur.

The patients in the study had a mean blood pressure at the outset of about 160 over 102 millimeters of mercury.

Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles.

Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation.

In most studies, sodium sensitivity is defined as the change in mean blood pressure corresponding to a decrease or increase of sodium intake.

Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy.

Patients whose mean blood pressure levels were greater or equal to 140 / 90 mmHg or were under antihypertensive medication were classified as hypertensives.

If mean blood pressure decreased by more than 20%, then more fluids and/or boluses of ephedrine were infused, vancomycin infusion was temporarily discontinued and the patient was excluded from the study.

Those treated with doxazosin in ALLHAT had a mean blood pressure that was 2 to 3 mmHg higher than the mean blood pressure of those treated with chlorthalidone.

Over a 24-week period, the researchers found a reduced blood pressure in the intervention group, with mean blood pressure falling by 7.6 mm Hg (systolic) and 3.3 mm Hg (diastolic) in the mineral salt group compared with the control group.

Although a 2001 study suggested that adults who had been breastfed as infants had lower arterial distensibility than adults who had not been breastfed as infants, the 2007 review for the WHO concluded that breastfed infants "experienced lower mean blood pressure" later in life.
