NORMAL REGULATION OF BLOOD PRESSURE
•Blood pressure (BP) is the force exerted by the blood
against the walls of the blood vessel.
•It must be adequate to maintain tissue perfusion
during activity and rest.
•Regulation of BP involves nervous, cardiovascular,
endothelial, renal, and endocrine functions.
HYPERTENSION
Classification of Hypertension
•Hypertension, or high BP, is defined as a persistent
systolic BP (SBP) 140 mm Hg, diastolic BP (DBP)
90 mm Hg, or current use of antihypertensive
medication.
HYPERTENSION IS CLASSIFIED AS
FOLLOWS:
• Blood pressure categories in the new guideline are:
Normal: Less than 120/80 mm Hg;
Elevated: Systolic between 120-129 and diastolic
less than 80;
Stage 1: Systolic between 130-139 or diastolic
between 80-89;
Stage 2: Systolic at least 140 or diastolic at least
90 mm Hg;
Hypertensive crisis!
Systolic over 180 and/or diastolic over 120, with
patients needing prompt changes in medication if
there are no other indications of problems, or
immediate hospitalization if there are Signs of organ
damage.
ETIOLOGY
Primary (essential or idiopathic) hypertension is
elevated BP without and identified cause. It
accounts for 90% to 95% of all cases of hypertension.
Secondary hypertension is elevated BP with a
specific cause. It accounts for 5% to 10% of
hypertension in adults.
