Blood Pressure (Common Errors in BP Readings (False Low Diastolic Readings…
Blood Pressure
-
5 Determinants
-
Viscosity The thickness or viscosity of blood, determined by the percentage of red blood cells found in the blood (hematocrit count)
Peripheral Resistance The resistance to blood flow determined by the tone of vascular musculature and diameter of blood vessels
-
-
Definition
The force exerted on the walls of an artery by pulsing blood under pressure from the heart.
Measured as Systolic/Diastolic Pressure
Normal Readings: Systolic Pressure < 130 mm Hg, and Diastolic Pressure < 85 mm Hg
Systolic Pressure The peak of maximum pressure, when ejection of blood occurs.
Diastolic Pressure The minimal pressure exerted against the arterial walls by the remaining blood in the arteries when the ventricles relax.
-
Hypertension
When the Systolic Pressure > 140 mm Hg, and Diastolic Pressure > 90 mm Hg
4 Grades
Grade 2 Syst. = 160-179 mm Hg, Diast. = 100-109 mm Hg
Grade 3 Syst. > 180 mm Hg, Diast. > 110 mm Hg
Grade 1 Syst. = 140-159 mm Hg, Diast. = 90-99 mm Hg
Isolated Systolic Syst. > 140 mm Hg, Diast. < 90 mm Hg
2 Types
-
Masked Hypertension When the blood pressure reading is normal while the patient is with a healthcare provider but becomes elevated at home
Signs & Symptoms
-Dizziness
-Chest pain
-Headache
-Fatigue
*All of which are caused by decreased blood flow to vital organs. Decreased flow caused by increased peripheral resistance and/ or loss of elasticity in walls of blood vessels.
