Hypertension: Abnormal blood pressure above 120/80, Prehypertension systolic pressure ranging from 120 to 139 mm Hg or a diastolic pressure ranging from 90 to 99 mm Hg. Sage 1 Hypertension: Systolic pressure ranging from 140 to 159 mm Hg, diastolic pressure ranging from 90 to 99 mm Hg. Stage 2 Hypertension: Systolic pressure of 160 mm Hg or higher a diastolic pressure of 100mm Hg or higher. (WWW.Mayclinic.com/health/high-blood-pressure ) Blood pressure is the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries, the more your heart pumps and the narrower the arteries the higher the blood pressure. It is measured by two numbers Systolic (top number: when the first heart beat is heard after releasing the pressure on the blood pressure cuff), and Diastolic (bottom number: the last heart beat heard when releasing the pressure on the blood pressure cuff.) Hypertension is classified as a negative feedback system. (see figure on Pg. 728 7th edition A&P copy wright 2007 Elane N. Marieb &Katja Hoehn) Influence of selected hormones on Variables affecting blood pressure (see table 19.2 Pg. 129 7th edition A&P copy wright 2007 Elane N.

Respiratory System
With Hypertension the body is unable to maintain homeostasis because the heart is unable to maintain a proper heart rate. This may be due to a multitude of diagnoses the Pt. may have. Some Factors of Hypertension include: (Pg. 733, 7th edition A&P copy wright 2007 Elane N. Marieb &Katja Hoehn) Smoking: Nicotine enhances the sympathetic nervous system’s vasoconstrictor effects, thus narrowing blood vessels, and causing high blood pressure. Diet: Dietary factors that contribute to Hypertension, high intake of sodium: Causes the body to retain fluid, thus increasing...
