Prehypertension. Prehypertension, also known as high normal blood pressure and borderline hypertensive ( BH ), [ 1] is a medical classification for cases where a person's blood pressure is elevated above optimal or normal, but not to the level considered hypertension (high blood pressure).

The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...
The difference between the systolic and diastolic pressures is known as pulse pressure, [1] while the average pressure during a cardiac cycle is known as mean arterial pressure. [2] Blood pressure is one of the vital signs—together with respiratory rate, heart rate, oxygen saturation, and body temperature—that healthcare professionals use ...
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [ 3][ 10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [ 2] Hyperthermia requires an elevation ...
e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [ 11] High blood pressure usually does not cause symptoms itself. [ 1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
Diagnosis. The term hypertensive emergency is primarily used as a specific term for a hypertensive crisis with a diastolic blood pressure greater than or equal to 120 mmHg or systolic blood pressure greater than or equal to 180 mmHg. [ 9] Hypertensive emergency differs from hypertensive urgency in that, in the former, there is evidence of acute ...
The patient should remain in the ice bath until their body temperature falls to 102.2 degrees. Then, they can be transported to the hospital. Preparing for heat illness in a warming world
