Education. All physicians, including surgeons, must first complete an undergraduate degree program, usually in a science area such as biology or chemistry. Following undergraduate school, you then must complete four years of medical school and a three-year residency.
For most people, perfect BP is 120/80, which means that the systolic number is 120 and the diastolic pressure is 80. When wanting to know if a person has perfect blood pressure, it is best to check it various times throughout the day as it can change depending on the time of day and what the person had been doing prior to checking their BP.
As defined by the American Heart Association, the top number, or systolic blood pressure is normally less than 120 (mm Hg, millimeters of mercury), and the bottom number, the diastolic blood pressure is normally less than 80 (mm Hg). In other words, 118/78 is considered normal, but 120/80 is not. Prehypertension is defined as a systolic pressure of 120-139 or a diastolic pressure of 80-89. A systolic of 140 or greater, or a diastolic blood pressure of 90 or greater is defined as hypertension, or high blood pressure. A hypertensive crisis is a diastolic pressure of greater than 110 or a systolic pressure of greater than 180; this requires emergency attention.
