Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
Elevated blood pressure occurs when a person has a systolic pressure of 120-129 mmHg (top number) and a diastolic pressure (bottom number) that's lower than 80 mmHg.
[19] [20] High blood pressure affects 33% of the population globally. [9] About half of all people with high blood pressure do not know that they have it. [9] In 2019, high blood pressure was believed to have been a factor in 19% of all deaths (10.4 million globally). [9] Video summary
In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left arm unless there is some damage to the arm. The difference between the systolic and diastolic pressure is called the pulse pressure. The measurement of these pressures is now ...
With high blood pressure, the force of blood flowing through your blood vessels is consistently too high. Around 75 million Americans have high blood pressure (or hypertension), and almost half of ...
Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
Using the results of the blood pressure test, the health care provider will diagnose prehypertension or high blood pressure if: For an adult, systolic or diastolic readings are consistently higher than 120/80 mmHg. A child's blood pressure numbers are outside average numbers for children of the same age, gender, and height. [40]
If healthy blood pressure is no higher than 120/80, but blood pressure is not viewed as a problem until it hits at least 140/90, consider all the damage that is being done before any intervention ...
