∙ 9y agoBlood pressure is a measure of the force of the blood on the arterial walls as it flows through them.
Like the pressure a hose pipe is under as water flows through it.
---------------------------------------------------------------------------------
It is often represented as a number. Such as 120/80 mmHg.
The first number (120) represents the systolic blood pressure, that is, the force of the blood as it is actually pumped down the arteries by the heart i.e. as the heart contracts or squeezes.
The second number (80) is the diastolic blood pressure, that is, the force the blood exerts on the arterial walls while the heart is at rest, in between beats.
The mmHg is simply an old measurement of pressure that is still used in medicine today.
Systolic - on the beat
Diastolic - between the beat
The systolic (beat) pressure is always higher than the diastolic (rest) pressure as the systolic pressure is the force of the diastolic blood pressure plus the force of the heart squeezing, or pumping the blood.
--------------------------------------------------------------------------------------------
Blood pressure is a result, or determinant, of two things:
The cardiac output, and the peripheral resistance.
The cardiac output (the volume of blood the heart squeezes into the arteries, the higher the cardiac output, the higher the blood pressure) it is measured in ml per minute.
The total peripheral resistance, is the resistance blood vessels (arterioles/little arteries) offer to blood flow. Resistance is either increased via constriction (closing) or it is decreased via dilation (opening) of the blood vessels.
Thus,
Blood pressure = Cardiac output X peripheral resistance.

And finally, to what I suspect is the answer you are looking for...
The ranges of blood pressure.
If a persons blood pressure is too high it is called hypertension
This causes a whole host of problems, by putting excessive strain on the heart and arteries.
It is a major risk factor for not only heart attacks but strokes, aneurysms, etcetera.
High blood pressure is categorized into stages, 140/90 would be considered HIGH stage 1.
Optimal <120/<80
Normal 120/80
High-Normal 130/85
High stage 1 - 140/90
High stage 2 - 160/100
High stage 3 - 180/110
Obviously as the blood pressure rises so does the risk and severity of the diseases it causes.
If a persons blood pressure is low, it is called hypotension, a blood pressure of 100/60 and lower indicates low blood pressure, but it is of little concern, contrary to the popular misconception that it is just as damaging as high blood pressure.
While low blood pressure can be indicative of other health problems, generally speaking, in normal, healthy, physically active adults who are in good general fitness, it is of little concern, unless of course it is causing problems such as fainting or shock.
I hope this answers your questions.

∙ 12y agoBlood pressure readings are taken to determine the overall health of a person's cardiovascular system. There is no single reading that is considered normal because all individuals have a particular physique. However medical science has set standard ranges for blood pressure. Physicians examine the results on a patient and compare it with other information on the individual's height, weight and medical history. If the doctor determines that a patient has an abnormally high blood pressure, additional tests may be conducted to reach a diagnosis.
Acceptable Blood Pressure RangeFor adults over the age of 20 the blood pressure reading is considered normal if it falls somewhere close to 120/80. The first number is the pressure in millimeters of Mercury when the heart is contracting. This is called the systolic number reading. The second number represents the pressure in millimeters or mercury when the heart is relaxing between beats and is called the diastolic number reading.
The American Heart Association recognizes a reading close to or slightly below 120/80 as normal blood pressure range. Patients may be classified as prehypertension if the systolic reading is between 120 and 140, or the diastolic reading is between 80 and 90.
High Blood Pressure RangeIf the patient's systolic reading is between 140 and 160 he or she may be considered as having Stage 1 hypertension, especially if the diastolic reading is higher than 100. Stage 2 hypertension means the individual has systolic and diastolic readings above 160 and 100, respectively. A hypertension crisis diagnosis may be reached if the reading is greater than 180/110.
Further Testing May Be NecessaryA person's blood pressure varies according to the physical demands the body is placing on the heart and circulatory system. Blood pressure is always taken when the individual is in a resting state. Even if a higher than normal reading is experienced the doctor will often want to take the blood pressure several more times over a period of a few days. This extra testing may prove that the first reading was an aberration. Blood pressure can also be affected by the taking of prescription medications, lack of sleep or poor dietary habits.
If a physician determines that the patient has higher than normal blood pressure, several treatment options will be considered. The taking of prescription blood pressure medications and a change in diet, along with increased exercise may be recommended.

What are the range of the blood pressure?
In the US and UK, the acceptable blood pressure is generally measured as 120(systolic) over 80 (diastolic). However, the desirable blood pressure is anywhere from 90-119 systolic over 60-79 diastolic. Anything above 120/80 could indicate Prehypertention, and anything below 90/60 could indicate Hypotension, both potentially serious conditions, if left untreated.
What does a low diastolic blood pressure like 136 over 62 indicate?
Low diastolic blood pressure can indicate heart problems, endocrine problems, dehydration, allergies, blood loss, infection, or pregnancy. It can cause dizziness and fainting.
Important Facts About Blood Pressure Range?
Blood pressure ranges are incredibly important to understand for people with or without blood pressure issues. In most simplistic terms, blood pressure is the force exerted on the walls of bodily arteries by circulating blood. The most favorable blood pressure levels are less than 120/80, or one hundred twenty over eighty. If blood pressure becomes higher than this number, than a person may be in the mild, moderate or severe high blood pressure ranges. The higher blood pressure ranges need to be treated with medicines or they will be severely detrimental to a person's health. While high blood pressures are not to be taken lightly, it is important to understand that at certain times, a person's blood pressure can reach higher numbers without too much concern involved. For instance, blood pressures will be naturally higher when a person is physically exerting themselves. However, if a person's blood pressure is high while at rest, it means that their heart is overworked and their artery walls have unneeded extra stress being exerted upon them. Of course it is also important to remember that low blood pressure is just as much of a problem as high blood pressure, so it is wise to know blood pressure guidelines. Below normal blood pressure numbers will hypotension, or low blood pressure. Normal blood pressure ranges from 90-119/60-79, or ninety to one hundred nineteen over sixty to seventy-nine. Therefore, low blood pressure ranges will be below these normal blood pressure ranges. Pre-hypertension ranges, or mild blood pressure ranges, will be anywhere from 120-139/80-89, or one hundred twenty to one hundred thirty-nine over eighty to eighty-nine. Stage one hypertension, or moderate blood pressure ranges, will be from 140-159/90-99, or one hundred forty to one hundred fifty-nine over ninety to ninety-nine. Stage two hypertension levels, or severe blood pressure levels, will range anywhere 160/100, or one hundred sixty over one hundred, or higher. It is critically important to know these levels, especially if you have a personal or family medical history of blood pressure problems. Even if you have never had blood pressure problems personally, it is important to know these numbers for future reference. Blood pressure can be measured with certain medical devices that can be purchased in many stores, so be sure to invest in an instrument to measure your own blood pressure in the future if you have not done so already.
What are the normal ranges of blood pressure?
Systolic under 120, Diastolic below 80
When the systolic blood pressure and diastolic blood pressure are too close together what might that indicate?
Reduced blood flow ... but its usually an artifact of measurement rather than real.
When measuring blood pressure what does 180 over 90 mean?
That reading would indicate a high blood pressure, 120 over 80 would normal.
What does a widen pulse pressure indicate?
regurge of blood due to weak heartvalve
Describe the normal ranges for each type of blood pressure measurement?
Blood pressure measurements are a combination of the systolic and diastolic pressure. Ideally, blood pressure should be under 120 in the systolic measurement and 80 in the diastolic measurement, commonly notated as 120 over 80.
