What does the bottom number of blood pressure mean?
930883
The bottom number (diastolic) is the pressure when your heart is resting (between beats).  It's a measure of how flexible / hardened your arteries are.

The diastolic pressure should not vary more than 5 to 10 mm as this represents pressure in the system when the heart is not contracting. An increase in diastolic pressure more than this during exercise would indicate a serious malfunction within the cardiovascular system.

According to the site listed in sources:\n\n\nHow does a blood pressure gauge (sphygmomanometer) work? What exactly is blood pressure?\n &#92; \n     \nYour heart is an amazing pump. It works reliably for decades, and it safely pumps blood -- one of the trickiest liquids around. In the same way, your blood vessels are pipes. They take the output from the pump and distribute it throughout the body. A blood pressure gauge is simply a way to measure the performance of the pump and the pipes. \nThere are two numbers in a blood pressure reading: systolic and diastolic. For example, a typical reading might be 120/80. When the doctor puts the cuff around your arm and pumps it up, what he/she is doing is cutting off the blood flow with the pressure exerted by the cuff. As the pressure in the cuff is released, blood starts flowing again and the doctor can hear the flow in the stethoscope. The number at which blood starts flowing (120) is the measure of the maximum output pressure of the heart (systolic reading). The doctor continues releasing the pressure on the cuff and listens until there is no sound. That number (80) indicates the pressure in the system when the heart is relaxed (diastolic reading). \n\nIf the numbers are too high, it means that the heart is having to work too hard because of restrictions in the pipes. Certain hormones, like adrenaline (which is released when you are under stress) cause certain blood vessels to constrict, and this raises your blood pressure -- if you are under constant stress, your blood pressure goes up, and it means that your heart has to work too hard. Other things that can increase the blood pressure include deposits in the pipes and a loss of elasticity as the blood vessels age. \n\nHigh blood pressure can cause the heart to fail (from working too hard), or it can cause kidney failure (from too much pressure).

With that blood pressure, I wouldn't worry at all.\n\nOnly once it goes toward 90 for the lower value, you might want to watch out. Not sure about a good indicator for the higher value, probably about 150/160 or so..\nSmoking surely doesn't really help in general, as such also for the blood pressure. So if you wanna do something good for your health, quit smoking...\nIf stress is a factor, I would have a good recommendation from my own experience.

Here are the classifications for blood pressure readings per the JNC 7 guidelines (The Seventh Report on the Joint National Commitee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure):\n\nNormal <120 over <80\nPrehypertension 120-139 over 80-89\nStage 1 hypertension 140-159 over 90-99\nStage 2 hypertension >160 over >100\n\nMake shure you let your doctor know what your blood pressure readings are at home.  This will help him/her adjust your therapy if needed.

Systolic is the top number this when the heart forces blood out of the heart, diastolic is the lower number this when heart is at rest.

Anything below 60 is considered low.\nChronic low blood pressure can lead to life threatening Deep Vein Thrombosis(Blood Clots).

Have your blood pressure checked.

Diastolic pressure is the pressure in the circulatory system in between heartbeats. The blood isn't at any pressure inbetween beats, whether you've just exercised or are sleeping.  If anything, I would guess it might be a little lower if blood vessels dilate (expand) to let off some heat after exercise, as the volume of space for the same amount of blood might increase a little?

First you have to have your blood pressure taken of course. Hypertension or high blood pressure is called the silent killer because it has few outward signs. The standards for blood pressure are set by the us Dept. of Health and Human Services and they are <120 over <80 is normal, 120-139 over 80-89 is pre-hypertensive, 140-159 over 90-99 is stage one hypertension and >160 over >100 is stage two hypertension. These pressures are over time so that a pattern develops, not a single reading. For more info. see the JNC7 Guidelines at http://www.nhlbi.nih.gov/guidelines/hypertension/express.pdf\nLow blood pressure or hypotension is usually seen as a symptom of another problem. Bradycardia (slow heart rate), bleeding, or septic shock are some examples. If you think you may have either it is very important that you speak to a doctor as both can be life threatening.

force exerted by the blood upon the walls of the arteries. The pressure in the arteries originates in the pumping action of the heart, and pressure waves can be felt at the wrist and at other points where arteries lie near the surface of the body (see pulse). Since the heart can pump blood into the large arteries more quickly than it can be absorbed and released by the tiny arterioles and capillaries, considerable inner pressure always exists in the arteries. The contraction of the heart (systole) causes the blood pressure to rise to its highest point, and relaxation of the heart (diastole) brings the pressure down to its lowest point.\n\nBlood pressure is strongest in the aorta, where the blood leaves the heart. It diminishes progressively in the smaller blood vessels and reaches its lowest point in the veins (see circulatory system). Blood pressure manifests itself dramatically when an artery is severed or pierced and the blood (under pressure) ejects in spurts.\n\nSince blood pressure varies in different arteries, the pressure in the brachial artery of the forearm serves as a standard. A sphygmomanometer measures blood pressure in millimeters of mercury; blood pressure gauges that do not use mercury also produce readings that are expressed in terms of millimeters of mercury. The normal blood pressure readings in young people are about 120 mm for systolic pressure and about 80 mm for diastolic pressure, commonly written as 120/80 and read as "one-twenty over eighty." With age, and the constriction of the small arteries and then the larger ones, blood pressure increases, so that at 50 years, normal individuals have a systolic pressure between 140 and 150, and a diastolic pressure of about 90.

Blood pressure is the pressure of the blood against the walls of the arteries.  It results from two forces, one is created when the heart pumps blood into the arteries and through the circulatory system.  The other is the arteries resisting the flow of blood.\nThe higher (systolic) represents the heart contracting and the lower (diastolic)is the heart relaxing between beats.  A blood pressure of 120/80 is considering optimal for adults over the age of 18.  A blood pressure of 140 over 90 is considered hypertension.  Yours of 150/70 is considered mild high and many factors affect blood pressure, one of which is weight.  Others are stress, salt intake, exercise, race, age and alcohol consumption among others.  150/70 is not terribly high but then again the higher the number the greater the risk to good health.  Not being a physician, my advice would be assess your lifestyle and have it checked again.  Don't stress yourself out before visiting your clinic and ask questions that concern you, they are the best resource since they have your health history.  You can also visit www.americanheart.org, which is considered one of the top online resources for a healthy heart.

It depends...What is the systolic reading?  Do you have negative symptoms like dizzyness?  Joggers, athletes...people who do arobic exercise may indeed have lower BPs compared to standard and this is good.  The "mean" blood pressure" is the systolic and diastolic added together and divided by two.  BP of 120/80 has a MBP of 100.  The average acceptable MBP is 100, however the healthy normal for some may well be lower.  The best way to answer your question has much to do with your own medical history and the incclusion of possible negative symptoms.

any number above 200 is effecting your kidneys in a bad was.  If you are above 130 or so you could be diabetic.  My numbers are really bad but when I was found to be diabetic in 1997 my blood sugar was 297.

Was this a "self test" or one supervised by a doctor or cardiologist?  If it's a self test I would advise you to see a doctor before getting on a treadmill again.  In fact, see a doctor anyway.  That's a very high blood pressure.  An increase in diastolic blood pressure of more than 10 mmHg (optimal is <120) during or after exercise represents an unstable form of hypertension, and may be associated with coronary artery disease.  At 236 you could be classified as well above third stage hypertension.  Really, see a doctor.

Or to put in simpler terms, ABI is the ratio of blood pressures in the arm versus the ankle.  In healthy people, the blood pressure in both is the same and the ratio is 1.  In people with peripheral vascular disease, the leg arteries get clogged and the flow there drops down. Less flow means lower blood pressure in those arteries.  In that case ratio of Ankle artery/brachial (arm) artery goes down. The above post delves into the specifics.  Hope that helps.
