[edit] Low blood pressure
"The clear trend from double blind clinical trials (for the better strategies and agents) has increasingly been that lower BP is found to result in less disease".
- This statement is somewhat confusing and only partially true. although beneficial effect of BP lowering is well documented in studies like RENAAL, IDNT, AASK, HOPE and especially in wisconsin study [1] BP lower than accepted normal protects against renal disease in type 1 DM, but broader situation is much complex. Low BP has higher risk of stroke in CKD patients [2] and higher risk of dementia and depression [3]. Understanding of low blood pressure and effect on disease is still in early stage and not within scope of encyclopedia.--Countincr ( T@lk ) 19:28, 5 April 2007 (UTC)

[edit] Some causes
BLOOD PRESSURE IS SOMETIMES CAUSED BY PEOPLE WHEN THEY GET ANGRY AND THEIR BLOOD PRESSURE GETS HIGH.ALSO BIG/FAT PEOPLE HAS THIS AND THEY HAVE TO TAKE MEDICINE, BUT SOMETIMES THEY GET SO MAD THEY HAVE A HEART ATTACK OR STROKE SOMETIMES.IT DEPENDS ON THE PERSON.BLOOD PRESSURE IS CALL BY OTHER THINGS BUT MOSTLY THAT .
- This is not true. Most blood pressure problems are not due to mental state; 95% have no clear underlying cause. The remainder is due to hormonal or kidney problems. It is a common misconception that someone's "blood pressure is up". It is also a common misconception that high blood pressure leads to headaches. This happens only in the most severe cases.

Omg...you are a complete idiot. All the nurses I work with, and myself included, are laughing our hind ends off.
[edit] Systolic/diastolic correlation?
Is there a correlation or ratio betweem systolic and diastolic components of blood pressure?
- Usually, they follow each other. There are conditions where the two do not keep trend; this is termed "isolated systolic hypertension" or "narrow pulse pressure", resp. JFW | T@lk 00:31, 22 Mar 2005 (UTC)
Is the ideal blood pressure the same for everyone or is it different for youth or kids? I'm seventeen and I got 120/60 which according to the nurse was "Perfect!"(this was during "conscription"). So, is there any diffrence?--84.217.120.7 16:46, 7 June 2006 (UTC)
- BP tends to rise with age (effects of high salt diet in West proposed by my Professor of Haemodynamics vs other cultures where BP tends not to rise as much, also "stiffening" of arteries with age - not just choleaterol being laid down but also changes to the elasticity of the blood vessel walls). Whilst this explains the typical changes with age, none of this is "healthy" as higher blood pressures causes progressively higher risks (so there is no absolute "normal" value) and the longer one lives, the higher the risks become. A healthcare policy based on short-term gains therefore will concentrate on the elderly who have the highest immediate risk, but it is a bit like closing the stable door... - a more sensible approach would be to help people from smoking, being overweight, not taking enough exercise, having too much salt in the diet from an early age - when small changes over time might have better effects (my professor thought the changes in vascular elasticity were probably altered by the western diet by the age of 2 - not very reassuring).
- Over time as the risks of high BP have been recognised, so the proof of the benefits of treatment to progressively lower targets have been demonstrated. As a junior doctor some 15 years ago, 160 was the target but one might not treat until 170, then this dropped to 150 target and then to 140 if other risk factors present (e.g. diabetes, existing angina). Now UK following US for diabetics in setting 135 limit with 130 as ideal (diabetics are at increased risk heart disease even if their glucose level is well controlled).
- To answer your question, the lower a persons blood pressure generally the better (assuming not so low a feel faint on standing up). So for a teenager 95-110 would be ideal, over 130 should be rechecked at some quiet relaxed time, and >140 would need monitoring and careful assessment. '120' during conscription (I wont ask for what) therefore seems fine, a reading at a more relaxed time might well be a little lower. David Ruben Talk 17:49, 7 June 2006 (UTC)
[edit] Sleep and pressure
How does sleep effect your blood pressure? what can happen to you with high blood pressure
- I believe that recent results show that blood pressure peaks early in the morning, before you rise, which is not what was believed before. Consequently the best time to take medicine for blood pressure is at night. PLEASE confirm and source before adding this information to the article. Pol098 01:54, 21 May 2006 (UTC)
[edit] incomplete ¶
The larger arteries, including all large enough to see without magnification, are low resistance (assuming no advanced atherosclerotic changes) and conduit vessels with high flow rates but producing very little pressure drop. For instance, about 5 mmHg mean pressure decrease in the blood flow traveling from the heart all the way to the toes is typical, assuming the individual is supine (horizontal with respect to gravity).
This paragraph is icomplete without some mention of how far the blood pressure falls through the capillaries; the readers deserve context to compare that 5 mmHg figure to. As it is now, scientifically rigorous readers need to scroll all the way down the page to find out that blood returns to the heart at about 5 total mmHg. (I guess that means a drop of ca. 65 mmHg in the capillaries and 5 mmHg in the veins? 5+5+5+65=80?) Doops | talk 04:24, 30 September 2005 (UTC)
[edit] High blood pressure - viscosity, dietary and drug causes
Causes of high blood pressure may be, as I understand it, one or more of flow constriction(s), amount of blood and viscosity. Besides the possiblity of dietary salt increasing amount of blood, are there any dietary or drug factors that are believed to affect esp. viscosity [considering that high vicosity could possibly a cause of TIA by starvation rather than hæmorrhage]. If so, would heavy exercise enhance or mitigate the factors?

How does Blood Pressure vary with age?
- Generally it increases, as the peripheral resistance increases (hardening/narrowing of the arteries etc...) --John24601 22:36, 20 January 2006 (UTC)
[edit] Classification of blood pressure
I think we should add a information about classification of blood pressure. We could adopt the data from [4] (for adults, taken from [5]), but I think a chart such as the upper figure in [6] is easier to understand (note, however, that this figure referes to an older classification).
What do you think? In particular, which is easier to understand: a table with "or" in it, or a chart? -- Woseph 12:08, 14 February 2006 (UTC)
[edit] blood pressur
B.P. IN PARALYSED UPPR LIMB IN PATIENT WITH CVA IS THE SAME AS HEALTHY ONE.
if your extremeties "Fall asleep" easily/quickly, is this caused by low blood pressure?
[edit] B.P. in dogs & cats
The systolic pressure values for dogs and cats is listed as "between 150 and 150 mmHg". I don't have the actual values, but this seems to be wrong.
[edit] Numbness in the thighs when standing still for several minutes.
This problem occurs while standing still for several minutes and goes away as soon as I recline to a sitting position. Does anyone have a perspective on this condition? I'm am taking several medications for high blood pressure.69.143.195.248 17:10, 17 February 2007 (UTC)
- Present in many healthy individuals and usually is not a cause for concern. Can be related to beta blocker. Please remember this is not a page for general discussion. --Countincr ( T@lk ) 18:19, 5 April 2007 (UTC)
[edit] targets are not ranges
Target values are listed. Text refers to ranges. What are desirable ranges? DGerman 13:53, 18 February 2007 (UTC)
[edit] Clarification might help
The ranges for both systolic and diastolic pressures are so varied that there is no true range for diagnostic comparability.
- Is that the dynamic range of those pressures for an individual, under activity, or are you (I actually think) merely meaning the resting arterial systolic and diastolic pressures. The thing is, the final paragraph seems to contradict the opening of the section. And I don't find any mention of how an individual's blood pressure should vary with pulse/activity. I.e. what an individual's ranges of pressures should be.--SportWagon 18:02, 27 April 2007 (UTC)
[edit] Guideline says don't add internal links to See Also?
There are lots of obvious See Also links which are not there, although they are mentioned earlier in the article. Is that because some wikipedia guideline says not to add to See Also articles which have already been linked? If so, I think that's dumb. (I'll explain further if asked). If not, well, I'll go ahead and add a pile more See Also links if no-one else does first.--SportWagon 18:10, 27 April 2007 (UTC)
- I added the page to Categories "Blood", and also "Cardiovascular System". That might fulfill the type of "See Also"s I was thinking of, or at least will when yet more articles are added to those categories. (Aside: Maintenance Categories should be displayed apart from Reference Categories).--SportWagon 16:31, 2 May 2007 (UTC)
[edit] Merger proposed: Home blood pressure monitoring
[edit] Merger executed
I have merged the articles. Some cleanup and shortening may be required; however, since I am not a subject-matter expert, I leave the cleanup to those who are. --B. Wolterding 11:20, 14 June 2007 (UTC)
[edit] Blood Pressure Symptoms
I'm a family doctor in the UK and have an interest in blood pressure
I think the article needs a section about high blood pressure symptoms. I've added the start of one with some references
- There already was a Hypertension article discussing that in detail. If you want to add some of your wording to that, you can retrieve it from the edit history of this current article (Blood pressure). Even in the context this article, your section was inappropriately placed. "Blood Pressure" does not refer only to "High Blood Pressure". But as far as I can see, Hypertension covered all your points in even greater detail.--SportWagon 19:25, 3 July 2007 (UTC)
Thanks - I've no problem with that GordonMarjory 20:14, 3 July 2007 (UTC)
[edit] Blood Pressure Treatment -- remarkable silence of this article
This article fails a potential valuable public health function by providing the interested reader with no pointers to even the rudiments like the value of knowing one's blood pressure or the need to seek immediate medical consult if blood pressure is over 240/180, to say nothing of the value of weight loss, salt restriction, diuretics, ACE inhibitors, etc. —Preceding unsigned comment added by Ocdcntx (talk • contribs) 20:07, 22 July 2007 (UTC)
- Perhaps see Hypertension and Hypotension, etc, which are referenced in the text. And there's a whole section on Home monitoring which, IMHO, should have been left as a separate article referenced from here. Besides, wikipedia is not a public health service. Nonetheless, a reader could infer your suggestions after a complete reading of the text here.--SportWagon 14:39, 23 July 2007 (UTC)
I see you, apparently in response to this, created lots of hypertension links. While that is an action I personally would agree with, beware that there are some who would say redundant links are wrong according to policy. Sigh.--SportWagon 20:11, 24 July 2007 (UTC)
[edit] White-coat Hypertension
There is disagreement among hypertension experts as to whether white-coat hypertension should be considered a true hypertension or not. Many experts, but by no means all, think that white-coat HTN is a variation or a forme-fruste of HTN, caused in part by excessive catecholamine outflows. The section seems to give the impression that there is no disagreement.--Bwthemoose/Talk 19:06, 27 November 2007 (UTC)
[edit] Measurement & pulse rate
describ in datail how the blood pressure is measured in human,if the blood pressure is 120/80mmHg,what will be the pulse rate?78.138.5.82 (talk) 14:34, 5 March 2008 (UTC)
- About a third of the article discusses Blood_pressure#Measurement. There is no ability to make any inferences on the pulse rate from just the blood pressure measurement itself. Of course pulse rate and cardiac ejection stroke volume together define the volume of blood pumped (cardiac output) and this in turn has effect on the blood pressure, but only indirectly. General the level of blood volume & vascular constriction will help set the underlying diastolic blood pressure, but so do things such as passage of fluid out of the blood vessels into the tissues and the return of that fluid via the lymph system. So whilst a person stressed with an increasing heart rate probably will have a higher blood pressure for a while, subsequent opening of the vasculature (ie flushing) may result in overall lower blood pressure and an eventual faint. Likewise someone with a major injury bleeding heavily, may have a very high pulse rate in a desperate attempt to maintain the blood pressure (which itself might not seem unduely lowered) - hence in an ER a patient with BP 120/70 Pulse 64 is probably stable, BP 160/105 P110 is probably a patient in pain or distress, but if BP 110/65 Pulse 110 then possibly haemodynamically compromised and about to go into shock (medical).
- Of course whilst taking the blood pressure measurement, the pulse will be detected (for it creates the intial sound or pressure fluctuations that are recorded as the systolic pressure). Hence automated machines will record the pulse rate at the same time. Manual measurement will given at least a general impression of the pulse rate even if it is not then formally measured.David Ruben Talk 14:53, 5 March 2008 (UTC)
The introduction states that measurement is universally in mm Hg. Not so in Brasil where kPa is the norm. —Preceding unsigned comment added by 82.69.16.174 (talk • contribs)
