Blood Pressure

[rick_vandal]

We're told that blood is thicker than water (but less dense than mercury). A 100 mmHg BP equates to 53 inches of water or say 50 inches of blood. If a giraffe's neck is 100 inches tall and the carotid artery takes the blood up, likewise the jugular returns with a siphon effect with the brain in a negative head state? Discuss.

I don't know anything about giraffes or their blood pressure. But you would be right, if pure physics had anything to do with it, liquid would not stay somewhere in an elevated position given the logic you have used.

I am highly in the region of guessing now but I do know the circulatory system is not uniform throughout. For starters, there are muscle layers in arteries and veins (and arterioles and venules)- these can contract or relax as appropriate. Veins also cheat by using one-way valves to return blood against gravity.

Lastly, the system is sealed in a continuous loop- I'm not sure siphoning will work as the stuff has to have somewhere to go and something to draw from?

It is also a bit more complex than that as well, blood is a clever mixture of materials, including proteins. Not only is it's pressure regulated, but also the protein loading to provide the correct oncotic pressure which is counteracted by the hydrostatic pressure of the blood itself. The body also cheats because it can control blood volume and osmolality. So it's a lot more complex than a regular hydraulic system.

I strongly suspect the physiology of the giraffe has a way of keeping blood in it's head, my wife would tell you as she is the Zoologist and has probably seen surgery on one or dissected one- I do not know for sure but my money would be on it having valves in it's arteries to the blood can only flow upwards and at a rate governed by it's heart.

It is problematic trying to compare mechanical systems with anything involving muscle tissue- it is very powerful for it's weight.

WOW, I struck gold in an hour! Levers and joints are mechanically analogous, though muscles can only contract given ATP. Hydraulically, I have been advised to elevate my swollen leg above my heart as fighter pilots use G suits. It is also fascinating how body temperature is so closely regulated or how infection can upset the thermostat. It is a marvellous machine.

The giraffe has a virtual g- suit and very high blood pressure

Now you are starting to see why I want to study it.

If you are able to view the screen during an echocardiogram, it is mind blowing when you actually see the force at which blood is pumped around the chambers and blood vessels - and that is when at resting rate. And for most of us, it just keeps going, every minute, decade after decade, The heart is an incredible organ and it's no wonder that there are some problems with leaky valves and failing muscles for some.

The closed circuit blood system gets a bit vague at capillarys where the flow expires and the venal harvest begins, lungs accept mostly nitrogen but blood cherry picks O2 using iron. Brilliant!

The way the blood collects and moves gases around is nearly a subject in itself. The removal of carbon dioxide as well is by three possible routes.

And as a thermodynamic 'working substance', heat is distributed. Blood blows your mind.

I hope this answer doesn't get lost in the sea of answers because has the potential to save thousands of lives a year. As you will see with other answers here, there is a lot of general advice, but no one has any plan to follow. Even doctors seem to not really have a plan, just generally wishy-washy advice. I decided to tackle my high blood pressure by using all the available science and studies I could find and by using off-the-shelf products. And it worked. I hope that you will follow this plan— that everyone everywhere will follow this plan. I was able to go from stage 1–2 high blood pressure to 111/73. This is what I do.

1. You need to reduce your salt. I’m sure you’ve seen that statement before. Salt holds onto water which means more blood in your veins and more pressure. You can no longer eat most processed store bought foods. You should not eat any sauces, any dips, any deli meat, hot-dogs, or bacon. They all have A LOT of salt. Start looking up the salt content of stuff and shoot for 1500–2000 mg of salt per day. Even if you cannot get there, any little bit of reduction helps . Reduce some. I usually get 1500–2000. I eat very little salt all day and then eat a normal dinner.
2. You need more potassium every day. Potassium replaces salt in your body, which as you see in step 1 means: less salt, less water, less pressure. So how do you get more potassium? Well, store bought supplements are out because the government controls them and only allow them to be 2–3% of your RDA. This is because if you get too much potassium it can kill you. The government knew that people would abuse it and kill themselves. Shoot for 100% RDA which is 4,700mg of potassium. You can do it in a few ways:

Coconut water. The one listed below is what I drink each morning. It has 27% RDA of potassium.

I'm always a bit of a doubter when it comes to people's recommendations about diet subtractions and additions . I had an old maiden aunt who went absolutely overboard with a magazine "Health for all " edited and sponsored I think by a chap called Stanley Leif . She told me lurid stories from this mag - one about a woman who'd been diagnosed with terminal lung cancer ., and took to using , among other things , a lot of blackstrap molasses . She said this woman had a a very deep retching cough , and one day she parted with a ball of fibrous material , the size of a tennis ball ,curing the lung cancer , never for it to return !. This old Aunt had an abdominal cancer -- and to quote Eliza Doolittle "She died of it ! Not to p1ss on your parade Mr. Kabazzi ! But I have my doubts . I remain to be convinced

she probably coughed up a fur ball.

Blood pressure medication side effects,,on medication about 2 years lots of side effects from amlodipine ,can anyone tell me there stories about there side effects,the last while hard to remember things ,and being on edge like anxiety and tired

Feet swell on some tablets and Cough with others found?

Calcium channel blockers are known to cause swelling of the feet and ankles in some people, if I remember rightly.

 

[Flatlander]

i was getting serious head aches for a long time. Some days I could feel my body pulsing. Went to the local doctor and he took the pressure and when I asked if it was high he chuckled and said it’s about the same as your truck tires. Apparently 185 over 90 something wasn’t good. Put me on viacoram. Next to no side effects that I notice except a bit of a dry cough but I’ve been coughing for forty years so not much new there. Pressure down now to 130 ish so I think I’m Going to live forever. Wife’s not happy thou lol

The leaves in a 100 foot tree expire the water that started out below ground level.

Oh, well. Officially joined the high blood pressure club today. Been having night sweats for 6 weeks so booked appointment with GP a fortnight ago.
In at GP at 7.45am and in local hospital by 8.30am.
Blood pressure 220/150
Been given the works, various bloods, ecg, ct scan, x-ray. Fantastic service after the initial 2 week wait for a GP appointment.
