--heart ventricle-psi calc--
note--
a volume modifier is needed to complete the calc..."radius x 2 x 360 x specific gravity = adjusted weight of fluids/volume"--
example( "left ventricle")--
.1 grams vein weight per mm x 3,000 mm vein length + adjusted fluid density( 2 mm radius x 2 x 360 x 1.060 specific gravity of blood) + 100 grams of weight/pressure applied to the exterior of the vein = total grams of pressure required, to keep the entire length of the vein expanded/open, and displays the pressure in the "ventricle" being studied( right/left)...then, calc to "psi"( grams x 0.00220462) = 4.246979968 "psi" in "left ventricle"/"psi" in all veins from it--
calc complete...happy time-- :o) dancing is permitted depending on venue...
p.s. : i have taken the liberty of guessing wildly about the values/weights of the veins...actual weighing of 1 mm of vein, would give more precise values, also, the diameter of veins change in the body, so, a mathematical average diameter, needs to be decided upon, to get good numbers...i will leave it to the medical community, to "chuck-it-up" a tad, and get nice figures...if perfected, i feel this calc might be able to determine overall vein restriction, based on expected results, from healthy subjects...perhaps??...the question remains, is this pressure value congruent with the value within the heart's "left ventricle"??, if close, but not exact, a modifier to increase numbers "laterally", may be needed( specific gravity x 100, is an example), i feel that the number is already extremely close though...if not spot on, and accounts for fluid viscosity, as well as exterior pressure--
conclusion--
this little calc also leads me to conclude, that in the case of a head injury, and the swelling that results, causing hemorrhaging, or the death of the subject...the fatality is likely from the increased pressure within the "aorta", due to swelling within the brain( as pressure applied to the exterior of the brain's vein-structure, from swelling, also increases pressure numbers drastically ,within the "aorta")--
system failure--
as for the common reason that the heart fails, due to high blood pressure/constricted arteries, i am going to hazard a guess that enlargement of the smaller, high pressure chamber, of the "left ventricle", is the primary cause of complete failure of the system...ask a "car-guy", compression is everything, increase the chamber volume in the heads, the slightest bit, and you're going slow...or stopping, depending on how much you increase the volume...restoring chamber size, and eliminating any flow restrictions in the system, is what works for cars...ask a doctor about repairs on people--
damn-the-spell-check( just do it)--
for now, i have foregone "spell-check", in the interest of science...i am posting this to my blog "digitaldoodlesandmind-farts.blogspot.com/" very soon...and will workout "the little stuff", there--
best wishes, john kruschke :o)
note--
also...i feel that the value of pressure in the "right ventricle" is a negative number... - 3.47 from the draw of the "right ventricle", pulling the returning blood from the extremities...back to the heart, indicating that the return veins are self-supporting, or hard/stiff, to remain open under negative pressure...meaning, that the "right ventricle" basically converts negative pressure, to an equal positive pressure, in the "aorta", after the "right ventricle" contracts...
more later, my phones battery is low-- :o)
P.S. : i figure there are about 500mm of veins from the "aorta" to the head, so, if you adjust the calc for the "left ventricle" above, for the shorter length from the brain to the "aorta", you get the following gimbals...
the math( "aorta")--
.1 grams of vein weight per mm x 500 mm vein length + adjusted fluid density( 2 mm radius x 2 x 360 x 1.060 specific gravity of blood) + 10 grams of weight/pressure applied to the exterior of the vein = total grams of pressure required, to keep the entire length of the vein expanded/open, and displays the pressure-value in the "right ventricle"/"aorta"( 1586.4 grams)...calc grams to psi( 1586.4 x 0.00220462) = 3.49740917 psi present in the "aorta", and the veins coming from it, to the head--
note #1--
also of note...i believe that the lower pressure veins within the skull, have the added advantage of the bone of the skull, preventing direct pressure upon them...allowing the brains vein-structure to resist pressure increases, very well( due to the skull not compressing easily, unlike the tissues in the arm...protecting the "right ventricle", and "aorta", from over-pressure damages( i feel that pressure on a vein, from the "source ventricle", or "aorta", will increase the pressure-value in the "ventricle"/"aorta", directly, in relation to the amount of pressure applied to the exterior surface of that ventricle's vein)--
note #2--
--( i believe that the "right ventricle", and the "aorta", should have nearly the same pressure...although a slight increase is likely, from the action of the "right ventricle" pumping into the "aorta", before being pumped into the smaller chambered "left ventricle", and becoming the highest pressure outlet of the heart)--
summary--
so, the numbers may go, -3.00 psi in the "right ventricle", to +3.49740917 in the "aorta", to +4,246979968 in the "left ventricle"...or something close to that...i would seem that the heart is actually a suction pump, that converts to a positive pressure pump, with two separate pressure outlets, that have two different pressure values( the "aorta", and the "left ventricle")--
an epiphanny--
to test these values, i believe that a simple large-bore syringe, with a small pressure gauge, epoxy'd to the side of it, that goes from -10 to 0, to +10 psi, might work.??..by simply gluing the gauge to the side of the syringe, a physician might be able to test pressures within the veins, from both the right, and "left ventricles"( i feel that they are the "carotid artery", and the "femoral artery", but i really have no clue there...a med student/doctor would need to figure that out)--

--i feel that this B.S., is really neat B.S., of use to start a discussion with your doctor, and nothing more( do not try at home, or anywhere else...naturally applies here)--
