Blood pressure show be lower to increase perfusion and cardiac output?
How does that work?

Lower blood pressure means less output and perfusion.

If lung searing from inhaled heat
occurred, then there may be either a pneumo or hemothorax, requiring a
chest tube.

Hemothorax and pneumothorax are caused by *mechanical* injuries NOT
*thermal* injuries.

Again, you're plucking "facts" out of a hat as if they're the end all
of rationales in physiology. Here's a clue for you; look up "preload"
and "afterload" and see if you can figure out what they mean in terms
of perfusion, pressure, and cardiac output.

Hemo-pneumothoraces can result from burns simply because the burn will
damage the lung; allowing for either air or blood from injured
pulmonary tissue to vent where it would not normally go.

Also from one of the links that you provided:

"...Information on this web site is provided for informational

You're reading, but you're not understanding.

You can't possibly be serious on this question, because your "let's say..."
conditions are eliminating 90% of the bodies normal response. Your
conditions have limited the argument to a decomposing pile of tissue unable
to mount a healing response, much less an inflammatory response. You are
like the person who takes the hands of his watch to a repair shop without
the watch because the hands weren't moving and you expect the watch
repairman to fix the problem.

What is the point of this?

Hi:

I wonder what would happen if each of my voluntary muscles [including
speech muscles; excluding breathing muscles] were completely relaxed
into a state of total paralysis [and could not contract or "un-relax"
no matter how much stimulation those muscles recieved] and someone
surrounded me with oxyacetylene flames and burned the skin all around
my body resulting in extensive superficial partial-thickness burns.
Lets also say -- for some magical reason -- the burns did not cause
immune responses [or affect my immune system at all], inflammatory
reactions, or hypovolemic shock, and that my environment was totally
sterile [free of infective agents], free of allergens [and other
irritants] and that the burns had no affect on my respiratory system at
all. In addition, let's say that the pain I experienced did not cause
hyperventilation and did not affect the respiratory system or immune
system at all and that I was totally conscious during this burning
procedure. Last but not least, lets say I am otherwise [other than the
burns and paralysis] totally healthy. What effects would the
excruciating pain of the burns have on my nervous and circulatory
systems? Would those effects be fatal?

Due to the paralysis, I would obviously be unable to scream or flinch
no matter how much pain I am in.


Thanks,

Radium

Radium,

Here is the problem with your question. In your question you eliminated the
conditions that would allow the cardiovascular or the nervous systems to
respond at all. We as a group need more input as to what you actually
understand about the question you are asking. The way you have put the
question seems to point to a lack of knowledge about the entire process.
You would probably get a more positive response if you provided more
information...

The short answer? Anyone that burns himself like that is probably
going to quickly die. You can look up the "whys" in a textbook. And if
you don't like what you read, you can selectively tear out pages until
you get a scenario that fits your agenda, whatever the hell it is.

In my hypothetical case, I guess the victim's cardiovascular system
would go out of control from the stress and pain.

Extreme stress can kill either by overworking the heart [sympathetic
overload] or relaxing it way too much [parasympathetic overreaction].
If the cardiovascular system is over-stimulated, the heartbeat can
become disorderly and the 4 chambers of the heart stop communicating
with each other. This can be fatal on its own. In other cases, after
over-stimulation, blood pressure rises excessively, this causes the
parasympthetic nervous system to kick in which in turn results in a
decrease in the strength and speed of the heart. This causes a dramatic
decrease in blood pressure. To make things worse, the parasympthetic
system causes blood vessels around the body to widen causing blood
pressure to fall even further. This extremely low blood pressure
results in loss of blood supply to vital organs and is therefore fatal.

Is my guess correct?
