i need an answer to the hemorrage question

Members do not see this ad.

i know its been discussed,but its bugging me that i never actually saw an answer we agreed upon. and cotinara said he/she got lots of heart questions-this will probably be one of em. so heres one more try.

what IS the bodies first response to a hemorrage? i know it has something to do with arterial blood pressure rising or falling...which one is it?

it rises so that clotting factors can reach the area

just think logically. Blood pressure will fall because you are bleeding heavily and the heart tries to do everything it can to keep it up so it starts to beat faster.

So to answer your question bp would fall, and heart rate would rise.

I had this question on my DAT today and put heart cardiac output increases. Don't know if it is right.

Was increasing arterial blood flow one of the choices?

unless you're bleeding tremendously, i would have to disagree on blood pressure falling. right way the heart will pump more blood, so bp should increase right away unless its a huge amount of blood. we may need a full, specific question to answer this one

Sorry for being vague. It was between falling/rising blood pressure and something else. I think I chose a raise in bp.

blood pressure INCREASES

So does it rise or fall!! I say it rises; can we come to an agreement..LOL

No Tissy, unfortunately the court has adjourned until Tomorrow afternoon! 😛

It rises, CASE CLOSED!

should be increase due to homeostasis...

a hemorrhage is when a person is bleeding like an open faucet not a lil cut they dont call that a hemorrhage...for minor wounds it would be a increase in blood pressure but for a hemorrhage it would be a decrease...like when you watch ER they go blood pressure is dropping that happens when a person has a hemorrhage maybe i should have said greys anatomy ER died...it doesnt make sense logically for it to rise but if someone could actually explain that id be intersting to see the logic behind

aaaaaaaaaaaaaah still no resolutions! 😱

I got something specific:

Response to Hemorrhage
Purpose: Maintain or restore blood pressure after major reduction of blood volume.

Increased heart rate, stroke volume.
Constriction of veins, thus mobilizing reserve blood.
Generalized constriction of arterioles to shunt the blood to brain and heart.
Inhibition of digestive function to prevent hypoxia of digestive organs under reduced blood supply.
Constriction of arterioles in kidney, reducing urine output.
Stimulation of renin (a hormone that causes retention of salt and water) secretion by the kidney

This is correct.

I was seriously losing sleep over this-thanks 👍

exactly. You are loosing a lot of blood here. Your heart rate will increase but the BP will still fall because you are loosing a significant amount of blood still.

Ok Im gonna beat this dying horse a little more... when i look up hemorrhage, there are multiple definitions for it. Some say its simply bleeding, some say heavy bleeding, but the common term here is bleeding, and hemorrhage is the medical term for it. MAJOR hemorrage would cause an initial loss in blood pressure, and an increase in cardiac output, but eventually the BP should rise since vessels constrict. How long this takes is beyond the DAT scope.
General hemorrhage acompanies an increase in BP and Card output. What you saw on ER is a SEVERE trauma case.

Again, witch no specific question, we cant really give a specific answer, but if i saw it on the DAT, knowing they test general knowledge, Id go with increases. Just my 2 cents.

Now, I'm very afraid of you 😱

 

[egots]

ok ima revive this horse just so i can beat it some more...

so my final word (made a mistake last time i thought u were talking about blood flow) is that arteriole blood flow will decrease b/c of constriction and when it constricts causes an increase in blood pressure

yes blood needs to go from heart to brain thats it...everything will shutdown until your blood pressure is stable.
