Watts School of Nursing June

Published

Wanted to see who else is going to Watts (Mt Olive) starting in June. I just got my acceptance letter today! Wondering who my fellow classmates will be!

Keyna: I'll be hitting the books in about an hour. I can try to help...

Keyna: look at page 372, 2nd column. The way I read it is an increase in volume causes an increase in HR.

???Question???

Why does decreased blood volume increase heart rate, but decreased venous return decrease heart rate????

Keyna, are you looking at the slides about cardiac output? There's a slide that has info about the regulation of heart rate where it talks about things that increase heart rate (i.e. SNS, hormones, exercise, etc.). The next slide also says "Regulation of Heart Rate" which was a typo. She had a corrected slide up during class that was titled "Regulation of Cardiac Output". The 1st bullet point under that was also a typo and should read "Decreased Cardiac Output" instead of "Decreased heart rate".

So then, increased blood volume and decreased venous return would cause a decrease in cardiac output.

Does that answer your question?

Lady,

I was reading off the slides. The slide's after The Heart: Cardiac Output, then

the slides say Regulation of Heart Rate.

It has Increased heart rate: then sympathetic, hormones, exercise, decreased blood volume below it.

The next slide has Decreased heart rate, under it is decreased venous return.

Just trying to make sense in my brain!

Ignore my last post, GC's answer just popped up!!!

Thanks, GC. I didn't hear her say anything about the correction. My bad.

So know, why would high blood pressure or blood volume DECREASE output?

Doesn't make sense to me. The rest I get.

I'm reading and it's not all quite making sense but I think it has something to do with peripheral resistance on p. 388. Let's see if this makes sense... high blood pressure and volume would increase peripheral resistance which would make it harder for venous blood to be returned to the heart. So the cardiac output decreases to decrease blood volume and lower the blood pressure thus restoring homeostasis. That's the best I've got! :)

Ladies, Ladies.....It's saturday....Relax, go to the mall. Do something other than studying. Your brains will thank you. I learn more when I let my noggin have a day off and rest. Just a suggestion. If you feel the need then by all means cram till your hearts are content. Did you like the "heart" reference????:lol2:

but the book says on page 388, last sentence..Increased blood volume also raises peripheral resistance. Any factor that increases either cardiac output or peripheral resistance causes an almost immediate reflex RISE in blood pressure.
