    I'm sure you need just one more thing to read on this!!! This is not out of my brain, that's why it may make sense!!:chuckle

    Preload is what comes to the heart before contraction. The heart muscle is much like a rubber band. The more you stretch it, the better it will contract. This stretch is accomplished in the heart through filling of the ventricles with blood. Therefore, preload is related to the amount of blood in the ventricle before contraction. If a person is overhydrated, preload will increase. If a person is dehydrated, preload will decrease.
    Afterload is what comes after ventricular contraction or the resistance against which the heart must pump blood. Afterload is determined by two conditions; the blood volume ejected from the ventricle and the compliance of the vascular space into which the blood is ejected. Think of afterload as a hose nozzle. If the hose nozzle is wide open, afterload is decreased due to decreased compliance. If the hose nozzle is almost closed, afterload will increase because the water has so much resistance to push against. Now, if you increase or decrease the amount of water that comes from the nozzle, there will be a further effect on the afterload. Think of afterload as blood pressure. Increased blood pressure is increased afterload, while decreased blood pressure is decreased afterload.

    Ugh, I just typed this long reply and hit the "leave a comment" button on the bottom right. Wrong button.
    I took my training from someone who lives in No. Cal. and she has been a foot care nurse for 17+ years, mostly on her own. Hopefully someone from cali will chime in here and give you particulars since I wouldn't want you to rely on my info.
    I live in Idaho and I work within my scope according to our BON. I am providing for activities of daily living, for which I was taught to do in my general nursing education and I have gained further education to provide for this specialty. I have my own clinic (still working on an opening date though) and provide home care. My business isn't completely off the ground yet, but I expect some problems with Dr.'s questioning my scope. I'm prepared. I want to work along side them, not against them, so we will see how it goes when I go out and market myself to other Dr.'s and podiatrists. That will be a big test. I need pods to refer to though, so hopefully they will accept this nursing venture and come to realize that it is the way of the future!!!
    I highly recommend that you get your CFCN and save up to buy the appropriate tools/instruments. If we want to be taken seriously, we must be as professional as we would expect someone to be for us. Most pods don't even use the podiatry drill that I purchased. They use a dremel which is really not appropriate for health care. I give my clients the best of the best. I have nothing to hide! Good equipment, good instruments (well...those could be better but man nippers are expensive), and good products. People love nurses!
