Peripheral Neuropathy Pain Symptoms Relieved Davis
We've been managing you here for peripheralneuropathy in lower legs and feet. When you first presented to the office you indicatedthat the pain was very bad, very numb, very tingling. How are you doing today, and howare you responding to the neuropathy program here in our office? Oh gosh, it's much better.I feel that I can walk, before I couldn't get out of bed in the morning I had to holdon to something and I just get up and walk, I can still the numbness on the bottom ofmy foot, but and then walking in this door I don't get as tired as I did before. I usuallyhave to go home and change shoes. I get home and I can keep the shoes on for quite a while.I haven't yet started walking on the street,
but I will. So far so good right? Yea, whata difference. Well congratulations on your results thus far I'm very happy with yourprogress. Thank you.
Hydrostatic vs Oncotic Pressure Osmosis albumin fluid management edema
Created by nurses, for nurses.Are you ready to take your learning to the next level? Sit back and crank up the volume.Here s your host, Jon Haws. Okay, everybody, welcome to another episodeof NRSNG . My name is Jon. I m a intensive care nurse and at the Level I Trauma Centerin Dallas, Texas. Today, I wanted to talk about Hydrostatic vs Oncotic Pressure. Thisis gonna be a little bit confusing for people I remember in nursing school having a hardtime understanding it and kinda getting a grasp for this. It is has really helped understandpressures and things a bit more. So, before I start, I kinda let you know that if yougo to OncoticPressure , you ll be able
to download this entire presentation in PDFform so you can have it for notes, and to make your notes on, and to remember everythingthat you ve learned. You can also get it on NRSNG Freebies. So, either one ofthose, you ll be able to get this presentation and make your notes. Okay. So, when we start trying to understand thedifference between hydrostatic and oncotic pressure, first of all, we have to understandwhat osmosis is. Now, we probably learned about osmosis in our Bio 101 class and enteredin chemistry, but basically, what osmosis is, is it s really the passage of liquid througha semipermeable membrane from an area of low
concentration to an area of high concentrationof solute. So, basically, what we have is, we have our liquid here, and inside our liquid,we have a bunch of solutes. Okay, there s all of our solutes. And between that, we havea semipermeable membrane which means that fluid can pass but things of specific sizeare not able to pass. So, liquid can pass through but these little solutes can t passthrough that membrane. So, what s the liquid going to do, is it s going to pass throughthis membrane until homeostasis is reached; until the concentration of the solute is equalon either side of that membrane. So, that s what osmosis is. That s an important conceptto understand. So, basically it is the passage
of liquid from an area of low concentrationof solute to an area of high concentration of solute to achieve equilibrium and equalconcentration of that solute of that solute on either side of that semipermeable membrane. Okay, so what is Oncotic Pressure? This definitioncomes from Wikipedia where it says that Oncotic Pressure, or colloid osmotic pressure, isa form of osmotic pressure exerted by proteins, notably albumin, in a blood vessel s plasmathat usually tends to pull water into the circulatory system. Okay, so, what does thatmean? Okay, so first of all, what is a colloid? Okay, if we go back to that previous slidethere, we saw that a colloid, a colloid is
essentially, it s a substance that does notdiffuse easily across a semipermeable membrane. So, as we saw there, in that previous slide,so all these little solutes in here, those are gonna be referred to as colloids. So,they are not gonna perfuse across this membrane. And so, that s what we re talking about whenwe re talking about our colloids. Okay. So then, what again is Oncotic Pressure? Basically,it s the pressure that those colloids (proteins like Albumin within the blood) exert to drawwater into the capillary system. Okay, so we have our capillary system, and what oncoticpressure is within our capillary system, we have proteins like albumin. Okay, and albuminis a large protein, and it s not going to
be able to get out of the capillary systemunder normal circumstances. So, what s gonna happen is, we have all these albumin in here,and we have all these fluid outside the capillary system. And what that albumin is going todo is, it s going to exert a pressure or force to draw fluid into our capillary system. So,that s why it s called Colloid osmotic pressure, it is the osmotic pressure that these colloidsare exerting within the capillaries to draw fluids inside the capillary system. So, albuminis gonna be the one that we really focus on within the body because it s going to be oneof the, it s gonna be the one that exerts most the pressure. It s a very large proteinwithin the capillary system. Okay.
