Respiratory Acidosis And Alkalosis Made Easy

Share on facebook

Here I explain a bit about ABG"s or Arterial Blood Gases, and what values are normal, what values are abnormal, a chart to help you solve which type of compensation it is (metabolic or Respiratory), is it Acidosis or Alkalosis, and how much it may have compensated or not. Please open the charts in a second & 3 browser to reference, or open the normal range chart on google! At the end, I show easy tricks and ways on how to remember the chart, so you can recreate it for a nursing test, respiratory test, or Medical Laboratory science test, etc. Thanks for Watching!

Easy Way To Interpret Abg Values

ABG values can be very intimidating! Its hard to remember all the different normal values, what they mean, and which direction theyre supposed to be going. With so much information, its super easy to get mixed up and make a stupid mistake on an exam, even when you really DO know how to interpret ABGs. In this article, Im focusing more on the How to, rather than understanding whats going on with the A&P, which Ive already done in previous articles. If you want to understand whythese steps work (which you should do anyway to become a great nurse!),take some time to review my articles on Respiratory Imbalances and Metabolic Imbalances . Heres my 7-step method to interpreting ABGs. We have three puzzle pieces to put together: B)uncompensated, partially compensated, or compensated 1) Across the top of your page, write down the normal values for the three most important ABG lab results: pH (7.35-7.45), PaCO2 (35-45), and HCO3 (22-26). 2) Underneath pH, draw arrows to remind you which direction is acidic (down), and which direction is basic (down). 3) UnderneathPaCO2, and HCO3, draw arrows to remind you what abnormally high and low values would do to the bodys pH. When youre done, your p Continue reading >>

    There have been studies done on this, one done by Alperin et al. found the following results:
    In the upright posture, venous outflow is considerably less pulsatile (57%) and occurs predominantly through the vertebral plexus, while in the supine posture venous outflow occurs predominantly through the internal jugular veins. A slightly lower tCBF (12%), a considerably smaller CSF volume oscillating between the cranium and the spinal canal (48%), and a much larger ICC (2.8-fold) with a corresponding decrease in the MRI-derived ICP values were measured in the sitting position.

    Its all a play of the 'Gravity'.
    Veins in the legs are enveloped by the skeletal muscles there, and when they are actively contracting this squeezes the veins of its blood in a 'heart-ward' direction. You may ask why couldn't the blood flow the other way, thanks for the 'valves' that are interspersed along the length of this venous channel which prevents this from happening. This is the principle of 'the muscle pump' and it is important so much so that the soleus muscle (the main bulk of your calf) is called the 'second-heart' as it too literally pumps the blood.
    And now coming to what is that that causes the changes in cerebral perfusion with posture:
    [A word of caution: The cerebral perfusion is governed by auto-regulatory phenomenon, wherein the cerebral blood flow remains rather constant even with quite a change in blood pressure and a gross deviation from the normal of the blood pressure is needed to change it. And in fact, only in rare cases does this postural changes causes a syncope (Orthostatic hypotension) ,that too, with an added deficit of the sympathetic reflexes (reflex vasoconstriction)]

    In the supine position, since all of the body is at the same level, it is of the impression that there is no net differential effect of gravity on different parts of the body. And thus there is no active role of gravity in deciding the blood flow, and the other factors which control blood flow comes to play.

    While in standing position and that too in a 'static stance' for long, due to gravity, the blood (venous) pools in the lower limbs, and thus there is less blood that reaches the heart (less venous return) and consequently heart pumps less blood as whatever heart does is just pump the quantity it has been filled before systole (preload). There is a decrease in blood pressure and thus a 'relatively' decreased blood perfusion. As I mentioned earlier too, there are regulatory mechanisms that maintains a constant cerebral perfusion in the face of a changing blood pressure. As the fMRI is quite sensitive a test, it can rather be that it does recognise this slight 'relative' change of the flow. But surely, the transient fall in BP, can be recorded, though this transient fall is quickly compensated by sympathetic activation.
    Its an accepted fact that in cases of orthostatic hypotension, the syncope (caused by cerebral hypoperfusion) is caused in patients of a sympathetic defecit (or decreased activity) when in the standing posture, where the decreased blood pressure remains uncompensated and a fall in BP below a critical level does with a decrease in cerebral perfusion for a few seconds and due to this hypoxic condition syncope occurs. And ironically, when the person falls of syncope, the gravity component is canceled and he regains his consciousness due to corrected cerbral flow, thus this can too be taken as a proof of the effect of posture on cerebral perfusion.

10 arterial blood gas problems worked using the tic-tac-toe method.

8-step Guide To Abg Analysis: Tic-tac-toe Method

An arterial blood gas (ABG) is a blood test that measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood . Blood for an ABG test is taken from an artery whereas most other blood tests are done on a sample of blood taken from a vein. This test is done to monitor several conditions that can cause serious health complications especially to critically ill individuals. Every day, a lot of nursing and medical students assigned in acute areas encounter ABG results, which they may not necessarily be able to interpret with its knotty aspect. They struggle over the interpretation of its measurements, but they are not especially complicated nor difficult if you understand the basic physiology and have a step by step process to analyze and interpret them. There may be various tips and strategies to guide you, from mnemonics, to charts, to lectures, to practice, but this article will tell you how to interpret ABGs in the easiest possible way. And once you have finished reading this, youll be doing actual ABG analysis in the NCLEX with fun and excitement! Here are the steps: Know the normal and abnormal ABG values when you review the lab reports. Theyre fairly easy to Continue reading >>

    > When do you start to lose weight only after you are in ketosis?

    Hi,
    It took me 5 days to get into ketosis (waaaay longer than I anticipated). I'm assuming I had a lot of built up carbs in my system before I started on my diet. I haven't lost any weight. In fact, I've gained 3 lbs! I'm wondering if the weight will start to come off now that I'm in ketosis. Is that when it begins? Also, I am really starving without the carbs, so I'm eating a lot more than I usually would. Can I be gaining weight from this diet??
    Thanks!

    Don't Panic!!
    It entirely depends not only on how much you are eating, but what type of food whether or not you could gain weight.
    I notice that anything high in salt makes me retain water. Cheese, cured meats, salted pork rinds, pickles. These are Atkins friendly and will not hinder ketosis per se, but may cause you to retain water. Think back over the last 5 days and remember if you have eaten these foods or anything else, such as broth which may be high in salt.( Read labels for hidden salt/sodium.)If so, you may be losing fat while retaining water and it could register on the scale as a gain. When you stop eating the hidden salt, it may be a day or two before you experience your body flushing all that extra water quickly and then finally your scale will show a loss.
    Another common error is relying a lot on artificially sweetened products, which a lot of LCers have noticed can stall their weight loss. Diet soda is notorious, so are Atkins bars. Not everybody has a problem with these things, but you may find out that you do.
    Those are just the possibilities that come to my mind, I'm sure other seasoned LCers can think of other things. Don't ditch the diet, you've barely started and there are bound to be setbacks along the way.
    Meanwhile, if you are extra hungry, perhaps you could post an example of a day or two of your menu so some of the more sophisticated LCers can help you spot trouble?
    Good luck!

    Low carb diets will not cause you to lose weight unless you are overweight. Do you consider yourself overweight? Nevertheless they will make you much healthier.

    > Pregnancy - Ketosis - WHY NOT??

    Why is ketosis bad for pregnancy?? I am hoping to start the longest thread on here and pick brains of all you mommas havin' bebes. :)
    I currently have lost 33 pounds in the past 11 weeks on this wonderful WOE and after the next 30 pounds we are going to try and conceive our third and final baby.
    Problem? I might be pregnant right now... :( lol (which is fine, we're ready)
    Question? Why are 'ketones' bad for the baby??? I have read and read and read and read every single article, website, and post about pregnancy and ketosis.... the end result all I know is "Tsk tsk tsk.. stay out of ketosis... and up carbs so you're not spilling ketones...."
    WHY???? NO ONE HAS SAID WHY??
    Yes, I think I came across ONE study where some children were tested at kindergarten age and the ones whose mother's were in ketosis while carrying had lower test scores... in KINDERGARTEN!
    This was not a low carb study, but rather a study on starvation.
    Were these mothers following a HEALTHY low carb diet? NO
    Were they in monitored ketosis on purpose? Probably not
    Could they have been smoking crack and that's why they weren't eating right? Yes (it said nothing like that was controlled)
    Are pregnant women that are NOT low carbing in ketosis OFTEN during pregnancy anyway?? YES, during morning sickness when they can't hold anything down. I'm sure they are.
    And, then there's the Eskimos... I have read, too, that they are constantly in ketosis and using protein and fat for fuel because they have NO carbs where they are.... are Eskimoe babies brain damaged?? I should think not.
    WHEW, can you tell I'm frustrated?? I just want someone to say "HEY, I was in ketosis and HERE"s what happened to my poor child" and then I won't even consider it, but no one is there to say that.
    AAAARGH, please, help !
    Thanks a ton,
    Kitten

    Not a doctor, but I was just pregnant. ;)
    I don't think it's the ketosis itself so much as the fact that, while you're in ketosis, you're burning off fat and losing weight. Pregnancy is not the time to be losing weight. Even very overweight people are still advised to gain while pregnant (although they are told to keep the gain down, like 15 lbs. instead of the average 25-35). Your baby needs your fat stores. The baby also needs you to eat a healthy, nutrient-rich, varied diet. It seems to me that Atkins maintenance (with maybe a few added things like milk) would be perfect for this.
    I ate like a pig in an ice cream shop for most of my pregnancy. I tried to eat "healthy" foods, but I didn't stop myself from eating a bunch of crap as well. I gained 42 lbs. My doctor told me that the pregnancy itself (baby, extra blood, extra breast tissue, etc.) weighs 26 lbs. on average. Anything you gain on top of that is just fat. Sure enough, I lost exactly 26 lbs. practically in the delivery room (okay, it was really within 3 weeks of birth). Now I'm here to take care of the rest.
    I'm telling you this because I'd wager that if you followed a maintenance-level, healthy low-carb plan during your pregnancy your gain would be right around 26 lbs. That would make your post-partum rebound much easier than most people's.
    My $0.02, sorry if it was too long. :)

  3. KittenSynn

    Yes, I agree with everything you have said, thank you. But, I was 190 when I got pregnant with my last son and my doctor DID tell me to NOT gain any weight!!! Not even the 26 lbs. So, essentially he was telling me to lose weight... because after delivery I would have been less.
    To his dismay I gained 14 lbs... (I only gained 15 with my first child) and lost it immediately after the pregnancy. I gained all of my weight (a hefty 253) eating constantly AFTER the birth of both of my children :cry: . I didn't find this WOL until 11 weeks ago.
    I am genuinely thinking that my diet now is WAY healthier (with supplements) than most pregnant women not on this WOL eat.
    I would still love to hear answers to my specific "What happens if" questions. I ALSO WANNA HEAR FROM ALL YOU MOMMAS WHO STAYED IN KETOSIS... I KNOW YOU'RE OUT THERE! LOL
    Thanks for your .02 cents though! :)
