ABGs interpretation & Acid base imbalances Made Easy for Nursing students NCLEX

video okay let's get into it we're going to be covering the basic overview in this part one including pathophysiology and memory tricks and then we're going to break down some practice questions toward the end of this video including the really tricky fully compensated versus partially compensated abgs so be sure to stick around so what are acidbase imbalances well it's just the balance of acid and base of the body kind of like a tug ofwar the body loves to keep these in Balance measured in blood via the pH so normal pH is 7.35 to 7.45 too low under 7.35 we become acid basically the body goes into acidosis and too high over 7.45 we become more base the body goes into alkalosis now that sounds pretty simple right well here's where it gets confusing the key players that keep us in balance is hc3 known as bicarb this is our base that helps to put the body in this alkalosis so the memory trick think of the double B's base equals bicarb and CO2 or carbon dioxide is our acid pushing the body into an acidotic state so too much CO2 we get a body that is in acidosis so the memory trick we use just think carbon dioxide is carbon di acid Aid since too much carbon dioxide pushes us into acidosis lastly hydrogen ions are a form of Acid found in the stomach acids as well as urine so the memory trick just think hydrogen ions is high acid too much hydrogen ions equals an acidotic State now simply organize this in your mind what makes the body acidotic well hydrogen ions get high acid Aid and carbon dioxide just think carbon di acid and for base which makes us alkalotic just think byic carb base now the main organs that control these are the lungs and the kidneys so the lungs control carbon dioxide that CO2 we breathe in oxygen and breathe out ah that CO2 normal gas exchange right so just like you heard the main way to get Co2 out of the body is by exhaling so the less you breathe out well the less CO2 comes out and so more CO2 is retained in the body which makes the body more acidic so remember more carbon dioxide means more carbon di acid a very acidotic body so naturally decrease in respiratory rate we have more acid from more CO2 now we see this in patients who are intoxicated or overdosed or even even a head injury we have low respiratory rate so CO2 is higher in the body and with increased respiratory rate we have less acid that less CO2 like with hyperventilation from an anxiety attack we breathe out all that CO2 so the body becomes less acidic and more alkalic that base now on the other side of things the kidneys control two key players here hydrogen ions and by carb H3 the kidneys regulate this acid base imbalance by excreting more acid into the urine and retaining more base bicarb kind of like a teeter totter or a seesaw here so in the same big video thank you guys so much for watching please be sure to download your cheat sheet study guides as well as take the quiz on the membership sites and please be sure to share with your classmates and instructors thanks so much for watching in
