Acid-Base Case study 1
The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide concentration decides respiratory alkalosis or respiratory acidosis. Normally arterial blood gas analysis are used to assess the acid-base balance.
Upon systematic reviewing of the given case study it is noted that the PaO2 and PaCO2 are within normal limits, indicates that patient is not hypoxemic, still need to continue monitoring of oxygen saturation. The increased pH level of 7.5 indicates alkalosis. The next step is to evaluate PaCO2.Since lung regulates this, its

Another treatment plan for metabolic alkalosis is by replacement of electrolytes, plasma volume. , histamine -2 receptor blockers to prevent further gastric acid loss severe case alkalosis can be corrected by dilute (0.1 N) hydrochloric acid or ammonium chloride, mechanical hypoventilation, low acetic acid hemodialysis. Supportive measures include provision of oxygen, monitoring and observation for further development of complication such as depression of ventilation and myocardial perfusion

    When they are functioning normally, the kidneys eliminate toxins, metabolic wastes, and excess ions, while they retain substances useful to the body. The urinary system rids the body of these wastes. The urinary system is also involved in maintaining proper blood volume, blood pressure and ion absorption within the blood. The kidneys produce erythropoietin, a hormone that stimulates red blood cell production. The kidneys also maintain the correct water content of the body and the correct salt composition of extracellular fluid.…

    Blood is an instance of a naturally buffered answer. Blood should preserve a pH close to 7.four so one can convey oxygen successfully and includes compounds that react to acids or bases so that it will neutralize them. procedures that take place in residing organisms are called physiological techniques. Like blood circulatory machine, breathing and so forth. The inner pH of maximum dwelling cells is near 7.zero.…

    The pH is sensed by the central and peripheral chemoreceptors and integrated by the medulla which causes appropriate action by controlling the respiratory rate and volume. Acidosis causes hyperventilation causing the release of CO2 and hence the volatile acid H2CO3 normalizing the pH. Alkalosis causes hypoventilation and retention of CO2 and hence doesn’t allow the pH to rise. RENAL COMPENSATION Kidneys play an important role in the long term regulation of pH. It does so by regulating acid excretion, bicarbonate reabsorption, H+ secretion and ammonium ion…

    This is when hydrochloric acid (HCL) is reduced in the stomach and the body tries to compensate by releasing aldosterone and then reabsorbs HCO3 into the blood (Lewis, 2016). If the condition is not treated the respiratory and renal systems will try to compensate for the acid-base…

    The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This equation can also be reversed; it is a chemical equilibrium. If the hydrogen ions rise, bicarbonate accepts the hydrogen ions and the equilibrium shifts left thus making the blood acidic.…

    But because they contain a lot of energy, amino acids are transported to the liver where they get the toxic amino acid group removed via deamination. The amino acid then forms the very soluble but highly toxic ammonium before being converted to urea and is then transported to the liver for excretion. There is some remaining keto acid which can be respired or converted to a carbohydrate or fat for storage. c. Describe the histology and gross structure of the liver Hepatic artery Supplies the liver with oxygenated blood from the heart. The oxygen supplied is need for aerobic respiration.…

    This may occur for many different reasons, including dehydration and use of certain medications (Division of Oral Medicine and Dentistry, n.d. para. 3). One result of hyposalivation is a reduced output of enzymes and hence a lack of hydrolysis. This spiraling issue may inhibit the digestion of carbohydrates at the very beginning of the gastrointestinal tract (Whitney & Rolfes, 2013, p. 74). One method to prevent or reverse hyposalivation is proper fluid intake as noted…

    Prophylactic hemin is a porphyrin chelate of iron, derived from red blood cells. Panhematin® is one of many prescribed medications for the treatment of acute intermittent porphyria attacks. Hemin is administered to avoid the progression of generalized pain to a neurological crisis. Because delta-aminolevulinic acid, the first step in heme synthesis, is regulated by a heme feedback mechanism, it was determined that acute porphyrias represent a deficiency in hepatocytes (Bissell & Wang, 2015). Hemin helps reduce 5’-aminolevulinate synthase-1 activity allowing the liver to reduce production of delta-aminolevulinic acid and porphobilinogen (Besur, Hou, Schmeltzer, & Bonkovsky,.…

    Keeping our body’s pH balance in check is always important this because proper body function can happen and we remain healthy. If your blood pH were to drop below 7.35 you would develop a condition called acidosis. Then depending on the cause of this acidosis whether it be the kidneys or the lungs would determine the kind of acidosis. If it is the kidneys causing the acidosis we would call it a metabolic acidosis, where is if it were the lungs it would be called a respiratory acidosis. Know if your blood pH for some reason would be above 7.35 you would be considered alkalosis.…
