Acidosis is a biological process producing hydrogen ions and increasing their concentration in blood or body fluids. pH is the negative log of hydrogen ion concentration and so it is decreased by a process of acidosis.
Metabolic acidosis can lead to acidemia, which is defined as arterial blood pH that is lower than 7.35. [6] Acidemia and acidosis are not mutually exclusive – pH and hydrogen ion concentrations also depend on the coexistence of other acid-base disorders; therefore, pH levels in people with metabolic acidosis can range from low to high.
Lactic acidosis refers to the process leading to the production of lactate by anaerobic metabolism. It increases hydrogen ion concentration tending to the state of acidemia or low pH . The result can be detected with high levels of lactate and low levels of bicarbonate .
Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO − 3), or alternatively a direct result of increased bicarbonate concentrations.
Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine. [1] In renal physiology, when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron, allowing for exchange of salts, acid equivalents, and other solutes before it drains into the bladder as urine.
The converse happens if the pH in the ECF tends to rise: bicarbonate ions are then excreted into the urine and hydrogen ions into the blood plasma. The second and third lines of defense operate by making changes to the buffers, each of which consists of two components: a weak acid and its conjugate base .
An acidosis is a physiologic process that increases hydrogen ion concentration. An alkalosis is a physiologic process that decreases hydrogen ion concentration. [ 15 ] [ 16 ]
Metabolic acidosis can cause hyperkalemia as the elevated hydrogen ions in the cells can displace potassium, causing the potassium ions to leave the cell and enter the bloodstream. However, in respiratory acidosis or organic acidosis such as lactic acidosis , the effect on serum potassium are much less significant although the mechanisms are ...
