Alkalosis is the result of a process reducing hydrogen ion concentration of arterial blood plasma (alkalemia). In contrast to acidemia (serum pH 7.35 or lower), alkalemia occurs when the serum pH is higher than normal (7.45 or higher). Alkalosis is usually divided into the categories of respiratory alkalosis and metabolic alkalosis or a combined respiratory/metabolic alkalosis. Respiratory alkalosis is caused by hyperventilation, resulting in a loss of carbon dioxide. Compensatory mechanisms for this would include increased dissociation of the carbonic acid buffering intermediate into hydrogen ions, and the related excretion of bicarbonate, both of which lower blood pH. Hyperventilation-induced alkalosis can be seen in several deadly central nervous system diseases such as strokes or Rett syndrome. Metabolic alkalosis can be caused by rep
Bases: Have a higher affinity for protons than water and easily acquire protons in aqueous solution. charged (+1) when protonated (Acids uncharged) uncharged when de-protonated (Acids -1 charge) Most common biological weak base is the amino group, -NH2 Despite the differences between acids and bases the pKa concept can be used to quantitate the relative strength of amino groups. Notice: pKa values for carboxylic acid are less than < 7, pka values for amino groups are >7 (usually 9-11) i.e. a simple biologically important 10 amine, ethanolamine, pKa = 9.5 or choline, a quaternary (40) amine, pKa = 13.9 Choline is a good compound for systems in which a permanent positive charge is desirable, i.e. membranes (hydrophilic head groups) Phosphatidylcholine (lecithin) a key amphiphilic compound in biological membranes Buffering: At or near their pKa both weak acids and weak bases will resist changes in pH, thus acting as buffers Buffering is very important in biological systems, for rapid pH changes have disastrous consequences. The buffering capacity of ethanolamine and acetic acid occur well outside of the pH range normally seen in human blood (pH 7.35-7.45). Thus, other ionizable compou

Blood Gas Analysis, Pt 5: Metabolic Acidosis And Alkalosis
Base excess (BE) and bicarbonate (HCO3-) represent the metabolic components of the acid base equation. In general, both components will change in the same direction. Decreased HCO3– and BE indicate either a primary metabolic acidosis or a metabolic compensation for a chronic respiratory alkalosis. Elevated HCO3– and BE indicate either a primary metabolic alkalosis or a metabolic compensation for a chronic respiratory acidosis. The exception to this rule arises when a patient hypoventilates or hyperventilates. Carbonic acid equation CO2 + H2O ↔ H2CO3 ↔ HCO3– + H+ When a patient hypoventilates, CO2 will increase as a result of reduced expiration, so a shift to the right of the equilibrium will occur. The shift to the right will increase the bicarbonate levels proportional to the increase in CO2. The opposite occurs when a patient hyperventilates; the equilibrium shifts to the left, so a decrease in HCO3– is present. Since HCO3– is not independent to the patient’s respiratory status, it is an inaccurate way of measuring the metabolic component in patients with respiratory changes. For this reason, the BE value is the preferred. The BE represents the amount of acid, or
In this video I discuss why does the body need calcium, how much calcium does the body need, and what does calcium do in the body. Transcript Calcium is a macro mineral and is the most abundant mineral in the human body. Its functions include the mineralization of bones and teeth, it also helps in nerve functioning, and assists in the contraction and relaxation of muscles. It also help in regulating blood pressure, blood clotting, and overall immune system health. Food sources of calcium include cow’s milk products, small fish with bones such as salmon, green leafy vegetables, and legumes. since most people do not consume enough calcium consumption can be a concern. Calcium consumption is a concern since most people do not consume enough. Calcium deficiency can cause reduced bones mass and strength in children and it can lead to ostemalacia, osteopenia, and osteoporosis in adults. The recommended daily intake for calcium for men and women is 1000 mg per day. Toxicity can occur as low as 2.5 g per day depending on the individual. Side effects at high doses include nausea, vomiting, kidney damage, and irregular heart rhythm.
Laboratory Investigation Effects Of Metabolic Acidosis And Alkalosis On Sodium And Calcium Transport In The Dog Kidney
Effects of metabolic acidosis and alkalosis on sodium and calcium transport in the dog kidney. Clearance and micropuncture studies have been performed in dogs to examine the effects of acute and chronic metabolic acidosis and acute alkalosis on tubular sodium and calcium transport. Acute metabolic acidosis, induced by the infusion of hydrochloric acid, decreased proximal fluid reabsorption and increased the fractional delivery of sodium and calcium to the distal tubule, but not to the final urine. In comparison with normal dogs, dogs with chronic metabolic acidosis (induced by feeding ammonium chloride) showed an increase in proximal fluid reabsorption and a dissociation of calcium from sodium reabsorption more distally, leading to an increased delivery of calcium relative to sodium at the distal tubule and in the final urine. The infusion of sodium bicarbonate to correct chronic metabolic acidosis, both in intact and thyroparathyroidectomized (TPTX) dogs, reduced proximal fluid reabsorption and caused a selective enhancement of calcium reabsorption relative to sodium in the more distal nephron, resulting in a reversal of the dissociation observed in acidosis, both at the distal tu

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 article ...
The kidneys and lungs maintain the balance (proper pH level) of chemicals called acids and bases in the body. Acidosis occurs when acid builds up or when bicarbonate (a base) is lost. Acidosis is classified as either respiratory or metabolic acidosis. Respiratory acidosis develops when there is too much carbon dioxide (an acid) in the body. This type of acidosis is usually caused when the body is unable to remove enough carbon dioxide through bre ...
