Renal Compensation

Chronic Carbon Dioxide Retainer Renal compensation of respiratory acidosis is by increased urinary excretion of hydrogen ions and resorption of HCO3−. This relatively slow process occurs over several days. Slowly, pH reaches low normal values, but HCO3− levels and BE are increased. This is the situation of the patient with chronic respiratory failure. Pulmonary patients usually have chronic obstructive pulmonary disease or restrictive pulmonary disease, or they are morbidly obese. Increased Co2 stores are the rule, and the normal respiratory drive to Paco2 is obtunded. This group of patients is sensitive to O2 supplementation because respiratory drive is predominantly determined by hypoxemia. Patients with a Pao2 in the mid-50s and a Paco2 at the same level usually receive home O2 treatment, initially at night to reduce pulmonary hypertension and to relieve dyspnea. When the chronic Co2 retainer develops an acute respiratory problem and pH levels fall to less than 7.20, noninvasive ventilatory assistance is usually indicated. Fetoplacental Elimination of Metabolic Acid Load Fetal respiratory and renal compensation in response to changes in fetal pH is limited by the level of ma Continue reading >>

    What are hyperkalemia and metabolic acidosis?




    1 Answer







    Hyperkalemia = high potassium levels in the blood. Commonly due to renal failure- kidneys not able to get rid of potassium so it builds up in your body. Hyperkalemia can be fatal because it causes heart arrhythmias including ventricular fibrillation.

    Metabolic acidosis is also a result of renal failure and is due to the kidneys not being able to excrete enough acid. Normally the pH of your blood is 7.35–7.45, so anything below 7.35 is considered ‘acidosis'. Metabolic in this case simply means caused by the kidneys, as opposed to ‘respiratory' acidosis which is due to airway obstruction and not being able to breathe out enough CO2

What is SERUM ALBUMIN? What does SERUM ALBUMIN mean? SERUM ALBUMIN meaning, definition & explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Serum albumin, often referred to simply as blood albumin, is an albumin (a type of globular protein) found in vertebrate blood. Human serum albumin is encoded by the ALB gene. Other mammalian forms, such as bovine serum albumin, are chemically similar. Serum albumin is produced by the liver, occurs dissolved in blood plasma and is the most abundant blood protein in mammals. Albumin is essential for maintaining the oncotic pressure needed for proper distribution of body fluids between blood vessels and body tissues; without albumin, the high pressure in the blood vessels would force more fluids out into the tissues. It also acts as a plasma carrier by non-specifically binding several hydrophobic steroid hormones and as a transport protein for hemin and fatty acids. Too much or too little circulating serum albumin may be harmful. Albumin in the urine usually denotes the presence of kidney disease. Occasionally albumin appears in the urine of normal persons following long standing (postural albuminuria). Albumin functions primarily as a carrier protein for steroids, fatty acids, and thyroid hormones in the blood and plays a major role in stabilizing extracellular fluid volume by contributing to oncotic pressure (known also as colloid osmotic pressure) of plasma. Because smaller animals (for example rats) function at a lower blood pressure, they need less oncotic pressure to balance this, and thus need less albumin to maintain proper fluid distribution. Albumin is synthesized in the liver as preproalbumin which has an N-terminal peptide that is removed before the nascent protein is released from the rough endoplasmic reticulum. The product, proalbumin, is in turn cleaved in the Golgi vesicles to produce the secreted albumin.

Payperview: Serum Potassium Concentration In Acidemic States - Karger Publishers

Serum Potassium Concentration in Acidemic States I have read the Karger Terms and Conditions and agree. It has been generally accepted that acidosis results in hyperkalemia because of shifts of potassium from the intracellular to the extracellular compartment. There is ample clinical and experimental evidence, however, to support the conclusion that uncomplicated organic acidemias do not produce hyperkalemia. In acidosis associated with mineral acids (respiratory acidosis, end-stage uremic acidosis, NH4CI- or CaCl2-induced acidosis), acidemia per se, results in predictable increases in serum potassium concentration. In acidosis associated with nonmineral organic acids (diabetic and alcoholic acidosis, lactic acidosis, methanol and the less common forms of organic acidemias secondary to methylmalonic and isovaleric acids, and ethylene glycol, paraldehyde and salicylate intoxications), serum potassium concentration usually remains within the normal range in uncomplicated cases. A number of factors, however, may be responsible for hyperkalemia in some of these patients other than the acidemia per se. These include dehydration and renal hypoperfusion, preexisting renal disease, hyperc Continue reading >>

Effects Of Ph On Potassium: New Explanations For Old Observations

Go to: Abstract Maintenance of extracellular K+ concentration within a narrow range is vital for numerous cell functions, particularly electrical excitability of heart and muscle. Potassium homeostasis during intermittent ingestion of K+ involves rapid redistribution of K+ into the intracellular space to minimize increases in extracellular K+ concentration, and ultimate elimination of the K+ load by renal excretion. Recent years have seen great progress in identifying the transporters and channels involved in renal and extrarenal K+ homeostasis. Here we apply these advances in molecular physiology to understand how acid-base disturbances affect serum potassium. The effects of acid-base balance on serum potassium are well known.1 Maintenance of extracellular K+ concentration within a narrow range is vital for numerous cell functions, particularly electrical excitability of heart and muscle.2 However, maintenance of normal extracellular K+ (3.5 to 5 mEq/L) is under two potential threats. First, as illustrated in Figure 1, because some 98% of the total body content of K+ resides within cells, predominantly skeletal muscle, small acute shifts of intracellular K+ into or out of the extr Continue reading >>

  • Respiratory Acidosis Vs Metabolic Acidosis

    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 ...

    The notion that acid-base and potassium homeostasis are linked is well known. Students of laboratory medicine will learn that in general acidemia (reduced blood pH) is associated with increased plasma potassium concentration (hyperkalemia), whilst alkalemia (increased blood pH) is associated with reduced plasma potassium concentration (hypokalemia). A frequently cited mechanism for these findings is that acidosis causes potassium to move from cel ...
