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 breathing. Other names for respiratory acidosis are hypercapnic acidosis and carbon dioxide acidosis. Causes of respiratory acidosis include: Chest deformities, such as kyphosis Chest injuries Chest muscle weakness Chronic lung disease Overuse of sedative drugs Metabolic acidosis develops when too much acid is produced in the body. It can also occur when the kidneys cannot remove enough acid from the body. There are several types of metabolic acidosis: Diabetic acidosis (also called diabetic ketoacidosis and DKA) develops when substances called ketone bodies (which are acidic) build up during uncontrolled diabetes. Hyperchloremic acidosis is caused by the loss of too much sodium bicarbonate from the body, which can happen with severe diarrhea. Poisoning by aspirin, ethylene glycol (found in antifreeze), or methanol Lactic acidosis is a buildup of lactic acid. Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. This can be caused by: Cancer Drinking too much alcohol Exercising vigorously for a very long time Liver failure Low blood sugar (hypoglycemia) Medications, such as salicylates MELAS (a very rare genetic mitochondrial disorder that affects energy production) Prolonged lack of oxygen from shock, heart failure, or seve Continue reading >>
Acidosis is a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis (a condition in which there is too much base in the body fluids).

What is metabolic acidosis? The buildup of acid in the body due to kidney disease or kidney failure is called metabolic acidosis. When your body fluids contain too much acid, it means that your body is either not getting rid of enough acid, is making too much acid, or cannot balance the acid in your body. What causes metabolic acidosis? Healthy kidneys have many jobs. One of these jobs is to keep the right balance of acids in the body. The kidneys do this by removing acid from the body through urine. Metabolic acidosis is caused by a build-up of too many acids in the blood. This happens when your kidneys are unable to adequately remove the acid from your blood. What are the signs and symptoms? Not everyone will have signs or symptoms. However, you may experience: Long and deep breaths Fast heartbeat Headache and/or confusion Weakness Feeling very tired Vomiting and/or feeling sick to your stomach (nausea) Loss of appetite If you experience any of these, it is important to let your healthcare provider know immediately. What are the complications of metabolic acidosis if I have kidney disease or kidney failure? Increased bone loss (osteoporosis): Metabolic acidosis can lead to a loss of bone in your body. This can lead to a higher chance of fractures in important bones like your hips or backbone. Progression of kidney disease: Metabolic acidosis can make your kidney disease worse. Exactly how this happens is not clear. As acid builds up, kidney function lowers; and as kidney function lowers, acid builds up. This can lead to the progression of kidney disease. Muscle loss: Albumin is an important protein in your body that helps build and keep muscles healthy. Metabolic acidosis lowers the amount of albumin created in your body, and leads to muscle loss, or what is called ā Continue reading >>

Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body. If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than 7.35) due to increased production of hydrogen ions by the body or the inability of the body to form bicarbonate (HCO3ā) in the kidney. Its causes are diverse, and its consequences can be serious, including coma and death. Together with respiratory acidosis, it is one of the two general causes of acidemia. Terminology : Acidosis refers to a process that causes a low pH in blood and tissues. Acidemia refers specifically to a low pH in the blood. In most cases, acidosis occurs first for reasons explained below. Free hydrogen ions then diffuse into the blood, lowering the pH. Arterial blood gas analysis detects acidemia (pH lower than 7.35). When acidemia is present, acidosis is presumed. Signs and symptoms Symptoms are not specific, and diagnosis can be difficult unless the patient presents with clear indications for arterial blood gas sampling. Symptoms may include chest pain, palpitations, headache, altered mental status such as severe anxiety due to hypoxia, decreased visual acuity, nausea, vomiting, abdominal pain, altered appetite and weight gain, muscle weakness, bone pain, and joint pain. Those in metabolic acidosis may exhibit deep, rapid breathing called Kussmaul respirations which is classically associated with diabetic ketoacidosis. Rapid deep breaths increase the amount of carbon dioxide exhaled, thus lowering the serum carbon dioxide levels, resulting in some degree of compensation. Overcompensation via respiratory alkalosis to form an alkalemia does not occur. Extreme acidemia leads to neurological and cardia Continue reading >>
26.5 Disorders Of Acid-base Balance
Chapter 26. Fluid, Electrolyte, and Acid-Base Balance By the end of this section, you will be able to: Identify the three blood variables considered when making a diagnosis of acidosis or alkalosis Identify the source of compensation for blood pH problems of a respiratory origin Identify the source of compensation for blood pH problems of a metabolic/renal origin Normal arterial blood pH is restricted to a very narrow range of 7.35 to 7.45. A person who has a blood pH below 7.35 is considered to be in acidosis (actually, physiological acidosis, because blood is not truly acidic until its pH drops below 7), and a continuous blood pH below 7.0 can be fatal. Acidosis has several symptoms, including headache and confusion, and the individual can become lethargic and easily fatigued ( Figure 1 ). A person who has a blood pH above 7.45 is considered to be in alkalosis, and a pH above 7.8 is fatal. Some symptoms of alkalosis include cognitive impairment (which can progress to unconsciousness), tingling or numbness in the extremities, muscle twitching and spasm, and nausea and vomiting. Both acidosis and alkalosis can be caused by either metabolic or respiratory disorders. As discussed earlier in this chapter, the concentration of carbonic acid in the blood is dependent on the level of CO2 in the body and the amount of CO2 gas exhaled through the lungs. Thus, the respiratory contribution to acid-base balance is usually discussed in terms of CO2 (rather than of carbonic acid). Remember that a molecule of carbonic acid is lost for every molecule of CO2 exhaled, and a molecule of carbonic acid is formed for every molecule of CO2 retained. Figure 1. Symptoms of Acidosis and Alkalosis. Symptoms of acidosis affect several organ systems. Both acidosis and alkalosis can be diagnosed u Continue reading >>
Abg Analysis Article
the"6 Easy Steps to ABG Analysis" were developed to provide nurses with what? an accurate and systematic method of easily interpreting arterial blood gases 5. Does the CO2 or the HCO3 go the opposite direction of the ph? 6. Are the pO2 and the O2 saturation normal? Normal blood pH is 7.4, plus or minus 0.05, forming the range 7.35 to 7.45. If blood pH falls below 7.35 it is acidic. If blood pH rises above 7.45, it is alkalotic. If it falls in the normal range, label what side of 7.4 it falls on. Lower than 7.4 is normal/acidotic, and higher than 7.4 is normal/alkalotic. Label it. Normal pCO2 levels are 35-45 mmHg. Below 35 is alkalotic and above 45 is acidic. Label it. A Normal HCO3 level is 22-26 mEq/L. If below 22 then pt is acidic. If the HCO3is above 26, the patient is alkalotic. Label it. Step 4: Match the CO2 or the HCO3 with the pH Next match either the pCO2 or the HCO3 with the pH to determine the acid-base disorder. For example, if the pH is acidotic, the CO2 is acidotic, then the acid-base disturbance is being caused by the respiratory system = respiratory acidosis. If the pH is alkalotic and the HCO3 is alkalotic the acid-base disturbance is being caused by metabolic (renal) system = metabolic acidosis. Step 5: Does the CO2 or the HCO3 go the opposite direction of the pH? If so then there is compensation by that system. For example, if the pH is acidotic, the CO2 is acidotic, ash the HCO3 is alkalotic. The CO2 matches the pH making the primary acid-base disorder repiratory acidosis. The HCO3 is opposite of the pH and would be evidence of compensation of the metabolic system Step 6: Analyze the pO2 and the O2 saturation If they are below normal there is evidence of hypoxemia -The CO2 is the respiratory component of the ABG, and if it is low and the pH is high Continue reading >>
Respiratory And What Is The Opposite Of Acidosis
Respiratory and what is the opposite of acidosis? Alkalosis, and vice versa. 2. Example: if you have metabolic acidosis (decrease bicarb) what do we have to do with the pCO2? We have to get rid of it. If we decrease the nominator, we have to decrease the dominator in order for the equation to stay the same. Therefore, we have to blow off the CO2(hyperventilation). 3. Ventilation is a CO2term! Hyperventilation = Increase in respiratory rate allows for the blowing off of CO2, therefore results in respiratory alkalosis. For the treatment of respiratory alkalosis is to give the pt a paper bag and ask to breath in it, b/c then they are re-breathing their own CO2. Hypoventilation = Decrease in respiratory rate allows for the retention of CO2, therefore results in respiratory acidosis. Full compensation does not exist; you never bring back the pH to the normal range. There is one exception: chronic respiratory alkalosis in high altitude; ie mountain sickness (ie peru). C. Respiratory conditions: acidosis and alkalosis 1. Things that deal with CO2: a) Respiratory center is in medulla oblongata, which controls the breathing rate b) Upper airways if obstructed, there will be a problem getting rid of CO2. c) Chest bellows most imp muscle of respiration is diaphragm. On inspiration: the diaphragm goes down, the negative intrathroacic pressure increases, and air is sucked into the lungs and blood is sucked into the right side of the heart (this is why neck veins collapse on inspiration). Negative vacuum sucks blood and air into your chest. On expiration, there is a + intrathrocic pressure, pushing things out. It helps the left heart to push blood out and it also helps the lungs by pushing out air. 2. Examples: (a) Barbiturates or any drug that depresses the respiratory center will Continue reading >>

Definition Of Acidosis In Physiology.
Once oxygenation is restored, the acidosis clears quickly. When metabolic acidosis is severe and can no longer be compensated for adequately by the lungs, neutralizing the acidosis with infusions of bicarbonate may be required. One key to distinguish between respiratory and metabolic acidosis is that in respiratory acidosis, the CO2 is increased while the bicarbonate is either normal (uncompensated) or increased (compensated). Compensation occurs if respiratory acidosis is present, and a chronic phase is entered with partial buffering of the acidosis through renal bicarbonate retention. General symptoms of acidosis are described in relation to their location on the body. An excess of acid is called acidosis and an excess in bases is called alkalosis . The phrase "mixed acidosis," for example, refers to metabolic acidosis in conjunction with respiratory acidosis. Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. Differentiate among the acid-base disorders: metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis An excess of acid is called acidosis and an excess in bases is called alkalosis . The phrase "mixed acidosis," for example, refers to metabolic acidosis in conjunction with respiratory acidosis. Respiratory acidosis is a medical condition in which decreased ventilation (hypoventilation) causes increased blood carbon dioxide concentration and decreased pH (a condition generally called acidosis). Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. When the blood becomes acidic, respiratory acidosis occurs, which can cause tissue damage if too severe. Acidosis can be caused by hypoventilation (too little breathing), which reduces the removal rate of carbon dioxide, causing it Continue reading >>
acidosis [asā³Ä-doĀ“sis] 1. the accumulation of acid and hydrogen ions or depletion of the alkaline reserve (bicarbonate content) in the blood and body tissues, resulting in a decrease in pH. 2. a pathologic condition resulting from this process, characterized by increase in hydrogen ion concentration (decrease in pH). The optimal acid-base balance is maintained by chemical buffers, biologic activities of the cells, and effective functioning of the lungs and kidneys. The opposite of acidosis is alkalosis. adj., adj acidotĀ“ic. Acidosis usually occurs secondary to some underlying disease process; the two major types, distinguished according to cause, are metabolic acidosis and respiratory acidosis (see accompanying table). In mild cases the symptoms may be overlooked; in severe cases symptoms are more obvious and may include muscle twitching, involuntary movement, cardiac arrhythmias, disorientation, and coma. In general, treatment consists of intravenous or oral administration of sodium bicarbonate or sodium lactate solutions and correction of the underlying cause of the imbalance. Many cases of severe acidosis can be prevented by careful monitoring of patients whose primary illness predisposes them to respiratory problems or metabolic derangements that can cause increased levels of acidity or decreased bicarbonate levels. Such care includes effective teaching of self-care to the diabetic so that the disease remains under control. Patients receiving intravenous therapy, especially those having a fluid deficit, and those with biliary or intestinal intubation should be watched closely for early signs of acidosis. Others predisposed to acidosis are patients with shock, hyperthyroidism, advanced circulatory failure, renal failure, respiratory disorders, or liver disease. Continue reading >>
Acute Respiratory Alkalosis And Acidosis And Rabbit Intestinal Ion Transport In Vivo.
Acute respiratory alkalosis and acidosis and rabbit intestinal ion transport in vivo. The effects of acute respiratory alkalosis and acidosis on electrolyte transport in the rabbit ileum, colon, and gallbladder were studied. During in situ perfusion, anesthetized animals were ventilated with 0, 3, or 8% CO2 gas, creating states of alkalosis (pH 7.49 +/- 0.01, PCO2 = 27.0 +/- 0.9 mmHg, HCO3 = 21.7 mM), normocapnia (pH 7.38 +/- 0.02, PCO2 = 41.3 +/- 1.1 mmHg, HCO3 = 25.9 +/- 0.4 mM), and acidosis (pH 7.21 +/- 0.01, PCO2 = 66.3 +/- 1.3 mmHg, HCO3 = 28.1 +/- 0.8 mM). In the ileum alkalosis decreased the net absorption of water (-36%), sodium (-44%), and chloride (-27%), whereas acidosis had the opposite effect on water (+69%), sodium (+98%), and chloride (+32%) absorption and reduced bicarbonate secretion. Small changes in net potassium absorption occurred in the direction of water movement. There was no effect on the ileal transmural potential difference (PD). The colon and gallbladder did not respond to the acid-base disorders with changes in electrolyte transport or PD. These results suggest that systemic pH and/or PCO2 affect an electroneutral sodium chloride absorptive process in the rabbit ileum. The simple presence of this absorptive process in the gallbladder was not a sufficient basis for this organ to respond to alterations in systemic pH. Continue reading >>
How To Read Abgs Like A Boss: Master Acid-base Disorders!
How to Read ABGs Like a Boss: Master Acid-Base Disorders! Acid-base imbalances are an important concept of nursing practice, not to mention something youll need to learn in school. Teachers have different ways to teach students how to interpret ABGs, but heres my preferred method. ABG stands for Arterial Blood Gas. You will need to stick an artery to get ABG values. ABGs will include a few different lab values including pH, pCO2, and HCO3. Now that we have the normal values, we first will need to decide if the patient has some kind of acidosis versus alkalosis. Acidosis is defined as a pH lower than 7.35. The lower the pH, the more acidic the solution. Alkalosis is defined as a pH higher than 7.45. The higher the pH, the more alkalotic the solution. Question: Ms. Jones has a pH of 7.3. Does she have some sort of acidosis or alkalosis? Question: Ms. Jones has a pH of 7.5. Does she have some sort of acidosis or alkalosis? Ok great, you know how to tell if the patient is in acidosis or alkalosis, but now we need to know what has caused this change in pH. You have two causes: respiratory or metabolic. Respiratory concerns the fluctuation of the lab carbon dioxide (CO2). This should be easy to remember since we exhale carbon dioxide when we breathe out air. Metabolic concerns the fluctuations of the lab bicarbonate (HCO3). How will I know which is causing the problem? One of my favorite mnemonics is R.O.M.E. That stands for Respiratory Opposite, Metabolic Equal. How do I use this mnemonic? First, you need to determine the direction of your lab imbalances. Determine if pH is up or down from normal like we just learned. Draw an arrow pointing up or down near your pH value. Determine if the respiratory lab (CO2) is up or down from normal. Draw an arrow pointing up or down near Continue reading >>

Acidosis Has Opposite Effects On Neuronal Survival During Hypoxia And Reoxygenation
Acidosis has opposite effects on neuronal survival during hypoxia and reoxygenation Address correspondence and reprint requests to Runar Almaas, Department of Pediatric Research, Rikshospitalet, N0027 Oslo, Norway.

To study the effect of extracellular acidosis on apoptosis and necrosis during ischemia and reoxygenation, we exposed human postmitotic NT2N neurones to oxygen and glucose deprivation (OGD) followed by reoxygenation. In some experiments, pH of the cell medium was lowered to 5.9 during either OGD or reoxygenation or both. Staurosporine, used as a positive control for apoptosis, caused Poly(ADPribose)polymerase (PARP) cleavage and nuclear fragmentation, but no PARP cleavage and little fragmentation were seen after OGD. Low molecular weight DNA fragments were found after staurosporine treatment, but not after OGD. No protective effect of caspase inhibitors was seen after 3 h of OGD and 21 h of reoxygenation, but after 45 h of reoxygenation caspase inhibition induced a modest improvement in 3(4,5dimethylthiazol2yl)2,5diphenyltetrazolium bromide (MTT) cleavage. While acidosis during OGD accompanied by neutral medium during reoxygenation protected the neurones (MTT: 228 117% of neutral medium, p < 0.001), acidosis during reoxygenation only was detrimental (MTT: 38 25%, p < 0.01). We conclude that apoptotic mechanisms play a minor role after OGD in NT2N neurones. The effect of acidosis on neuronal survival depends on the timing of acidosis, as acidosis w Continue reading >>
