(Usually in clinical practice, H+ concentration is expressed as pH.) PaCO2 (Arterial CO2 concentration normal = 3545 mm Hg). HCO3 (Serum electrolytes normal = 2231 mmol/liter). Acidosis is a process that causes the accumulation of acid. Alkalosis is a process that causes the accumulation of alkali. The most common causes in the surgical practice include: Diuretic therapy (e.g., contraction alkalosis). Acid loss through GI secretions (e.g., nasogastric suctioning, vomiting). Exogenous administration of HCO3 or HCO3 precursors (e.g., citrate in blood). Chloride-unresponsive metabolic alkalosis is comparatively less common and includes: Renal tubular Cl wasting (Bartters syndrome) Measurement of urinary chloride concentration. Suggestive causes of the metabolic alkalosis if Urine Cl concentration is <15 mmol/liter: Sughgestive causes of the metabolic alkalosis if Urine Cl concentration is > 20 mmol/liter: Treatment principles in metabolic alkalosis:[ edit ] Removing and identifying underlying causes, Discontinuing exogenous alkali, repairing Cl, K+, and volume deficits. Correction of volume deficits (can be used 0.9% NaCl) and hypokalemia. H2-receptor antagonists or other acid-suppressing medications can be used after vomiting or nasogastric suctioning. Acetazolamide (5 mg/kg/day IV or PO) can be used. Eases fluid mobilization while decreasing renal HCO3 reabsorption. Tolerance to this diuretic may develop after 23 days. Ammonium chloride (NH4Cl) can be used in severe alkalemia (HCO3 >40 mmol/liter; rate not exceeding 5 ml/minute). Approximately one-half of the calculated volume of NH4Cl is usually administered and the acid-base status and Cl concentration is usually rechecked to determine the need of further treatment. Hepatic failure is contraindication for NH4Cl. HCl m Continue reading >>

This condition is brought about by a problem either involving the lungs and respiratory system or signals from the brain that control breathing. There is primary increase in Pco2 with compensatory increase in HCO3 ; pH usually low but may be near normal. (Ventilatory failure; Respiratory failure; Acidosis respiratory) Carbon dioxide is produced constantly as the body burns energy, and this CO2 will accumulate rapidly if the lungs do not adequately dispel it through alveolar ventilation. Alveolar hypoventilation thus leads to an increased PaCO2 (called hypercapnia). The increase in PaCO2 in turn decreases the HCO3/PaCO2 ratio and decreases pH resulting respiratory acidosis. Etiology: HypoventilationDiseases of the airways (such as asthma and chronic obstructive lung disease), which send air into and out of the lungsDiseases of the chest (such as scoliosis), which make the lungs less efficient at filling and emptyingDiseases affecting the nerves and muscles that "signal" the lungs to inflate or deflateDrugs that suppress breathing (including powerful pain medicines, such as narcotics, and "downers," such as benzodiazepines), especially when combined with alcoholSevere obesity, which restricts how much the lungs can expand Signs and symptoms: Symptoms an Continue reading >>

Metabolic Acidosis: Causes, Symptoms, And Treatment

Metabolic Acidosis: Causes, Symptoms, And Treatment

The Terrible Effects of Acid Acid corrosion is a well-known fact. Acid rain can peel the paint off of a car. Acidifying ocean water bleaches and destroys coral reefs. Acid can burn a giant hole through metal. It can also burn holes, called cavities, into your teeth. I think I've made my point. Acid, regardless of where it's at, is going to hurt. And when your body is full of acid, then it's going to destroy your fragile, soft, internal organs even more quickly than it can destroy your bony teeth and chunks of thick metal. What Is Metabolic Acidosis? The condition that fills your body with proportionately too much acid is known as metabolic acidosis. Metabolic acidosis refers to a physiological state characterized by an increase in the amount of acid produced or ingested by the body, the decreased renal excretion of acid, or bicarbonate loss from the body. Metabolism is a word that refers to a set of biochemical processes within your body that produce energy and sustain life. If these processes go haywire, due to disease, then they can cause an excess production of hydrogen (H+) ions. These ions are acidic, and therefore the level of acidity in your body increases, leading to acidemia, an abnormally low pH of the blood, <7.35. The pH of the blood mimics the overall physiological state in the body. In short, a metabolic process is like a power plant producing energy. If a nuclear power plant goes haywire for any reason, then we know what the consequences will be: uncontrolled and excessive nuclear energetic reactions leading to the leakage of large amounts of radioactive material out into the environment. In our body, this radioactive material is acid (or hydrogen ions). Acidemia can also occur if the kidneys are sick and they do not excrete enough hydrogen ions out of th Continue reading >>

American Thoracic Society - Interpretation Of Arterial Blood Gases (abgs)

Interpretation of Arterial Blood Gases (ABGs) Chief, Section of Pulmonary, Critical Care & Sleep Medicine Bridgeport Hospital-Yale New Haven Health Assistant Clinical Professor, Yale University School of Medicine (Section of Pulmonary & Critical Care Medicine) Interpreting an arterial blood gas (ABG) is a crucial skill for physicians, nurses, respiratory therapists, and other health care personnel. ABG interpretation is especially important in critically ill patients. The following six-step process helps ensure a complete interpretation of every ABG. In addition, you will find tables that list commonly encountered acid-base disorders. Many methods exist to guide the interpretation of the ABG. This discussion does not include some methods, such as analysis of base excess or Stewarts strong ion difference. A summary of these techniques can be found in some of the suggested articles. It is unclear whether these alternate methods offer clinically important advantages over the presented approach, which is based on the anion gap. Step 1: Assess the internal consistency of the values using the Henderseon-Hasselbach equation: If the pH and the [H+] are inconsistent, the ABG is probably not valid. Step 2: Is there alkalemia or acidemia present? Remember: an acidosis or alkalosis may be present even if the pH is in the normal range (7.35 7.45) You will need to check the PaCO2, HCO3- and anion gap Step 3: Is the disturbance respiratory or metabolic? What is the relationship between the direction of change in the pH and the direction of change in the PaCO2? In primary respiratory disorders, the pH and PaCO2 change in opposite directions; in metabolic disorders the pH and PaCO2 change in the same direction. Decrease in [HCO3-] = 5( PaCO2/10) to 7( PaCO2/10) If the observed compensa Continue reading >>

Blood Gas Analysis--insight Into The Acid-base Status Of The Patient

Acid-Base Physiology Buffers H+ A- HCO3- CO2 Buffers H+ A- CO2 Cells Blood Kidney Lungs Fluids, Electrolytes, and Acid-Base Status in Critical Illness Blood Gas Analysis--Insight into the Acid-Base status of the Patient The blood gas consists of pH-negative log of the Hydrogen ion concentration: -log[H+]. (also, pH=pK+log [HCO3]/ 0.03 x pCO2). The pH is always a product of two components, respiratory and metabolic, and the metabolic component is judged, calculated, or computed by allowing for the effect of the pCO2, ie, any change in the pH unexplained by the pCO2 indicates a metabolic abnormality. CO +H 0ºº H CO ººHCO + H2 2 2 3 3 - + CO2 and water form carbonic acid or H2CO3, which is in equilibrium with bicarbonate (HCO3-)and hydrogen ions (H+). A change in the concentration of the reactants on either side of the equation affects the subsequent direction of the reaction. For example, an increase in CO2 will result in increased carbonic acid formation (H2CO3) which leads to an increase in both HCO3- and H+ (\pH). Normally, at pH 7.4, a ratio of one part carbonic acid to twenty parts bicarbonate is present in the extracellular fluid [HCO3-/H2CO3]=20. A change in the ratio will affect the pH of the fluid. If both components change (ie, with chronic compensation), the pH may be normal, but the other components will not. pCO -partial pressure of carbon dioxide. Hypoventilation or hyperventilation (ie, minute2 ventilation--tidal volume x respitatory rate--imperfectly matched to physiologic demands) will lead to elevation or depression, respectively, in the pCO2. V/Q (ventilation/perfusion) mismatch does not usually lead to abnormalities in PCO2 because of the linear nature of the CO2 elimination curve (ie, good lung units can make up for bad lung units).

Difference Between Acidosis And Alkalosis | Acidosis Vs Alkalosis

Difference Between Acidosis And Alkalosis | Acidosis Vs Alkalosis

Difference Between Acidosis and Alkalosis | Acidosis vs Alkalosis Summary:Difference Between Acidosis and Alkalosis is thatAcidosis is the reduction in pH (increase in H+ concentration) below normal range. WhileAlkalosis is the increase in pH (decrease in H+ concentration) above the normal range. Acidosis is the reduction in pH (increase in H+ concentration) below normal range.Acidosis is produced by: Increase in partial pressure of CO2 in the body fluids particularly in arterial blood Alkalosis is the increase in pH (decrease in H+ concentration) above the normal range.Alkalosis is produced by: Decrease in partial pressure of CO2 in the arterial blood Since the partial pressure of CO2 (pCO2 ) in arterial blood is controlled by lungs, the acid-base disturbances produced by the change in arterial pCO2 are called the respiratory disturbances. On the other hand, the disturbances in acid-base status produced by the change in HCO3 concentration are generally called the metabolic disturbances.Thus the acid-base disturbances are: Respiratory acidosis is the acidosis that is caused by alveolar hypoventilation. During hypoventilation the lungs fail to expel CO2 , which is produced in the tissues. CO2 is the major end product of oxidation of carbohydrates, proteins and fats. CO2 accumulates in blood where it reacts with water to form carbonic acid, which is called respiratory acid. Carbonic acid dissociates into H+ and HCO3 . The increased H+ concentration in blood leads to decrease in pH and acidosis. Normal partial pressure of CO2 in arterial blood is about 40 mm Hg. When it increases above 60 mm Hg acidosis occurs. Respiratory alkalosis is the alkalosis that is caused by alveolar hyperventilation. Hyperventilation causes excess loss of CO2 from the body. Loss of CO2 leads to Continue reading >>

Build up of CO2 in the blood and causes blood to become more acidic, brought on by breathing difficulty What are the main causes of respiratory acidosis? Disease that affect lungs to inflate or deflate (eg of nerves and muscles) If someone is in respiratory acidosis, they will have a high CO2 (>40) and a slightly raised HCO3-. What happens to the ratio and pH? Ratio of HCO3-/PaCO2 decreases and therefore pH also decreases. Look at graph in powerpoint to understand why does the pH of CSF change more rapidly than that of the blood CO2 can diffuse across BBB whereas HCO3- can't (ion). CSF has little protein in it to act as a buffer how does low blood pH affect brain blood flow? increases overall brain blood flow (might mask a decrease to some brain areas) What are the signs and symptoms of Respiratory Acidosis? Conditions for acute respiratory acidosis and how is it caused? PaCO2 above 47mmHg (6.3kPa)with ACIDAEMIA. depression of central respiratory center by cerebral disease inability to ventilate because of neuromuscular disease (eg myasthenia gravis) or airway obstruction due to asthma or COPD Conditions for chronic respiratory acidosis and how is it caused PaCO2>47mmHg, BUT blood pH is normal/near normal This is because renal compensation occurs, producing HCO3- COPD - decreased response to hypoxia and hypercapnia, decreased diaphragm function neuromuscular disorders eg amyotrophic lateral sclerosis explain metabolic compensation for respiratory acidosis high [H+] stimulates kidney to generate and retain bicarb What is the max level of plasma HCO3 that can be reached in compensating metabolic alkalosis?

Acidosis And Alkalosis | Harrison's Principles Of Internal Medicine, 19e | Accessmedicine | Mcgraw-hill Medical

Systemic arterial pH is maintained between 7.35 and 7.45 by extracellular and intracellular chemical buffering together with respiratory and renal regulatory mechanisms. The control of arterial CO2 tension (Paco2) by the central nervous system (CNS) and respiratory system and the control of plasma bicarbonate by the kidneys stabilize the arterial pH by excretion or retention of acid or alkali. The metabolic and respiratory components that regulate systemic pH are described by the Henderson-Hasselbalch equation: Under most circumstances, CO2 production and excretion are matched, and the usual steady-state Paco2 is maintained at 40 mmHg. Underexcretion of CO2 produces hypercapnia, and overexcretion causes hypocapnia. Nevertheless, production and excretion are again matched at a new steady-state Paco2. Therefore, the Paco2 is regulated primarily by neural respiratory factors and is not subject to regulation by the rate of CO2 production. Hypercapnia is usually the result of hypoventilation rather than of increased CO2 production. Increases or decreases in Paco2 represent derangements of neural respiratory control or are due to compensatory changes in response to a primary alteration in the plasma [HCO3]. DIAGNOSIS OF GENERAL TYPES OF DISTURBANCES The most common clinical disturbances are simple acid-base disorders; i.e., metabolic acidosis or alkalosis or respiratory acidosis or alkalosis. Primary respiratory disturbances (primary changes in Paco2) invoke compensatory metabolic responses (secondary changes in [HCO3]), and primary metabolic disturbances elicit predictable compensatory respiratory responses (secondary changes in Paco2). Physiologic compensation can be predicted from the relationships displayed in Table 66-1 . In general, with one exception, compensatory res Continue reading >>

You can manage this and all other alerts in My Account ALTHOUGH unintended or deliberate variation of the arterial carbon dioxide partial pressure (PaCO2) is common in anesthetic practice, little is known about the myocardial consequences of respiratory alkalosis and acidosis in humans. Previous experimental studies have shown inconsistent results with respect to the effects of PaCO2on myocardial blood flow (MBF), myocardial metabolism, and global hemodynamics. This may have been caused in part by differences in the experimental design of the investigations. [1-6] Although most studies have shown that hypercapnia augments MBF above metabolic demands, [3,7-9] the results with respect to the effects of hypocapnia vary. [3,4] Furthermore, it seems questionable to transfer conclusions from experiment Continue reading >>

Respiratory Acidosis

Respiratory Acidosis

What is respiratory acidosis? Respiratory acidosis is a condition that occurs when the lungs can’t remove enough of the carbon dioxide (CO2) produced by the body. Excess CO2 causes the pH of blood and other bodily fluids to decrease, making them too acidic. Normally, the body is able to balance the ions that control acidity. This balance is measured on a pH scale from 0 to 14. Acidosis occurs when the pH of the blood falls below 7.35 (normal blood pH is between 7.35 and 7.45). Respiratory acidosis is typically caused by an underlying disease or condition. This is also called respiratory failure or ventilatory failure. Normally, the lungs take in oxygen and exhale CO2. Oxygen passes from the lungs into the blood. CO2 passes from the blood into the lungs. However, sometimes the lungs can’t remove enough CO2. This may be due to a decrease in respiratory rate or decrease in air movement due to an underlying condition such as: There are two forms of respiratory acidosis: acute and chronic. Acute respiratory acidosis occurs quickly. It’s a medical emergency. Left untreated, symptoms will get progressively worse. It can become life-threatening. Chronic respiratory acidosis develops over time. It doesn’t cause symptoms. Instead, the body adapts to the increased acidity. For example, the kidneys produce more bicarbonate to help maintain balance. Chronic respiratory acidosis may not cause symptoms. Developing another illness may cause chronic respiratory acidosis to worsen and become acute respiratory acidosis. Initial signs of acute respiratory acidosis include: headache anxiety blurred vision restlessness confusion Without treatment, other symptoms may occur. These include: sleepiness or fatigue lethargy delirium or confusion shortness of breath coma The chronic form of Continue reading >>

Respiratory Alkalosistreatment & Management

Respiratory Alkalosistreatment & Management

Respiratory AlkalosisTreatment & Management Author: Ryland P Byrd, Jr, MD; Chief Editor: Zab Mosenifar, MD, FACP, FCCP more... The treatment of respiratory alkalosis is primarily directed at correcting the underlying disorder. Respiratory alkalosis itself is rarely life threatening. Therefore, emergent treatment is usually not indicated unless the pH level is greater than 7.5. Because respiratory alkalosis usually occurs in response to some stimulus, treatment is usually unsuccessful unless the stimulus is controlled. If the PaCO2 is corrected rapidly in patients with chronic respiratory alkalosis, metabolic acidosis may develop due to the renal compensatory drop in serum bicarbonate. In mechanically ventilated patients who have respiratory alkalosis, the tidal volume and/or respiratory rate may need to be decreased. Inadequate sedation and pain control may contribute to respiratory alkalosis in patients breathing over the set ventilator rate. In hyperventilation syndrome, patients benefit from reassurance, rebreathing into a paper bag during acute episodes, and treatment for underlying psychological stress. Sedatives and/or antidepressants should be reserved for patients who have not responded to conservative treatment. Beta-adrenergic blockers may help control the manifestations of the hyperadrenergic state that can lead to hyperventilation syndrome in some patients. [ 2 ] In patients presenting with hyperventilation, a systematic approach should be used to rule out potentially life-threatening, organic causes first before considering less serious disorders. Based on the findings from the history, physical examination, laboratory studies, and imaging modalities, the necessity for assistance from consultants such as pulmonologists, neurologists, or nephrologists can b Continue reading >>

Respiratory Acidosis

Respiratory Acidosis

Respiratory Acidosisis an acid-base imbalance characterized by increased partial pressure of arterial carbon dioxide and decreased blood pH. The prognosis depends on the severity of the underlying disturbance as well as the patients general clinical condition. Compensatory mechanisms include (1) an increased respiratory rate; (2) hemoglobin (Hb) buffering, forming bicarbonate ions and deoxygenated Hb; and (3) increased renal ammonia acid excretions with reabsorption of bicarbonate. Acute respiratory acidosis:Associated with acute pulmonary edema, aspiration of foreign body, overdose of sedatives/barbiturate poisoning, smoke inhalation, acute laryngospasm, hemothorax / pneumothorax , atelectasis, adult respiratory distress syndrome (ARDS), anesthesia/ surgery , mechanical ventilators, excessive CO2intake (e.g., use of rebreathing mask, cerebral vascular accident [CVA] therapy), Pickwickian syndrome. Chronic respiratory acidosis:Associated with emphysema , asthma , bronchiectasis; neuromuscular disorders (such as Guillain-Barr syndrome and myasthenia gravis); botulism; spinal cord injuries. Condition, prognosis, and treatment needs understood. Plan in place to meet needs after discharge. This condition does not occur in isolation, but rather is a complication of a broader health problem/disease or condition for which the severely compromised patient requires admission to a medical-surgical or subacute unit. Main Article: Respiratory Acidosis Nursing Care Plan Remain alert for critical changes in patients respiratory, CNS and cardiovascular functions. Report such changes as well as any variations in ABG values or electrolyte status immediately. Maintain patent airway and provide humidification if acidosis requires mechanical ventilation .
