212 Possible Causes for Bicarbonate Decreased, Hyperventilation

  • Acidosis

    Labs: General Arterial Blood Gas Arterial pH decreased Serum bicarbonate decreased PaCO2 decreased PaCO2 drops 1.2 mmHg per 1 meq/L bicarbonate fall Calculated PaCO2 1.5 x[] Previous Index Next 5.5.1 Hyperventilation Compensation for a metabolic acidosis is hyperventilation to decrease the arterial pCO 2.[] A persistent decrease in the rate of renal bicarbonate reabsorption that maintains the decreased plasma bicarbonate level. c.[]

  • Respiratory Alkalosis

    Measurement of the serum bicarbonate permits definitive diagnosis: acute respiratory alkalosis: serum bicarbonate decreases by 2 mM for every 10 mmHg (or 1.33kPa) decrease[] Abstract Hyperventilation in pregnancy is a cause of chronic respiratory alkalosis.[] RESULTS: For each decrease of 1 mm Hg (0.13 kPa) in the PaCO2, the plasma bicarbonate concentration decreased by 0.41 mmol per liter in the subjects who started with a normal[]

  • Metabolic Acidosis

    Thus, correcting acidosis in CKD with bicarbonate decreases IL-10 secretion. Its significance needs to be further investigated. Copyright 2015 Elsevier Masson SAS.[] In patients 1 and 2, hyperventilation delayed weaning mechanical ventilation.[] Labs: General Arterial Blood Gas Arterial pH decreased Serum bicarbonate decreased PaCO2 decreased PaCO2 drops 1.2 mmHg per 1 meq/L bicarbonate fall Calculated PaCO2 1.5 x[]

  • Hyperventilation

    […] via a decrease in bicarbonate reabsorption.[] […] alkalosis Shallow water blackout, the role of hyperventilation in some drowning incidents[] There is approximately a 2% decrease in CBF for every 1 mmHg decrease in PaCO2 levels.[]

  • Acute Alcohol Intoxication

    […] in serum bicarbonate concentration.[] Accumulation of the alcohols in the blood can cause an increment in the osmolality, and accumulation of their metabolites can cause an increase in the anion gap and a decrease[]

  • Psychogenic Hyperventilation

    Compensation: Metabolic side compensates for respiratory acidosis by decreasing renal chloride excretion, leading to decreased strong-ion difference and decreased bicarbonate[] […] the hyperventilation were absent.[] […] buffer system occur due to the lowered pCO2 and this results in a slight decrease in HCO3-. magnitude: drop in HCO3- by 2 mmol/l for every 10mmHg decrease in pCO2 from the[]

  • Respiratory Acidosis

    HCl was infused at a constant rate of 25 mmol/h until the bicarbonate concentration decreased less than 26 mmol/L, or until the pH decreased less than 7.35 (initial pH greater[] INTERVENTIONS: Patients were randomly allocated to one of three groups by arterial carbon dioxide tension level (PaCO2; mmHg) after induction: hyperventilation group (PaCO2[] "Respiratory alkalosis" caused by decreased carbonic acid. 3. "Metabolic acidosis" caused by decreased bicarbonate, and/or buildup of acids from metabolic processes. 4.[]

  • Acute Hyperventilation

    This decline in U-B PCO2 with acute hyperventilation could not be attributed to changes in urine flow, phosphate, or bicarbonate excretion, suggesting, therefore, a decrease[] Symptoms of hyperventilation are likewise independent of the inspired oxygen concentration for the range studied.[] […] res'pir-ă-tōr-ē al'kă-lō'sis ) Alkalosis resulting from an abnormal loss of CO 2 produced by hyperventilation, either active or passive, with concomitant reduction in arterial bicarbonate[]

  • Chronic Obstructive Pulmonary Disease

    This may result from decreased oxygen delivery such as occurs in hypoxaemia, or low cardiac output states or conditions such as sepsis where oxygen consumption is impaired[] ABGs Usually near normal due to compensatory hyperventilation; arterial pO 2 is in the mid-70s, pCO 2 is low to normal; PPs have tidal volume and retraction of accessory[] The body compensates with lowered cardiac output and hyperventilation.[]

  • Acid Base Disorder

    In metabolic acidosis (decrease bicarbonate), the PCO2 must decrease to maintain the ratio of bicarbonate to PCO2.[] PaCO2 (4.7 kPa): Primary respiratory alkalosis (hyperventilation) if pH 7.45 and HCO3– normal.[] Metabolic acidosis general Metabolic acidosis • if calculated AG 12 or if Excess gap HCO3 is greater than 26 non anion gap metabolic acidosis • Compensation: respiratory hyperventilation[]
