18 Possible Causes for Bicarbonate Decreased, Cognitive Defect, Hypocapnia

  • 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[fpnotebook.com] […] during sustained hypocapnia. 27. 2.[slideshare.net] Often these diseases stimulate ventilation and hypocapnia due to reflex receptors and hypoxia.[emedicine.com]

  • Acute Alcohol Intoxication

    […] in serum bicarbonate concentration.[cjasn.asnjournals.org] 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[cjasn.asnjournals.org]

  • Chronic Kidney Insufficiency

    Neutralization of dietary acid with sodium bicarbonate decreases kidney injury and slows kidney function decline, but sodium bicarbonate (baking soda) has sodium; so, doctors[nutritionfacts.org] Moderate metabolic acidosis (plasma bicarbonate content 15 to 20 mmol/L) is characteristic.[merckmanuals.com] Potassium may be high and bicarbonate levels may be low if you have CKD. There may also be an increase of acid in the blood.[healthline.com]

  • Diabetic Ketotic Coma

    Indeed this is much higher then expected given the relatively modest decrease in bicarbonate.[anaesthesiamcq.com] […] play a part in the development of cerebral edema, recent data suggest that cerebral edema in children with DKA is related to brain ischemia. 42 In children with DKA, both hypocapnia[spectrum.diabetesjournals.org] Many clinicians have observed worsening of acidemia, as evidenced by decreased serum bicarbonate concentration, after aggressive resuscitation with normal saline.[ahcmedia.com]

  • Hypercapnia

    The increase in PaCO 2 , in turn, decreases the bicarbonate (HCO 3 – )/PaCO 2 ratio, thereby decreasing the pH.[emedicine.medscape.com] Conclusions Severe hypercapnia and hypocapnia can cause neonatal brain injury and lung injury.[link.springer.com] The renal system participates in acid-base regulation by increasing or decreasing levels of bicarbonate (HCO3-).[rtmagazine.com]

  • High Altitude Cerebral Edema

    It is a carbonic anhydrase inhibitor that causes a bicarbonate diuresis and metabolic acidosis.[lifeinthefastlane.com] Prolonged exertion in low oxygen also causes serious hypocapnia, lower carbon dioxide in the bloodstream, which may play a role in HACE.[en.wikipedia.org] […] regions of South America and the Himalayas •Extreme altitude, 5490 m ( 18,000 ft) complete acclimatization generally is not possible accompanied by severe hypoxemia and hypocapnia[slideshare.net]

  • Acute Renal Failure

    […] buildup of potassium Sodium bicarbonate is used to decrease acid buildup Acute Kidney Failure Follow-up The doctor will arrange follow-up visits as needed for the underlying[emedicinehealth.com] The individual's ability to live with multisystem diseases, cope with ensuing problems, and care for himself are markedly diminished. failure of artificial pacemaker A defect[medical-dictionary.thefreedictionary.com] Sodium bicarbonate hydration improves urinary alkalinization, as opposed to normal saline hydration, which presumably works by decreasing the concentration of contrast media[circ.ahajournals.org]

  • Cerebral Edema

    In addition, bicarbonate therapy causes central nervous system hypoxia in laboratory animals with diabetic ketoacidosis. 33 Hyperglycemia superimposed on an ischemic insult[nejm.org] Theories include osmotic disequilibrium between brain and plasma as glucose is rapidly lowered, decreased plasma oncotic pressure due to infusion of large amounts of saline[ncbi.nlm.nih.gov] Prolonged exertion in low oxygen also causes serious hypocapnia, lower carbon dioxide in the bloodstream, which may play a role in HACE.[en.wikipedia.org]

  • Renal Tubular Acidosis

    […] resorption Decrease in aldosterone secretion or activity Plasma bicarbonate (mEq/L or mmol/L) Frequently 15, occasionally 10 Usually 12–20 Usually 17 Plasma potassium Usually[msdmanuals.com] When the hypocapnia is repaired, the return of the PaCO 2 to normal unveils a transient metabolic acidosis, which will self-correct shortly.[emedicine.com] Other features include developmental delay, short stature, cognitive defects, and a history of multiple fractures by adolescence.[doi.org]

  • Diabetes Mellitus

    Bicarbonate therapy The use of bicarbonate in DKA is controversial ( 62 ) because most experts believe that during the treatment, as ketone bodies decrease there will be adequate[web.archive.org] To induce hypocapnia, subjects hyperventilated to reduce CO 2 to 25 mmHg.[ncbi.nlm.nih.gov] 'cognition', 'mixed depression and dementia', 'presenile dementia', 'frontotemporal dementia', 'dementia' or 'multiinfarct dementia', 'senile dementia', 'cognitive defect'[doi.org]
