Bicarbonate levels in blood
CO2 blood test: MedlinePlus Medical Encyclopedia
When the PaO2 falls below 50 mmHg, you need to act promptly to restore it to normal levels HCO3- is the actual bicarbonate level in the blood. It only reflects changes in the bicarbonate buffer system, the most important of the blood buffers. In Calgary the normal range is 20 - 24

The blood HCO3 concentration needed to achieve this pH rarely exceeds 15 mEq/L if patient is capable of maintaining pCO2 < 35 mmHg. (See acid-base nomogram). Bicarbonate deficit = (15 – plasma [HCO3]) x Wt (kg) x 0.3. Note that bicarbonate given IV distributes acutely in only about ½ the total body water (TBW = Wt (kg) x 0.6).

Alkalosis - blood pH above 7.45. Alkalosis causes excitability of nervous tissue - spasms, convulsions & death. Respiratory acidosis and respiratory alkalosis are primary disorders of blood PCO2 (Table 27.4) Metabolic acidosis and metabolic alkalosis are primary disorders of bicarbonate concentration

Excess H+ ions in the blood will trigger increased respiration to reduce the acidity and increase the pH of the blood. If CO2 levels are too low, as in hyperventilation, then bicarbonate ions (HCO3-) don’t have many H+ ions to bind. The kidneys will eliminate excess HCO3- in the urine.

Increased levels of CO2 in the blood (surprisingly, O2 not directly involved) raise H+ concentrations (because of increased levels of bicarbonate) that are detected by the brain; result is deeper and faster breathing (hyperventilation). Low CO2 levels result in slowed breathing (hypoventilation) to bring CO2 levels …

Bicarbonate 16 mEq/L 21-32 According to KDOQI guidelines, serum bicarbonate levels are reduced in patients with a GFR less than 60 mL/min/1.73 m2. The low levels may indicate acidemia and overall protein catabolic state. Low serum bicarbonate is often correlated with …

By monitoring your patient’s carbon dioxide, bicarbonate, and pH levels you can successfully prevent and treat any acid–base imbalances. Respiratory acidosis is an acid–base imbalance that occurs when the pH is decreased below 7.35, and the partial pressure of carbon dioxide (PCO2) is …
