HCO3- ; The HCO3- ion indicates whether a metabolic problem is present (such as ketoacidosis). A low HCO3- indicates metabolic acidosis, a high HCO3- indicates metabolic alkalosis. HCO3- levels can also become abnormal when the kidneys are working to compensate …

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 …

• The low PO2 in the blood stimulates the peripheral chemoreceptors to send nerve impulses to the respiratory centers which stimulate the respiratory muscles, increasing ventilation. More oxygen is inhaled, and the arterial PO2 returns to normal levels.

For example, bicarbonate (HCO3- , the way CO2 travels in the blood) is a weak base that is in constant equilibrium with carbonic acid (H2CO3): HCO3- + H+ ( H2CO3. If the blood becomes too acidic, bicarbonate removes H+ by becoming carbonic acid and vice versa. Depending on the pH of the blood, kidneys will remove H+ or bicarbonate as needed.

HCO3- level in blood is normally between 22 and 27 If the body becomes more acid, HCO3- levels fall as HCO3- ions bind to hydrogen, and breathing increases, to reduce levels of CO2. Conversely, as the pH rises, HCO3- levels rise.

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 - …

His arterial blood gases were all out of normal range. His pH and pO2 was very low, his pCO2 and HCO3- levels were high. This means his body is in partially compensated respiratory acidosis because his CO2 levels are very high, causing his pH to go down, and since his HCO3- levels are high as well, this means his kidneys are trying to return ...
