2nd line of defense, and it controls the amount of carbon dioxide in the arterial blood. In response to high CO2 levels are carbon dioxide in the blood the respiratory system will increased the depth and the rate of breathing.

Case history 3 Steve Burr, 38, has type 1 diabetes. He hasn't been feeling well for the last 3 days and hasn't eaten or injected his insulin. He's confused and lethargic. His respiratory rate is 32 breaths/minute, and his breath has a fruity odor. His serum glucose level is 620 mg/dL. While receiving 40% O2, his ABG values are: pH: 7.15 Paco2: 30 mm Hg PaO2Paco2: 130mm Hg HCO3-: 10 mm Hg SaO2: 94%.

Interpretation: These ABG values reveal metabolic acidosis with partial respiratory compensation. The patient's pH and HCO3- indicate acidosis. His Paco2 is lower than normal, reflecting the lungs' attempt to compensate. Because pH is abnormal, you know compensation isn't complete.

John Stewart, 22, is brought to the ED for an overdose of a tricyclic antidepressant. He's unconscious and has a respiratory rate of 5 to 8 breaths/minute. His ABG values are as follows: pH: 7.25 Paco2: 61 mm Hg PaO2Paco2: 76 mm Hg HCO3-: 26 mm Hg SaO2: 89%.

Interpretation: These ABG values reveal respiratory acidosis without compensation. The patient's pH and Paco2 are acidotic, and his HCO3- is normal, indicating no compensation. You would administer O2, as ordered. The patient may be intubated to protect his airway and placed on a mechanical ventilator. You would also treat the underlying cause by performing gastric lavage and administering activated charcoal. This patient's condition may progress to metabolic acidosis. If so, you would give sodium bicarbonate to reverse the acidosis.

Now, interpret these values: pH: 7.25 Paco2: 56 mm Hg PaO2 Paco2: 80 mm Hg HCO3-: 15 mm Hg SaO2 : 93%

Interpretation: These values reveal mixed acidosis. The pH, HCO3-, and Paco2 all indicate acidosis.

Try interpreting this set of ABG values without a clinical scenario: pH: 7.49 Paco2: 40 mm Hg PaO2 Paco2: 85 mm Hg HCO3-: 29 mm Hg SaO2: 90%

Interpretation: These values reveal uncompensated metabolic alkalosis. The pH and HCO3- indicate alkalosis. Paco2 is normal, indicating no compensation.

3rd line of defense, this system is slower to respond, but the response is more powerful and more long acting. If it sense the blood ph is too low meaning it is acidic then the kidneys will increase reabsorption of bicarbonate and will aslo excrete more hydrogen ions.
