ABG Interpretation By Rnpedia

The given values of pH, CO2, and HCO3 fall within the normal range for blood pH and bicarbonate levels. A pH of 7.35 is within the normal range of 7.35-7.45, indicating a balanced acidity level. The CO2 level of 42 is also within the normal range of 35-45 mmHg, indicating a normal level of carbon dioxide in the blood. The HCO3 level of 23 is within the normal range of 22-28 mEq/L, indicating a normal bicarbonate level. Therefore, based on these values, the overall blood pH and bicarbonate levels are considered normal.

Based on the given values of pH, CO2, and HCO3, the pH is higher than the normal range of 7.35-7.45, indicating alkalosis. The CO2 level is lower than the normal range of 35-45 mmHg, suggesting respiratory alkalosis. The HCO3 level is within the normal range of 22-26 mEq/L, indicating compensation for the alkalosis. Therefore, the correct answer is respiratory alkalosis.

The given values of pH, CO2, and HCO3 indicate that the pH is slightly elevated (alkalosis) at 7.48. The CO2 level is within the normal range at 19, suggesting that there is no respiratory acidosis. However, the HCO3 level is also within the normal range at 14, indicating that there is no metabolic acidosis. Therefore, the condition can be classified as partly compensated respiratory alkalosis, where the body is attempting to compensate for the alkalosis but has not fully restored the acid-base balance.

The given values of pH, CO2, and HCO3 indicate that the patient has a pH below the normal range (7.35-7.45), indicating acidosis. The CO2 value is elevated (normal range 35-45 mmHg), suggesting respiratory acidosis. The HCO3 value is also elevated (normal range 22-28 mEq/L), indicating metabolic compensation. However, the compensation is not fully effective as the pH is still below normal. Therefore, the correct answer is partly compensated respiratory acidosis.

Compensated metabolic acidosis is characterized by a low pH (acidemia) primarily due to a decrease in bicarbonate (HCO3-), which is the body's primary buffer system. To compensate, the respiratory system increases ventilation to blow off CO2, lowering PaCO2. Option c) demonstrates this pattern: low pH, low HCO3-, and a low PaCO2 indicating respiratory compensation.

Based on the given values of pH, CO2, and HCO3, the pH is below the normal range (7.35-7.45), indicating acidosis. Additionally, the CO2 level is above the normal range (35-45 mmHg), indicating respiratory acidosis. However, the HCO3 level is below the normal range (22-28 mEq/L), indicating metabolic acidosis. Therefore, the combination of respiratory acidosis and metabolic acidosis suggests a combined acidosis.

The given values of pH, CO2, and HCO3 indicate a combined alkalosis. A pH of 7.75 is higher than the normal range of 7.35-7.45, indicating alkalosis. Additionally, the CO2 level of 29 is lower than the normal range of 35-45 mmHg, also indicating alkalosis. The HCO3 level of 40 is within the normal range of 22-28 mEq/L, but it is on the higher side, further supporting the presence of alkalosis. Therefore, the combination of these values suggests a combined alkalosis.

The given values of pH, CO2, and HCO3 indicate a disturbance in both respiratory and metabolic components of acid-base balance. The pH value of 7.33 indicates acidemia, which is lower than the normal range of 7.35-7.45. The elevated CO2 level of 66 suggests respiratory acidosis, as it is higher than the normal range of 35-45 mmHg. The HCO3 level of 35 falls within the normal range of 22-28 mEq/L, indicating metabolic compensation. Therefore, the correct answer is partly compensated respiratory acidosis, as there is evidence of both respiratory and metabolic disturbances.

The pH of 6.68 indicates severe acidosis. Both the elevated PaCO₂ (respiratory cause) and decreased HCO₃⁻ (metabolic cause) show that the patient is experiencing combined metabolic and respiratory acidosis. This condition is life-threatening and requires immediate medical attention.

The given values of pH, CO2, and HCO3 indicate a respiratory alkalosis. The pH value of 7.50 is higher than the normal range, indicating alkalosis. The CO2 value of 9 is lower than the normal range, indicating a decrease in carbon dioxide levels. The HCO3 value of 7 is within the normal range, suggesting that the kidneys have not fully compensated for the respiratory alkalosis. Therefore, the correct answer is "PARTLY COMPENSATED RESPIRATORY ALKALOSIS."
