This calculator only differentiates between acute (pH abnormal) and compensated (pH normal). Compensation can be seen when both the PCO 2 and HCO 3 rise or fall together to maintain a normal pH.

Are the pCO2 or HCO3 abnormal? Which one appears to influence the pH? If both the pCO2 and HCO3 are abnormal, the one which deviates most from the norm is most likely causing an abnormal pH.

Mar 2, 2025 · PaCO2: Higher than 50 mmHg suggests hypercapnia and may indicate respiratory failure, especially if accompanied by a low or declining pH. pH: Values below 7.30 indicate severe acidosis and suggest that the respiratory system is failing to maintain acid-base balance.

Feb 18, 2022 · Partial pressure of carbon dioxide (PaCO2): This measures the amount of carbon dioxide in your blood and how well carbon dioxide can move out of your body. pH: This measures the balance of acids and bases in your blood, known as your blood pH level. The pH of blood is usually between 7.35 and 7.45.

pH < 7.35 acidemia pH > 7.45 alkalemia. This is usually the primary disorder; Remember: an acidosis or alkalosis may be present even if the pH is in the normal range (7.35 – 7.45) You will need to check the PaCO 2, HCO 3 - and anion gap; Step 3: Is …

Feb 8, 2023 · Step 1 — check the pH. The pH should be assessed first. A pH of less than 7.35 indicates acidaemia — acid in the blood, and a pH greater than 7.45 indicates alkalaemia — alkali in the blood. Step 2 — check the HCO 3 – and PaCO 2

Jan 8, 2024 · If the pH is in the normal range (7.35-7.45), use a pH of 7.40 as a cutoff point. In other words, categorize a pH of 7.37 as acidosis and a pH of 7.42 as alkalemia. Next, evaluate the respiratory and metabolic components of the ABG …

Mar 2, 2025 · This machine measures the partial pressures of oxygen (PaO2) and carbon dioxide (PaCO2), the blood pH, and the bicarbonate (HCO3-) level. These values are crucial for assessing the patient’s respiratory function and acid-base balance.

HCO3-: The bicarbonate level in the blood represents the metabolic component of acid-base balance. In DKA, the HCO3- is usually **lower** than normal, indicating metabolic acidosis. Anion Gap: The anion gap is a calculated value that indicates the …

If PaCO2 is abnormal and pH is normal, it indicates compensation. pH > 7.4 would be a compensated alkalosis. pH < 7.4 would be a compensated acidosis. These steps will make more sense if we apply them to actual ABG values. Click here …
