What is the normal pH range for arterial blood gas?

The normal pH range for arterial blood gas is accurately identified as 7.35 to 7.45. This range indicates the balance of acidity and alkalinity in the blood, which is crucial for proper physiological function. A pH value below 7.35 suggests acidemia, while a value above 7.45 indicates alkalemia. Maintaining this normal range is vital because even slight deviations can significantly impact organ functions and metabolic processes.

The physiological processes in the body, including respiration and metabolism, help regulate blood pH, and understanding this normal range is essential for assessing acid-base balance in clinical settings. Monitoring pH levels assists healthcare providers in diagnosing various conditions, determining patient stability, and formulating treatment plans.
