What is the reference range for arterial blood pH?

The reference range for arterial blood pH is 7.35 to 7.45. This range is considered normal and is crucial for maintaining the body's acid-base balance. A pH lower than 7.35 indicates acidosis, which can result from various conditions, such as respiratory or metabolic issues. Conversely, a pH higher than 7.45 indicates alkalosis, indicating that the blood is too alkaline.

The importance of this range is evident in clinical settings, as it assists healthcare professionals in diagnosing and managing patients with potential acid-base disturbances. Monitoring arterial blood pH is vital for ensuring that the body’s physiological processes are functioning optimally since even slight deviations from this narrow range can have significant health consequences.
