What is the normal range for blood pH?

The normal range for blood pH is critical for evaluating a patient's acid-base balance and overall metabolic state. A pH range of 7.35 to 7.45 represents the physiological norm for human blood. This range indicates a slightly alkaline environment, which is essential for various biochemical processes in the body, including enzyme function and metabolic reactions.

When blood pH values fall below 7.35, it suggests acidosis, while values above 7.45 indicate alkalosis. Maintaining blood pH within this narrow range is crucial, as even small deviations can lead to significant physiological effects. Therefore, a blood pH in the range of 7.35 to 7.45 is deemed optimal for sustaining life.
