What is the normal pH range of blood?

The normal pH range of blood is indeed 7.35 to 7.45. This range is critically important for maintaining various physiological functions within the body, as even slight deviations can lead to significant health issues. The body has various mechanisms to regulate pH, including the bicarbonate buffer system and respiratory adjustments, to ensure that blood pH remains within this range.

When blood pH dips below 7.35, it is considered acidemia, which can result in a multitude of complications like impaired enzyme function and altered oxygen transport. Conversely, a pH above 7.45 indicates alkalosis, which can similarly disrupt bodily processes. Therefore, the specified range of 7.35 to 7.45 is a vital parameter in clinical settings, informing healthcare professionals about the body's acid-base balance and guiding necessary interventions.
