What does a normal blood pH range from?

The normal blood pH range is 7.35 to 7.45, which reflects the body's tightly regulated state of acid-base balance. This narrow pH range is essential for normal physiological functions, as even slight deviations can lead to significant health issues.

The body's homeostatic mechanisms, such as renal function and respiratory rate, play crucial roles in maintaining this pH range. If blood pH drops below 7.35, the condition is termed acidosis, which can impair cellular function and metabolic processes. Conversely, a pH above 7.45 indicates alkalosis, which can also disrupt cellular function.

Understanding this normal range is crucial for healthcare professionals, particularly in nephrology, where they often monitor patients' fluid and electrolyte balances and make necessary adjustments to therapy based on pH levels.
