What is the normal range for blood pH in healthy individuals?

The normal range for blood pH in healthy individuals is indeed 7.35 to 7.45. This range is essential for maintaining physiological processes and biochemical reactions in the body, as even slight deviations can lead to significant health issues.

Blood pH levels are tightly regulated by various physiological mechanisms, including respiratory and metabolic systems. When blood pH falls below 7.35, it is classified as acidosis, which can impair enzyme function and hemoglobin's ability to carry oxygen. Conversely, a pH higher than 7.45 indicates alkalosis, which can affect neuromuscular excitability and other cellular functions.

Maintaining pH within this narrow range ensures that metabolic processes proceed optimally, supports proper cellular function, and helps maintain homeostasis. Understanding this standard pH range is crucial for healthcare providers in order to assess and manage patients effectively, especially in critical care situations.
