What is the normal pH range for arterial blood?

The normal pH range for arterial blood is indeed 7.35 to 7.45. This range is critical for maintaining homeostasis in the body, as pH affects enzyme function and the overall metabolic processes. A pH level within this range signifies a balanced state of acid-base homeostasis, which is essential for proper physiological functioning.

If the pH falls below 7.35, it indicates acidosis, which can lead to various health issues including impaired organ function. Conversely, a pH above 7.45 suggests alkalosis, which may also result in serious complications. Thus, understanding the normal arterial blood pH range is crucial for medical technologists and healthcare professionals in diagnosing and managing acid-base imbalances in patients. This knowledge is foundational in the field of hematology and critical care.
