The normal pH range for arterial blood is between 7.35 and 7.45, which is crucial for maintaining proper physiological functioning. This range reflects a state of homeostasis where the bicarbonate buffer system effectively regulates acidity and basicity within the body. Maintaining pH within this range is vital for enzymatic activities and metabolic processes, as enzymes and other cellular functions are pH-sensitive.

When the pH of arterial blood drops below 7.35, it indicates acidosis, which could be due to respiratory issues, metabolic problems, or other conditions affecting acid-base balance. Conversely, if the pH exceeds 7.45, it suggests alkalosis, potentially resulting from hyperventilation or excessive loss of acids. An understanding of these ranges is essential for laboratory professionals and clinicians monitoring patients’ acid-base status, guiding diagnosis and treatment decisions for conditions like respiratory failure or metabolic disorders.
