What is the normal range for arterial blood pH?

The normal range for arterial blood pH is 7.35 to 7.45, which is critical for maintaining homeostasis in the body. This range is essential for proper enzyme function and metabolic processes, as even slight deviations can lead to significant physiological consequences. A pH below 7.35 indicates acidosis, which can occur due to various conditions such as respiratory failure or metabolic disturbances, while a pH above 7.45 indicates alkalosis, which can be caused by hyperventilation or other factors. Maintaining the pH within this narrow range is vital for optimal cellular function and overall health, making it a key consideration in respiratory therapy and patient management.
