Dialysate pH should be maintained in which range?

Dialysate pH should be maintained in which range?

• A. Between 5.5 and 6.5
• B. Between 6.0 and 6.5
• C. Between 6.9 and 7.6
• D. Between 7.6 and 8.0

Answer: (C)

Dialysate pH is kept near normal body pH to avoid shifting the patient’s acid–base balance and to protect the dialysis circuit and blood cells. In modern hemodialysis, dialysate is bicarbonate-based and formulated to be essentially physiologic, usually around 7.0 to 7.4. To stay within safe limits and align with equipment and patient comfort, a dialysate pH in the range of about 6.9 to 7.6 is targeted. If the pH is too low, the dialysate is acidic, which can cause patient discomfort and metabolic acidosis risks; if it’s too high, it can lead to alkalosis and related issues. Thus, the 6.9–7.6 range best maintains physiological conditions during treatment.
