TW for PD is defined as the weight at which a patient has a normal blood pressure and no fluid in the lungs.

TW for PD is defined as the weight at which a patient has a normal blood pressure and no fluid in the lungs.

• A. Weight at which the patient has a normal blood pressure and no fluid in the lungs
• B. Weight at which the patient experiences minimum blood pressure
• C. Weight at which ultrafiltration is maximal
• D. Weight based on patient preference

Answer: (A)

Target weight in peritoneal dialysis is the weight at which the patient is euvolemic—having normal blood pressure and no fluid in the lungs. This weight represents the goal where fluid balance is right: enough fluid has been removed so that blood pressure stays within the normal range and there are no signs of fluid overload, such as pulmonary edema. In practice, clinicians use this weight to guide how much fluid to remove with each dialysis session and to plan dwell times and exchanges. It’s not about achieving the lowest possible blood pressure, nor about maximizing ultrafiltration in a way that could cause hypotension, nor about choosing a weight based on patient preference. The correct concept is that target weight reflects normal fluid status, evidenced by normal BP and clear lungs, indicating euvolemia.
