What does today's pre-treatment weight minus last treatment's post-weight equal?

The difference between today's pre-treatment weight and last treatment's post-weight represents the Ultrafiltration (UF) goal for the treatment. This calculation is critical in dialysis practice as it indicates how much fluid the patient has gained since the last treatment, which needs to be removed during the current treatment session. The UF goal is determined to safely and effectively achieve the desired volume on the patient, ensuring that they reach a safe post-treatment weight without causing complications due to excessive fluid removal. Understanding this concept helps healthcare providers manage fluid balance in dialysis patients and tailor each treatment to individual needs.
