Technology Safeguards, Peaceful Dialysis — HeYou Hospital Blood Purification Center Officially Opens

Imagine if the body's purification factory—the kidneys—suddenly went on strike. How would we maintain the clarity of the water of life? This is where hemodialysis comes into play. However, on this life-sustaining journey, why is the concept of "dry weight” so critical? Before and after dialysis, what details must we pay attention to in order to ensure the smooth progress of treatment? This article will take you through the details.

Hemodialysis, also known as an artificial kidney, or renal dialysis, is a specialized technique used to help the body eliminate waste and maintain balance. We use a machine to draw the patient's blood out of the body, passing it through a dialyzer that utilizes the principle of a "semipermeable membrane." Excess water, toxins, and electrolytes in the blood are filtered out, while the body's deficient bases can be replenished. The purified blood is then returned to the body, replacing the failed kidneys' function of removing water and solutes to achieve therapeutic goals. This process is called hemodialysis. It helps improve symptoms and prolong the patient's life. Many people who rely on dialysis to sustain life use this technology.

Dry weight is the body weight at the end of dialysis, where there is neither fluid retention nor fluid deficiency. When dry weight is achieved, there are no signs of hypovolemia such as hypotension, dizziness, tinnitus, or cramps, nor are there signs of fluid overload such as shortness of breath or palpitations.

Before undergoing dialysis treatment, patients, if their condition permits, must weigh themselves. They should accurately measure the weight of any added or removed clothing, recording the exact value, ideally weighing themselves at home beforehand. This information must be promptly reported to the medical staff to allow for accurate calculation of the ultrafiltration volume.
