Kidney health is essential for maintaining the body's overall well-being. When kidneys fail to function properly due to chronic conditions or acute injuries, dialysis becomes a crucial treatment to help remove waste products and excess fluids from the blood. Understanding how dialysis works can empower patients and their families to make informed decisions about treatment options.
Understanding Kidney Function
The kidneys are vital organs that perform several crucial functions. Each kidney contains about one million tiny filtering units called nephrons, which filter blood to remove waste products, excess fluids, and toxins. Beyond filtration, the kidneys also help maintain the correct balance of electrolytes such as sodium, potassium, and calcium — essential for nerve function and muscle contraction.
When kidneys fail due to conditions like chronic kidney disease (CKD) or acute kidney injury (AKI), they can no longer perform these functions effectively, leading to the accumulation of waste products and excess fluids in the blood. Dialysis replicates many of these functions, providing a critical lifeline for patients with kidney failure.
Hemodialysis
Hemodialysis is the most common type of dialysis. Blood is drawn from the body through a vascular access point and circulated through a dialyzer — an artificial kidney — that filters out waste products and excess fluids via a semipermeable membrane. The filtered blood is then returned to the body. Hemodialysis is typically performed three times a week, with each session lasting between 3 and 4 hours.
Peritoneal Dialysis
Peritoneal dialysis uses the lining of the abdomen (peritoneum) as the filter. A sterile dialysate solution is infused into the abdominal cavity through a catheter. The peritoneum acts as a natural filter, allowing waste products and excess fluids to pass from the blood vessels into the dialysate. After a set dwell time, the used dialysate is drained and replaced with fresh solution.
At Celly Mobile Dialysis, we provide CAPD (Continuous Ambulatory Peritoneal Dialysis) and CCPD (Continuous Cyclic Peritoneal Dialysis) services to our facility partners.
Continuous Renal Replacement Therapy (CRRT)
CRRT is a specialized form of dialysis used in the intensive care unit for critically ill patients who are hemodynamically unstable and cannot tolerate conventional hemodialysis. Unlike standard dialysis performed in sessions, CRRT operates continuously — 24 hours a day — providing slow, gentle removal of waste products, fluids, and electrolytes.
Benefits of Dialysis
Dialysis is a life-saving treatment for individuals with severe kidney disease. It removes waste products and excess fluids, corrects electrolyte imbalances, and helps maintain acid-base balance — all functions the failing kidneys can no longer perform. With appropriate dialysis and clinical support, many patients are able to maintain meaningful quality of life while managing kidney failure.
