What is hem dialysis and how is it connected to ARF?
Hem dialysis is a mechanical process that partly performs the work of healthy kidneys. Hem dialysis uses a man-made membrane (dialyzes) to filter wastes, remove extra fluid from the blood, restore the proper balance of chemicals in the blood, and eliminate extra fluid (edema) from the body. Before you begin hem dialysis, your doctor will need to create an access where blood can flow in and out of your body (dialysis access). This is usually done by inserting a tube (catheter) into a blood vessel in your forearm, chest or groin. Hem dialysis is done in a hospital or dialysis center. A hem dialysis session usually lasts from 3 to 6 hours and must be done 3 times per week. You can read, watch television, or sleep during your dialysis sessions.
