Home Hemodialysis Schedules
There are three basic schedules of HHD and these are differentiated by the length and frequency of dialysis and the time of day the dialysis is carried out. They are as follows:
- Conventional HHD - done three times a week for three to five hours. It is like in-centre hemodialysis (IHD), but done at home.
- Short daily home hemodialysis (SDHHD) - done five to seven times a week for two to four hours per session.
- Nocturnal home hemodialysis (NHHD) - done three to seven times per week at night during sleep, for six to ten hours.
Thus an NHHD schedule results in a larger dose of hemodialysis per week, as do some SDHHD. More total time dialyzing, shorter periods between treatments and the fact that fluid removal speeds can be lower (thus reducing the symptoms resulting from rapid ultrafiltration), accounts for the advantages of these schedules over conventional ones.
A frequent NHHD schedule has been shown to have better clinical outcomes than a conventional schedule and evidence is mounting that clinical outcomes are improved with each increase in treatment frequency. For recent review articles on more frequent dialysis, see and.

Famous quotes containing the words home and/or schedules:
“I will never again go to people under false pretenses even if it is to give them the Holy Bible. I will never again sell anything, even if I have to starve. I am going home now and I will sit down and really write about people.”
—Henry Miller (1891–1980)
“My friend devotes himself to his life, whenever he can find the spare time. His motto is: ‘Don’t just sit there: live!’ So he’s too busy to stand, to walk, to do anything, except to live. He even refused to kiss a girl, when invited, on the grounds that it was time again to be living. Schedules are sacred to him.”
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
