We describe the infrastructure that is necessary for hemodialysis HD in the home, focusing on physical requirements, the organization of plumbing and water, and the key features that should guide the selection of machines that are suitable for home use. Introduction. Hemodialysis HD in the home requires specific physical infrastructure, careful organization of plumbing and water, and thoughtful selection of machines that meet the requirements of the patient and his or her environment. Infrastructure. Technical Requirements Necessary for a Dwelling to be Adapted for Home Hemodialysis. There are few dwellings that cannot be adapted for home HD however, minimum technical requirements must be met. A checklist of infrastructural considerations for home HD can be found in Appendix 1. Legal and Financial Requirements. There should be no legal restrictions either central or local government concerning the use of the dwelling for home HD. There are multiple different financial responsibilities in home HD, and these should be transparent among stakeholders, and formalized through binding agreements Table 1. Building Prerequisites. A sound structure is necessary, which should not be affected by dampness, mold, or excessive environmental pollution.

The dwelling must have an appropriate electricity supply to accommodate HD. The supply should be compatible with all equipment, as recommended by the manufacturer, and compliant with local regulations eg, separate circuit requirements, grounding, trip protection. A stable electricity supply is required, usually via the main power source to the dwelling. Supplemental renewable power supplies, such as solar or wind, can also be considered. If it is likely that there will be frequent power failures, the best option is uninterrupted power supply battery backup, which will bridge the power failure until emergency rinse back or disconnect procedures can be completed. Some HD machines have built in battery capacity, and most provide a manual wind back function. Another option is a stand by generator installed at the dwelling with associated control equipment, although this is more costly and complicated. For more information on power outages, see the following Water Supply. The dwelling must have sufficient water supply for HD. In most cases, the feed water for dialysis is sourced from a municipal water supply occasionally, it is sourced from an alternative supply eg, tank, bore, or well. Water consumption varies from 5. Lmin to 1. 50. 0 m.

In most cases, RO machines require a certain level of water pressure to function. Inadequate water pressure can occur for several reasons. Occasionally, the pressure from water mains is inherently unsatisfactory. In other cases, the HD site may be located above ground floor in a high rise building, thereby reducing supply pressure. Occasionally, there is transient decrease in pressure when other water consuming equipment in the house is used flushing a toilet, running a dishwasher, etc. In these situations, the easiest solution is to install a booster pump on the feed water line. This is seldom necessary for ground floor dwelling installations 5 of installations, but not uncommon for installations in high rise buildings. Another option is to install a header tank at the dwelling, although this is more costly and complicated. We conducted an international, multicenter, randomized, doubleblind study involving 1862 patients with ongoing STEMI of less than 6 hours duration, comparing.

If transient decreases in water pressure are unavoidable and troublesome, consideration can be given to a flow fed rather than pressure fed RO unit flow fed RO units have, in effect, a built in miniaturized header tank, which allows for about approximately 6. RO malfunction. Water temperatures across the globe are variable and it may be necessary to cool or heat the feed water. Water temperature issues can make RO units inefficient and sometimes inoperative, so it is important to address water temperature problems when planning for home HD. Where the feed water is too cold, it can be heated by mixing hot and cold water with a thermostatic mixing valve. Where it is too hot, it can be cooled through the use of a heat exchanger. Plumbing Requirements. Reject water from the RO unit is usually disposed of via the dwellings storm water drainage system, although reject water can be redirected back to the RO unit for further generation of permeate in areas where there are severe water shortages. Rather than disposing of reject water, strong consideration should be given to its collection and domestic reuse. Reject water is usually potable, but slightly salty, which limits it for some uses. Notwithstanding, there is abundant experience of reject water reuse as high grade gray water for gardening and horticulture, watering of livestock and agriculture, showering, laundry, general cleaning, toilet flushing, etc. For more information, see The Geelong Experiment, available at http www. The dwelling will need to have options for environmentally sound disposal of dialysate effluent, which is usually managed through sewerage systems or septic tanks. The use of septic tanks for drainage of dialysate effluent is, to some degree, a matter of local customary practice and experience. Vengeance Sample Pack Torrent. Large volumes of effluent may result in a requirement for emptying of the tank at an unsustainable frequency. Of note, septic tanks are not usually used to collect RO reject water, which will dilute the natural microorganisms in the tank that are required to break down sewerage. Theoretically, such dilution can also occur if the volume of dialysate effluent is very large, as might be the case for a patient on nocturnal or daily HD. Another consideration is the disinfection method used for the dialysis machine. If chemicals are used eg, bleach, the dialysate effluent will be bactericidal and may drastically reduce the microorganism count in the septic tank. These variations in circumstances lead to corresponding variations in practice. For example, as a generalization, dialysate effluent is not usually drained to the septic tank in Australia, whereas it is in New Zealand. The disposal of waste into municipal storm water or sewerage systems usually requires a tundish Figure 1, which is a standard plumbing fitting that provides a point of physical separation air break between a machine andor patient and municipal drains. This prevents the accidental back siphoning of drain waste into dialysis machinery, which can occur with cyclical changes in pressure in directly connected drain lines. In most locations, a device to prevent back flow from the intake of the RO unit into the municipal potable water supply is required. This device is called a back flow preventer and it functions as a one way valve on the feed water line. Back flow preventers are installed to eliminate the potential risk of back pressure forcing contaminants eg, bleach from the dialysate circuit into potable water piping.
