Chapter 5—Disinfection and Maintenance
Cleaning the Blood Pressure Cuff
Remove the rubber inflation bag from the Dacron cuff. Both may be disinfected with
commercially available disinfectant soaks. Some disinfectants may cause skin irritation.
Rinse thoroughly to remove any residual disinfectant. Follow the manufacturer's
instructions. Caution is advised when using dark colored soaks which may stain the cuff.
Test a single cuff to ensure that no damage will occur. EtO sterilization may be used.
Caution: If a chlorine bleach solution is used to clean the blood pressure cuff, the service
life of the cuff will be reduced. Do not autoclave the cuff.
Hand washing will enhance the service life of the Calibrated V-Lok cuff. Remove the natural
rubber inflation bag and wash the cuff in warm soapy water; then rinse thoroughly. Allow
the cuff to air dry and then insert the inflation bag. When using machine washing, be sure
that the hook and loop fasteners are engaged so that the hooks do not collect lint or other
fibers. These fasteners can melt at temperatures above 325 °F (132 °C), when being ironed or
pressed.
Water Supply Maintenance
It is recommended that the bacterial quality of both the water and the dialysate be checked on
a routine basis. These checks should take place just before routine disinfection of the system.
Follow the manufacturer's instructions for the operation and storage of reverse-osmosis (RO)
and water pre-treatment equipment.
All sections of the treated water feed system and dialysate delivery machine must be
disinfected regularly to minimize bacterial levels. Each time the treated water system and
distribution piping are disinfected, the dialysis machines should be put into Rinse program.
This allows the disinfectant chemical to feed through the inlet system. Test the water for
residual disinfectant prior to use for dialysis.
Note: The water inlet line is part of the water distribution system and is not disinfected by
the dialysis machine. With some RO systems, the water inlet line may be disinfected along
with the RO and distribution piping by leaving the dialysis machine in Rinse mode during
RO disinfection.
