Testing for Disinfectant
After a chemical disinfection cycle, the machine must be checked for residual disinfectant
before initiating dialysis. A sample for testing for residual disinfectant can be obtained from a
dialysate line, the UF sample port, or the drain line.
Table 30 – Disinfectant Detection Methods
Disinfectant Detection Method
Formaldehyde Using Schiff’s reagent or a commercially available formaldehyde test,
measure the residual formaldehyde according to the manufacturer’s
directions. The level of formaldehyde should be less than 5 ppm.
Bleach Use facility protocol for detecting chlorine levels in the fluid sample.
Diacide HD Test according to the manufacturer’s instructions using Nephretect or
another test intended for this product.
Power Failure During Chemical Disinfection
If a Chemical/Rinse or Chemical/Dwell program is interrupted, the machine will only allow
Rinse, Chemical/Rinse, or Chemical/Dwell to be selected from the “Select Program” Screen
when power is restored. A message “
Mandatory Rinse ” will be displayed after the Rinse
button is touched.
If a mandatory rinse cycle is interrupted by a power failure, only a Rinse program is available
in the “Select Program” screen. The entire Rinse program must be completed before the
operator can initiate dialysis.
