What are the two reasons for water treatment?
Prevent equipment damage, patient safety
Aluminum in water used for dialysis causes:
Anemia
Bone disease
Nausea
Vomitting
Chlorine in water used for hemodialysis causes:
Hemolysis
Excess Calcium and Magnesium in water used for dialysis causes:
Muscle weakness
What does the RO remove?
Organic and inorganic materials, bacteria and endotoxins
What are two concerns with using DI tanks?
Exhaust quickly
When exhausted they dump/release previously removed ions back into water
Response to Final Water Quality Alarm:
Bypass
Notify Charge nurse/Fa/Biomed/Medical Director
If not restored must terminate treatments and complete REM
Water/Dialysate culture results:
Acceptable level: below 50 cfu/ml
Action level: 50-99 cfu/ml
Unacceptable level: 100 cfu/ml or >
Water endotoxin results:
Acceptable level: below 0.12 Eu/ml
Action level: 0.12 to < 0.25 Eu/ml
Unacceptable level: 0.25 Eu/ml or >
Dialysate endotoxin testing results:
Acceptable level: <0.25 Eu/ml
Action level: 0.25 to < 0.50 Eu/ml
Unacceptable level: 0.50 Eu/ml or >
What removes chlorine/chlormines?
Carbon Tanks
When do you do Chlorine/Chloramine testing?
Always test while RO is actively supplying water: After the RO has operated for at least 15 minutes, before the first shift of patients, and every 4 hours.
Where should you test chlorine/chloramine?
After primary carbon tank sample port
What is an acceptable result for chlorine/chloramine testing?
less than or equal to 0.1 mg/l
When results are too high post primary take, what actions should you take?
Repeat the test- if still too high- move onto secondary port and test, remember to notify biomed and FA
