Dialysis Efficiency (Kt/V) Calculator
Ideally Kt/V must be greater than 1.2 and URR must be above 65%
What is Kt/V?Like any other medication or treatment, dialysis also has to be tailored to meet the requirements of the patient. The parameter that helps the doctors find out if the dialysis you are receiving is adequate is Kt/V. It is the ratio of urea clearance (K) multiplied by dialysis time (t) to the volume of water in your body. Kt/V values can be improved by either increasing blood flow rate through the dialyser, which increases urea clearance, or by increasing the duration of dialysis sessions.
Additional InformationIt is important to ensure that your dialysis sessions are consistently efficient. You may not immediately feel the harmful effects of waste materials building up in your body, but some symptoms can help you figure out if you are receiving inadequate dialysis.
Watch out for:
- Weakness and fatigue
- Loss in appetite
- Yellow coloration of skin
- Nausea or vomiting
- Bad taste in your mouth
- Loss of weight
- Disturbed sleep
- Prolonged bleeding
There are some simple methods to ensure that you get adequate dialysis.
- Be on time for your dialysis sessions
- Make sure you stay till the end of the treatment session
- Don't settle for lesser treatment time in case the staff wants to leave
- Ensure you make up for time lost during bathroom trips or machine breakdowns
- If you feel uneasy or restless towards the end don't hesitate to ask for help
- Take note of how many times a dialyser is being reused and note down when you get a new dialyser.
- Ensure that a new dialyser is rinsed well with saline before use
- Try to get a new dialyser if you feel a reused one is not working for you
- Strictly follow the fluid intake limits between sessions
