Example
- Serum lithium level
- 4.5
- Impaired kidney function
- Yes
Result: Lithium 4.5 mmol/L: extracorporeal treatment (ECTR) RECOMMENDED -- impaired kidney function with a lithium level > 4.0 mmol/L.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Recommended
- decreased consciousness, seizures, or life-threatening dysrhythmias (any level); OR impaired kidney function with a level > 4.0 mmol/L.
- Suggested
- level > 5.0 mmol/L; OR significant confusion; OR expected time to a level < 1.0 mmol/L exceeds 36 h.
What you enter
- Serum lithium level (mmol/L)
- Impaired kidney function
- Decreased level of consciousness
- Seizures
- Life-threatening dysrhythmias
- Confusion
- Expected slow clearance
