Sodium Correction Formula:
From: | To: |
Sodium correction calculation determines the time required to correct sodium levels in patients with hyponatremia or hypernatremia. It helps healthcare providers plan safe and effective sodium correction protocols to avoid complications like osmotic demyelination syndrome.
The calculator uses the sodium correction formula:
Where:
Explanation: The formula calculates the time (in hours) needed to reach the target sodium level at the specified correction rate.
Details: Proper sodium correction is critical in managing electrolyte imbalances. Too rapid correction can cause serious neurological complications, while too slow correction may prolong patient discomfort and risk.
Tips: Enter target sodium level in mmol/L, current sodium level in mmol/L, and correction rate in mmol/h. All values must be valid positive numbers with correction rate greater than zero.
Q1: What is a safe sodium correction rate?
A: For hyponatremia, typically 4-8 mmol/L per 24 hours (0.17-0.33 mmol/h). For hypernatremia, correction should not exceed 10 mmol/L per 24 hours (0.42 mmol/h).
Q2: When is sodium correction needed?
A: Correction is needed for symptomatic hyponatremia (seizures, confusion) or severe hypernatremia, always under medical supervision.
Q3: What are normal sodium levels?
A: Normal serum sodium ranges from 135-145 mmol/L. Levels below 135 indicate hyponatremia, above 145 indicate hypernatremia.
Q4: Are there limitations to this calculation?
A: This calculation provides estimated time. Actual correction may vary based on patient factors, ongoing losses, and response to treatment.
Q5: Should this be used without medical supervision?
A: No, sodium correction should always be managed by healthcare professionals due to risks of complications.
