Electrolyte abnormalities - hypo- and hypernatraemia
Description
- Both reflect water balance disorders, not Na+ balance disorders (except rare pure Na+ loss/gain)
- Hyponatraemia - relative water excess (Na+ <135 mmol/L)
- Hypernatraemia - relative water deficit (Na+ >145 mmol/L)
- Classify both by extracellular volume status - hypo/eu/hypervolaemic - this drives management more than the Na+ level itself
