Erratum to: Intensive Care Med (2014) 40:320–331 DOI 10.1007/s00134-014-3210-2

The electronic supplementary material of this article contained two errors.

Correction 1

In column 2 of Table 7, the last disorder under “Pulmonary disorders” should be “Respiratory failure associated with positive-pressure breathing” and not as published.

Correction 2

Only SI units should be used in the equation for estimates of the serum sodium concentration corrected for the presence of hyperglycaemia and not as published. The correct equation is as follows:

$$ {\text{Corrected}}\,{\text{serum}}\, ( {\text{Na}}^{ + } )= {\text{measured}}\, ( {\text{Na}}^{ + } )+ 2. 4\times \frac{{ ( {\text{glucose}}\, ( {\text{mmol/l)}} - 1 0 0\, ( {\text{mmol/l))}}}}{{ 1 0 0\, ( {\text{mmol/l)}}}} $$
$$ {\text{Corrected}}\, ( {\text{Na}}^{ + } )= {\text{measured}}\, ( {\text{Na}}^{ + } )+ 2. 4\times \frac{{ ( {\text{glucose}}\, ( {\text{mmol/l)}} - 5. 5\, ( {\text{mmol/l))}}}}{{ 5. 5\, ( {\text{mmol/l)}}}} $$
