Erratum

Following publication of our article in Critical Care [1], the following error was brought to our attention. The sentence that reads “The rise in carbon dioxide partial pressure also increases hemoglobin affinity for oxygen and may, therefore, decrease oxygen delivery” is incorrect. The words “increases” and “decrease” were reversed.

The correct sentence should read: “The rise in carbon dioxide partial pressure also decreases hemoglobin affinity for oxygen and may, therefore, increase oxygen delivery.” The original article also unfortunately published with the incorrect cover date. This was published with a cover date December 2015 whereas this should have been January 2016. This has been updated.
