Erratum

Following publication of the original version of our article [1] in Critical Care, it was brought to our attention that there was an error in Table 3. Some of the values are incorrect, including arterial oxygen saturation variables and a standard deviation in arterial carbon dioxide tension (mmHg) control group (24 h after N-acetyl-L-cysteine infusion). The corrected table is presented in this erratum (Table 3). This error does not affect the results or conclusions of the study.
