In the original publication of the article, the authors have realized an error in Fig. 1. The corrected version of Fig. 1 is given below.

Fig. 1

Schematic representation of arterial (red line) and venous (blue line) oxyhaemoglobin dissociation curves. In the hypoxic rage (PaO2 < 100 mmHg), arterial oxygenation can be assessed by pulse oximetry (SpO2). As PaO2 increases beyond 100 mmHg, venous saturation (SvO2) at the measurement site increases even though arterial saturation (SaO2) remains maximal and unchanged. This change in SvO2 causes changes in absorption of the incident light (and hence a change in measured signals) as PaO2 changes. With Masimo’s Rainbow SET technology these signals are extractable and the system is able to detect changes in PaO2 through changes in SvO2 at the measurement site. SvO2 reaches a plateau beyond a certain level of PaO2, approximately 200 mmHg (hyperoxic range), and consequently ORI is sensitive to the changes in PaO2 in the range between 100 and 200 mmHg (orange shaded area)
