We thank Sharma et al for their critical appraisal1 of our cross-over study on SpO2 readings of different neonatal sensors.2 They suggest inappropriate data collection and misinterpretation of data to explain our findings; we like to comment on these points.

Before going into detail, we would like to point out that we are extremely grateful to Masimo for their continuing efforts in improving pulse oximetry’s performance and thereby patient care. We neither intended to express a preference for one SpO2 sensor type nor to denigrate its measurement precision; as rightly pointed out, this would have required co-oximetry. Also, we agree that the RD sensor’s SpO2 readings reflect SaO2 more precisely and with less variability, as also evident from the tighter distribution of measured SpO2 values in our graphical illustration.

The authors claim that we obtained incorrect …
