To the Editor: We read with great interest the article by Jose et al. [
1] in December 2014 issue, comparing oxygen saturation (SpO
2) between arterial blood gas (ABG) and two new generation pulse oximeters. We critically analysed the article and found few issues worth highlighting. In the objectives the authors state that they checked for the correlation, however it is incorrect because correlation is a poor surrogate for agreement [
2]. It was not clear how possibility of bias due to air bubbles was taken care of. Authors preferably should have used at least 1 ml sample for ABG instead of low volume (0.3 ml) because pO
2 in low volume samples is sensitive even to small air bubbles [
