The nasal cannula is widely regarded as a safe and effective means of administering low- and high-flow oxygen to patients irrespective of their age. However, variability in delivered oxygen concentration (FDO2 FDO2 ) via nasal cannula has the potential to pose health risks. The present study aimed to evaluate predictive equations for FDO2 over a large parameter space, including variation in breathing, oxygen flow, and upper-airway geometry representative of both young children and adults. ⋯ A new predictive equation for FDO2 was obtained that accurately matched measured data in both adult and infant airway replicas for low- and high-flow regimens.

The purpose of peer review is to evaluate the scientific merit of the submitted work and to assess suitability for publication. This process is intended to provide an unbiased, independent critique to ensure publication of high-quality manuscripts that demonstrate validity and reliability. ⋯ When given the opportunity to revise, authors should carefully consider all comments and adequately address all concerns. This paper provides guidance to clinicians for both aspects of the peer review process: participating as a reviewer and responding to reviewer feedback.
