1A CRITICAL REVIEW OF DIFFERENT TYPES OF OXYGEN FLOWS
Executive Summary
In this article a research, paper by Kepreotes et al., (2017) is being critically appraised using
the CASP tool and guidelines. The difference of effect between standard oxygen therapy and
HFWHO has been reviewed by randomised controlled trial. However, no significant
difference of median oxygen weaning off time was found between the two oxygen delivery
types. Although HFWHO proved to be a rescue tool for children who are in the brink of
being admitted to the ICU. Effectiveness of HFWHO as a rescue tool should be researched
further for better implications in near future.
