A short cut review was carried out to establish whether continuous flow insufflation of oxygen (CFIO) is better than standard ventilation strategies at improving outcome in adults who have suffered an out-of-hospital cardiac arrest (OHCA). Papers were found in Medline and Embase using the reported searches of which four presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that CFIO does not improve survival or return of spontaneous circulation compared with standard ventilation strategies in OHCA.
