The impact of oxygen and carbon dioxide management on outcome after cardiac arrest

Abstract

Purpose of Review: To describe the impact of oxygen and carbon dioxide management on patient outcomes following cardiac arrest. Recent Findings: Although there are no data that suggest that supplemental oxygen administration during cardiopulmonary resuscitation is harmful, there is concern that 100% oxygen during the postresuscitation phase may be undesirable. The evidence to avoid hyperoxia is limited to animal studies and retrospective clinical studies that examine the association between exposure and outcome. There is a correlation between end-tidal carbon dioxide values during cardiopulmonary resuscitation and resuscitation outcome, yet this correlation is likely to reflect low or absent..
