High O2 a Go To: Effects of Hyperoxia.

Current research on the optimal amount of oxygen delivery during general anesthesia is controversial. It is well described that anesthesia providers create supraphysiological arterial oxygen levels in patients with the delivery of supplemental oxygen. Over the past 20 years, hyperoxia has been studied more thoroughly and potential consequences are better understood. Atelectasis and radical oxygen species can lead to postoperative complications such as infection, prolonged respiratory support, and increased length of hospital stay. Anesthetists should consider the risk and benefit, potential effects, and differentiate the amount of oxygen dependent on the clinical situation. More research is needed in varying patient populations and surgical procedures to better understand the implications of hyperoxia in patients requiring general anesthesia.
