Too much of a good thing? Oxygen alert cards are helpful for chronic obstructive pulmonary disease patients at risk of oxygen toxicity

Abstract

It is well established that optimal oxygen therapy needs to be provided for patients with COPD while they are being transferred to hospital, or assessed in A&E. (Murphy et al 2001, Durrington et al 2005). The objective is to give appropriate oxygen to support their needs while avoiding the risk of CO2 retention and respiratory acidosis. https://thorax.bmj.com/content/61/suppl_2/ii57 This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial. http://creativecommons.org/licenses/by-nc/4.0/
