Extract

We interpret “radiation-like” risk to represent the potential for cellular toxicity caused by low-dose oxygen (LDO) exposure to result in a deleterious clinical outcome. The question asks whether or not patients with COPD exposed to LDO are at higher risk of cellular toxicity (oxygen toxicity) than patients without COPD who are receiving LDO. Because sufficient evidence of the benefit of LDO in normoxemic patients with COPD is lacking,, discussion will focus on hypoxemic patients with COPD.
