Abstract

Oxygen therapy is one of the most famous therapies in critically ill patients with different causes [1]. However, high-pressure oxygen therapy is associated with some advantages and disadvantages [2]. This issue may guide the attention to consider this therapy with careful considerations. However, when the situation is critical health care providers may consider these problems insignificant [3]. Maybe, the most important problem and question in this regard are to consider the pros and cons of this therapy in different concepts. At present time every person will consider that oxygen therapy is essential to critically ill patients without considering the side-effects. The most motivation for the presentation of this article is the recent observations in COVID-19 patients and seeing that there is a wide discrepancy among the time of death in individuals that receive oxygen that is in ICU (Intensive Care Unit) [4].
