Oxygen therapy and time to upgrade the oxygen therapy / 中国小儿急救医学

ABSTRACT

Hypoxemia is a common manifestation of many critical illnesses, and oxygen therapy is the most effective treatment for improving hypoxemia.Choosing inappropriate oxygen therapy or delaying the timing of upgrading oxygen therapy may result in persistent cellular and tissue hypoxia, functional impairment, and even organ dysfunction.After starting oxygen therapy, it is necessary to closely observe various indicators such as clinical symptoms, physical signs, pulse oxygen saturation, blood gas analysis, and make full use of various tools such as the respiratory rate oxygenation index, modified respiratory rate oxygenation index, VOX index, L-line diagram model, and online calculators to comprehensively assess the patient′s oxygenation dynamically as well as timely adjust the oxygen therapy mode and parameters to improve patient prognosis.
