Abstract:

Adequate oxygen therapy has become a key to support and care for critically ill patients receiving mechanical ventilation. Adequate oxygen therapy can not only prevent hypoxia and improve the related symptoms caused by hypoxia in major organs, but it may also cause ventilator-associated pneumonia (VAP). There is a certain correlation between hyperoxemia and VAP caused by mechanical ventilation. In this review, we discuss the definition of hyperoxaemia, the relationship between hyperoxaemia and VAP, the possible mechanism for hyperoxemia to trigger VAP, and potential interventions, with an aim to provide reference for improving the prognosis of critically ill patients receiving oxygen therapy and reducing the occurrence of VAP .

Key words: Hyperxemia, Mechanical ventilation, Ventilator-associated pneumonia
