Arterial blood gas analysis results are important examination indexes in the process of rescuing patients with novel coronary pneumonia.It can objectively reflect the patient’s respiratory function

and is an important reference index for judging the severity of the disease and formulating the treatment plan

which is important for guiding oxygen therapy

regulating mechanical ventilation parameters and correcting acid-base imbalance.In this paper

we analyzed the factors affecting the accuracy of blood gas analysis results and suggested corresponding coping strategies to ensure the reliability of blood gas analysis results and provide real and effective reference information for the formulation of diagnosis and treatment plans for patients with novel coronavirus pneumonia.
