Abstract:

Objective： To implement the best evidence-based clinical practice of low-to-medium flow oxygen therapy for adult inpatients under the guidance of the evidence-based healthcare of Joanna Briggs Institute. Methods： The best evidence of low-to-medium flow oxygen therapy for adult inpatients was included in the guidelines and systematic evaluation， and the evidence was transformed into clinical practice through evidence-based practice. Results： The differences of the incidence of percutaneous arterial oxygen saturation（SPO2）， nasal mucosal bleeding and nasopharyngeal dryness between adult non humidified low-to-medium flow oxygen inhalation and humidified low-to-medium flow oxygen inhalation were not statistically significant （Ｐ＞0.05）. Through the analysis of obstacle factors and the implementation of countermeasures， adult non humidified low-to-medium flow oxygen inhalation therapy has been carried out smoothly in clinic， and the purpose of reducing the cost of oxygen therapy and reducing the workload of nurses has been realized. Conclusion： There is still a gap between the best evidence and practice of low-to-medium flow oxygen therapy for adult inpatients. In view of the obstacles to the transformation of evidence to clinical， providing support from the aspects of knowledge， system and material can effectively promote the transformation of evidence to clinical practice.
