Abstract
Objective To evaluate the effects of preoxygenation strategies on oxygenation stability and stress response in non-mechanically ventilated critically ill patients during intra-hospital transport.Methods A total of 80 critically ill patients transported within Taizhou Hospital of Zhejiang Province from January 2022 to January 2025 were enrolled as study subjects.They were divided into control group(n=40)and study group(n=40)based on the actual pre-oxygenation method employed during transportation.The control group received conventional nasal cannula pre-oxygenation,while the study group received standardized non-rebreather(NRB)pre-oxygenation.Vital signs indices,stress responses,and clinical outcomes were monitored at three time points:the lowest point during transportation(T1),immediately after transportation(T2),and before transportation(T0).Results At T1 and T2,oxygen saturation and partial pressure of arterial oxygen/fraction of inspired oxygen ratio were higher,along with respiratory rate and heart rate(HR)were lower in study group compared to the control group(P<0.05).Incidence of hypoxemia,HR fluctuation>20%and blood pressure fluctuations>20%,and rate-pressure product were lower in study group compared to control group(P<0.05).Although the preoxygenation preparation time was longer in study group,the preoxygenation qualification rate was significantly higher in study group(P<0.001).Incidence of new-onset organ dysfunction was significantly lower in study group compared to control group.Conclusion Standardized NRB preoxygenation effectively maintains oxygenation stability,reduces stress response,and the risk of new-onset organ dysfunction in non-mechanically ventilated patients during intra-hospital transport.关键词
