About this trial
Hypoxemia was defined as an SpO2 of \< 90% for any duration. Failure to treat promptly can lead to hypoxemia, which may increase the risks of arrhythmia, nausea and vomiting, and cognitive dysfunction. Studies have shown that body position has a direct impact on respiratory function. In special environments, including outside the operating room where emergency airway management for critically ill and injured patients is needed, or in areas with limited medical resources like remote areas, adopting simple interventions by changing position to maintain patients' respiratory function can be more economical, convenient and safe.
