Objective Exploring the construction and application of a nursing early warning system for hypoxemia in patients in the post-anesthesia care unit. Methods This study included 88 patients admitted to the post-anesthesia care unit after general anesthesia at our hospital as the sample. Using a random number table, they were divided into two groups: the control group with 44 patients received routine care, while the study group with 44 patients received interventions based on a nursing early warning system. The nursing outcomes of the two groups were then compared. Results Compared with the control group, the incidence of hypoxemia in the study group was significantly reduced, and the oxygenation index at 48 hours post-surgery was better, with the difference being statistically significant (P<0.05). Conclusion Using a nursing early warning system for patients in the post-anesthesia care unit can effectively reduce the likelihood of hypoxemia and improve patients' oxygenation function.
