Abstract：Objective To investigate the application value of home oxygen therapy graded management in elderly patients with chronic obstructive pulmonary disease (COPD) at stable stage. Methods A total of 82 elderly patients with COPD in stable stage admitted to the Joint Logistics Support Force No.900 Hospital Putian Medical District from October 2017 to December 2018 were selected as the research subjects, and divided into the control group (41 cases) and the observation group (41 cases) according to random number table method. The control group received routine intervention, the observation group was given an intervention mode of family oxygen therapy hierarchical management on the basis of the control group. Acute attack and hospitalization during the intervention, forced expiratory volume in the first second (FEV1), FEV1/forced vital capacity (FVC), and blood gas analysis of arterial oxygen content (PaO2) and arterial carbon dioxide content (PaCO2) were compared between the two groups. Results The times of acute attacks and hospitalizations in the observation group were less than those in the control group during the intervention period, and the differences were statistically significant (P＜0.05). After intervention, FEV1, FEV1/FVC and PaO2 in both groups were higher than those before intervention, and PaCO2 was lower than that before intervention, and FEV1, FEV1/FVC and PaO2 in the observation group were higher than those in the control group, and PaCO2 was lower than that in the control group, the differences were statistically significant (P＜0.05). Conclusion The hierarchical management of home oxygen therapy can reduce the number of acute attacks and hospitalizations of elderly patients with stable COPD, improve lung function and hypoxia, and reduce the content of blood carbon dioxide.
