Partial pressure of oxygen (PO2) and blood oxygen saturation (SPO2) were assessed 60 minutes after the treatments. A P value <0.05 was considered statistically significant.ResultsThere were significant differences in PO2 (66.2 ± 3.3 mmHg vs 62.1 ± 3.4 mmHg, P<0.05) and SPO2 (97.8 ± 2.1 mmHg vs 94.2 ± 1.7 mmHg, P<0.05) between the groups.ConclusionIn the treatment of elderly patients with ACPE following hip fractures and surgery, high-flow oxygen therapy may be performed to improve ventilation when acute cardiogenic pulmonary edema does not significantly improve within 15 minutes of conventional oxygen therapy.
