Purpose: The purpose of this study was to compare the effects of oxygen therapy on cardiac status and therapeutic outcomes after percutaneous coronary intervention (PCI) and to reduce unnecessary oxygen supply. Our intervention focused on reducing the six hours of oxygen therapy that was previously available to two hours. Method: A non-equivalent control group non-synchronized design was used. After IRB approval, we started experimental study. Total 42 patients participated in this study, 12 in the experimental group and 30 in the con-trol group. The experimental group received oxygen for 2 hours and the control group was compared to the experimental group by chart review of patients who maintained oxygen for 6 hours. We measured Ejection Fraction (EF) by Echo-cardiogram and Myocardial Condition by Myocardium SPECT. We also checked hospital days by reviewing medical chart. For the analysis, descriptive statistics, X2 test, and t-test were used for statistical analysis with SPSS 23.0 program. Results: The test in Myocardium SPECT showed no significant difference in Myocardial condition between the experimental group and the control group. Especially, ‘stress defect’ among the test items was significantly lower in the experimental group than in the control group (t=2.118, p=.040). In addition, there was no significant dif-ference in the hospital day in the experimental group and the control group(t=-0.341, p=.735). Conclusion: Therefore, it is recommend to maintain oxygen therapy for 2 hours reduced and compared previ-ous oxygen therapy protocol.
