acute myocardial infarction
Conditions
Interventions
experimental group:The subjects routinely inhaled 3 minutes of oxygen through nasal catheters or face masks before the start of emergency PCI until PCI was completed.
Control group:Before emergency PCI, oxygen was inhaled as needed according to the blood oxygen saturation of the subjects, that is, oxygen saturation was acceptable (= 94%), and no oxygen was inhaled
