The trend of MAP and the amount of NE. The MAP decreased 5 min after initiating ECMO but remained stable one hour after initiating ECMO in both groups. In response to this, additional norepinephrine was required at the beginning in both groups. Error bars represent standard error of the mean. LD low-dose heparin, HD high-dose heparin, MAP mean arterial pressure, NE norepinephrine
