Purpose:　Gestational　hypertension　(GH)　is　a　serious　health　hazard　for　pregnant　women　and　fetuses.　The　incidence　of　GET　involves　many　epidemiological,　biochemical,　and　hemodynamic　factors.　Methods:　The　current　study　investigated　the　GH　risk　under　the　influence　of　epidemiological,　biochemical,　and　hemodynamic　factors,　and　designed　corresponding　GET　risk　evaluation　methods　and　apparatus.　Results:　The　evaluation　method　has　74.15%　sensitivity　and　81.84%　specificity.　The　ROC　area　under　the　curve　is　0.841.　The　apparatus　automatically　imports　epidemiological,　biochemical,　and　hemodynamic　factors,　and　then　expresses　the　GH　risk　as　numbers,　bar　codes,　and　colors　through　logic　array　analysis.　Conclusion:　The　GET　risk　value　can　effectively　give　the　risk　level　of　GH.　The　GET　risk　barcode　can　improve　the　degree　of　automation　of　information　storage,　transmission,　and　identification　in　GET　monitoring.　The　GET　risk　color　can　also　improve　the　GET　macro　description.
