Blood pressure can be raised rapidly by the following methods: 1. Patients who are in shock, such as hypovolemic shock, infectious shock, or hemorrhagic shock, should be rapidly rehydrated to increase blood pressure, and active rehydration against shock can raise blood pressure rapidly, such as supplemental saline, glucose water, or low molecular dextrose, which can raise blood pressure rapidly. 2. For patients in hypovolemic shock, blood transfusion is necessary to raise blood pressure rapidly. 3, for patients with lower blood pressure due to infection, antibiotics should be applied, which can also raise blood pressure rapidly. 4, oral medications such as raw pulse drink can also play a role in raising blood pressure.
