The method of emergency blood pressure raising is to give rapid fluid resuscitation. Usually hypotension causes intractable shock, and if emergency blood pressure raising is not given, it will cause irreversible damage, so giving rapid fluid resuscitation is the method of emergency blood pressure raising. Usually, intravenous access is established, with 2 intravenous accesses being the main one, and 1 intravenous access is given with supplemental saline and crystalloid for resuscitation, such as supplemental saline and glucose injection. The other intravenous channel is given vasoactive drugs, such as dopamine, which can be used to raise blood pressure urgently. In addition, when emergency blood pressure is raised, ECG, blood pressure, oxygen saturation and other monitoring should be given, and the injection rate should be adjusted at any time according to the results of heart rate and other results.
