Severe hypotension is very dangerous. Hypotension is a diagnostic indicator of shock. Excessively low blood pressure leads to insufficient perfusion of the microcirculation, especially in vital organs such as the brain, heart, and kidneys, which can cause ischemia and hypoxia, leading to the failure of these organs and endangering life safety. Therefore, the occurrence of hypotension, especially severe hypotension, requires active resuscitation. Initially, it is necessary to administer fluids to supplement blood volume and make corrections, while also using some vasopressor medications to treat the disease causing the hypotension, achieving a blood pressure-raising effect to save lives.
