The range of blood pressure control for brainstem hemorrhage must be specifically judged based on the current medical condition at the time. Generally speaking, it is optimal to maintain the systolic blood pressure between 110-120 mmHg. This can both ensure normal cerebral blood supply and reduce the risk of recurrent cerebral hemorrhage due to high blood pressure. However, each patient's baseline blood pressure is different, and many patients have a baseline systolic pressure higher than 180 mmHg. In such cases, it might be appropriate to adjust the target slightly higher, for instance around 130 mmHg. It is recognized that no one’s blood pressure can be perfectly consistent, so a certain degree of fluctuation is acceptable. Unless there are long-lasting high values, in which case, control within a certain range might be needed.
