A high pressure of 131 mmHg and a low pressure of 87 mmHg are generally considered normal blood pressure. For normal adult blood pressure, blood pressure values are mostly less than 140/90mmHg, while high normal blood pressure values refer to systolic blood pressure between 120-139mmHg and diastolic blood pressure between 80-89mmHg, and normal ideal blood pressure refers to blood pressure <120/80mmHg. For high pressure of 131mmHg and low pressure of 87mmHg, whether it is normal or not depends on the patient's basal blood pressure For patients with high BP 131mmHg and low BP 87mmHg, it depends on the patient's basal BP status and the presence or absence of symptoms. In patients with high basal blood pressure, a sudden drop of 30% or more from the basal value, accompanied by peripheral hypoperfusion and cold extremities, should be considered as a possibility of shock.
