Blood pressure in elderly people is called hypotension if it is lower than 90/60 mmHg. The main manifestations of hypotension are rotation of vision, blurred vision, unsteadiness in standing, palpitations, sweating, and in severe cases, syncope and diaphoresis, so elderly people should try to avoid hypotension. If elderly patients with hypertension are taking antihypertensive drugs, they must pay attention to monitoring blood pressure to avoid excessive lowering of blood pressure, which should be adjusted by a doctor. In addition, the elderly are prone to postural hypotension, which refers to the measurement of blood pressure after 10 minutes of lying down and 3 minutes of standing up. Therefore, it is recommended that when elderly patients change position, especially when changing from the prone position to the standing position, they must pay attention to the slow change of position to avoid the occurrence of postural hypotension.
