The standard range of hypotension is when the upper limb arterial blood pressure in adults is lower than 90-60 mmHg, which is considered hypotension. Hypotension generally has a systolic blood pressure lower than 90 and a diastolic blood pressure lower than 60.

Although hypotension is not a very important disease for patients with hypotension, the harm of hypotension is much more serious than ordinary diseases. Because the elderly who are already in poor health, if hypotension occurs, it will cause a series of complications and even affect daily life in severe cases. Therefore, once cerebral hypoxia occurs in patients with hypotension, their body functions will gradually decline. In daily life, long-term hypotension in patients with hypotension will affect hearing loss, visual impairment, and quality of life.
